If
you’re confused about the benefits of prohormones, don’t feel alone.
When the United States Congress passed the Food Supplement act of 1994,
it opened the door for formerly esoteric food supplements, including
prohormones. The term “prohormones” doesn’t refer to any secret drugs
used by professional athletes. Instead, it refers to steroidal compounds
that can be converted into hormones in the body, including both
testosterone and estrogen, as well as various hormonal byproducts and
metabolites.
In the beginning, the prohormone market
was simple. You had Mexican yam supplements that were wrongly thought to
convert into active hormones (they do, but only with the assistance of
certain enzymes not found in the human body); and dehydroepiandrosterone
(DHEA). DHEA, still a popular supplement, acts as a precursor for both
testosterone and estrogen, as well as a formerly little known
intermediate in the steroid biosynthesis pathway called
“androstenedione.”
DHEA may provide health benefits
related to antiaging properties, but as a testosterone precursor, it
left much to be desired. For example, in women, it nearly always
converts into testosterone, but in men it’s fate isn’t as certain. In
most cases, males convert DHEA into androstenedione, and from there it
can take numerous pathways--including the undesirable estrogen route.
While it would appear that androstenedione, which has a far more direct
conversion into testosterone is a better choice than DHEA, only one man
initially recognized this fact.
That man was Patrick
Arnold, 33, a Seymour, Illinois-based chemist with an extensive
knowledge of both chemistry and particularly, prohormones. Arnold has a
bachelors degree in chemistry and 3 years of graduate study in chemistry
from the University of Connecticut. When the public furor over baseball
slugger Mark McGwire’s use of androstenedione peaked, Arnold was a
sought-after expert on the effects of androstenedione. To provide a pure
source of this prohormone, and subsequently others, Arnold formed a
company called LPJ, with which he continues to pursue both prohormone
sales and development.
But recent negative studies
published about the effects of androstenedione have cast a pall over the
use of prohormones for bodybuilding purposes. Add to this the ever
increasing roster of various prohormones introduced since
androstenedione hit the market a few years ago, and you can’t help
getting confused about both the effects and benefits of these
supplements.
The latest types of prohormones even
feature allegedly superior delivery systems, such as cyclodextrins and
liposomes--words familiar to some scientists, but likely to draw a blank
with the hoi polloi of bodybuilding. Both refer to special delivery
systems designed to optimize prohormone absorption. Cyclodextrins use a
carbohydrate-enveloping effect with prohormones, while liposomes act in a
similar manner using a fat-envelope. The effect is somewhat like a
“Trojan horse,” allowing prohormones to bypass initial near-complete
destruction in the liver. But this isn’t as simple as it appears. Are
some cyclodextrin products better than others? How does liposome
delivery compare with cyclos? Let’s clear up the confusion here and now
by going to the guru of prohormones himself--Pat Arnold.
Q: A new
type of delivery system for prohormones is about to emerge called
“liposomes,” what are they, and how does this type of prohormone
supplement compare with cyclodextrin prohormone delivery?
A:
Liposomes are bi-layered shells made from certain kinds of lipids. These
particular kinds of lipids, i.e., fatty acids, phospholipids, have a
fattylike or non-polar end to them, combined with a more waterlike or
polar end, and a long-chain structure. What these lipids can do in water
under the right conditions is line-up in such as fashion that all the
polar ends are sticking out from a center in which the non-polar ends
are anchored.
The whole thing folds upon itself,
giving a shell with a water-soluble exterior and a oil soluble interior
(somewhat similarly to cyclodextrins). Non-polar drugs, such as
steroids, can be trapped in the non-polar tails of the lipid chains in
the interior of the liposome. These shells can also be formulated to
have many layers, like an onion. The non-polar drugs, including steroid
prohormones, can be trapped in the non-polar portions in each layer.
Some
manufacturers have made prohormone liposome products, mainly for oral
consumption. When a prohormone liposome is ingested, it passes through
the stomach into the small intestine. In the small intestine, the
liposomes come into contact with the non-polar intestinal cell lining,
merging with it. Picture two soap bubbles merging together. When this
happens, the prohormone trapped in the interior of the liposome is
efficiently transferred into the intestinal lining. From there, it
travels into the portal circulation to the liver.
Multi-layered
liposomes take longer to completely merge with the intestinal lining
cells and deliver their contents. So these are used to provide a more
sustained delivery compared to single-layered liposomes. A product that
contains different sized liposomes of various layer amounts should
theoretically provide a time-released delivery of prohormones.
A
single-layered liposome encapsulated prohormone should work similarly
to a cyclodextrin (hydroxypropyl-beta-cyclodextrin) complexed
prohormone. In other words, put the steroid in a water-soluble shell,
then deposit it in the lipidlike surface of the oral or intestinal
mucosa. However, the flux between the cavity of the cyclodextrin
molecule and the mucosa is far more efficient and faster than liposomes.
A liposome must first merge and dissolve into the mucosal cell membrane
before its contents are delivered. In contrast, the cyclodextrin
molecule undergoes no such interaction at the mucosal membrane, and does
not disintegrate; it simply instantaneously delivers its prohormone
payload.
A possible advantage of liposome delivery over
cyclodextrins is that liposomes may provide a time-released delivery
effect through using multilayered liposomes. However, I don’t believe
that prohormones should be given in a time-released fashion, because
doing is relatively ineffective.
My conclusion about
liposome products is that single-layered liposomes featuring good
manufacturing standards are a great oral product, and may also be
effective sublingually (under the tongue). But I see little or no
promise in the multi-layered, controlled release liposome products. In
addition, I don’t think even the single-layered liposome products work
as well as the cyclodextrin-complexed products.
Q: What happens to
standard prohormones in the liver, and could they be toxic to that
organ in a manner similar to anabolic steroid drugs?
A:
Prohormones in the liver are for the most part metabolized into inactive
end products, such as androsterone and etiocholanone. These end
products are then usually conjugated with glucuronic acid, which renders
them water soluble. They can then be excreted in the urine.
These
processes used to metabolize natural steroid hormones are not
significantly stressful to the liver. The medical literature shows that
non-ankylated steroids such as these do not cause any toxic effects in
the liver, even at relatively high doses.
Many doctors
and uniformed scientists are lumping all androgenic steroids in with
ankylated oral androgens (such as the anabolic steroids
methyltestosterone and oxymetholone or Anadrol). Such synthetic
ankylated oral steroids feature chemical alterations enabling them to
resist certain metabolic deactivations in the liver. As a result of
these alterations, a toxic burden is imposed on the liver. Prohormones,
which don’t have such alterations, are therefore nontoxic to the liver.
Q) What advantages do cyclodextrin prohormones have over standard prohormones?
A:
Cyclodextrin-complexed prohormones, and we are speaking here of the
highly soluble hydroxypropyl-beta-cyclodextrin complexed products--not
the inferior, poorly soluble beta-cyclodextrins, render prohormones
water soluble and are efficiently absorbed into mucosal tissues (mouth,
nasal, intestinal lining). This delivery is far more efficient compared
to simple prohormone powders in capsules.
A major advantage
offered by cyclodextrins is that they have good delivery efficacy
through non-gastrointestinal routes, such as under the tongue, thus
preventing the usual extensive first-pass liver destruction that happens
with most standard prohormones. The result is a far higher blood
androgen response per each milligram of prohormone administered. Cyclos
will be much less bioavailable when taken orally, but they are still
superior to simple encapsulated powdered prohormones.
Q:
Are cyclodextrin prohormones (CPH) harmful from a health perspective in
any way? For example, can they adversely affect blood lipid levels in
manner similar to oral anabolic steroids?
A: Cyclodextrin
prohormones, in fact all prohormones, share the same potential health
risks associated with prescription testosterone and other steroid drugs.
These include possible negative effects on cholesterol (lowered HDL
levels); male pattern baldness; acne; gynecomastia (male breast
development); prostate gland enlargement; depression of endogenous
testosterone production, among others.
On the other
hand, cyclodextrin prohormones may present far lower risk of certain
side effects. For example, the liver is the site of cholesterol
synthesis and lipoprotein production, as well as being quite rich in
aromatase enzyme activity (aromatase converts testosterone into
estrogen). Since cyclo products avoid first-pass metabolism in the
liver, and require lower dosages, I would think that side effects such
as HDL depression and gyno should be minimized by this dosage form. In
fact, cyclodextrins have been shown to reduce cholesterol when taken
orally. They can complex with ingested food cholesterol and inhibit the
absorption of such food-contained cholesterol.
Q: What’s the optimal way to take CPH in regard to dosage, timing, with or without meals and so on?
A:
CPH are only available in sublingual form now, so I’ll only comment on
that. In a study conducted by researchers at East Michigan University,
25 milligrams of cyclo-diol gave similar blood responses to 50
milligrams. However, we never tested anything less than 25 milligrams,
so we still don’t know if lower milligram amounts are just as effective
as 25 milligram doses.
CPH should probably be taken an
hour before meals, since some prohormone may still be unabsorbed in the
mouth for some time after the lozenge is dissolved. You should not drink
anything for perhaps 10 to 15 minutes after the lozenge is fully
dissolved. I think for most young men, these cyclos should be taken at
least three times a day. You can take more, but it doesn’t make sense to
take more than has been found effective.
Q: Can women use CPH safely, and if so, at what doses?
A:
Women can probably take a cyclo-nor-diol prohormone. I know that many
fitness competitors love nor-prohormones, and cyclos are the best way to
take them.
I won’t make up things just to impress you.
I really have not investigated the use of prohormones by women that
much, and as such, aren’t secure enough to suggest recommended dosages
for them. I plan on doing some interview-type research with women nor
users to determine what they are using and finding to be safe. Also,
what, if any, side effects they may be experiencing. I have to do this
because I think few women would volunteer for a dose-response study on
an androgenic product [produces male pattern side effects, including
facial hair growth, and so on].
I hope to learn a lot
more on the use of nors by women, and then write an article in one of
the women’s fitness magazines discussing my findings. I may even decide
to market a lower dosage type of prohormone specifically for women. Any
female athletes who are reading this and now using prohormones should
contact me by mail at parnold8@ix.netcom.com, and discuss their results
with me. I would be very appreciative for this feedback, and will
certainly respect their anonymity if they wish.
Q:Are slow-release and absorption a desirable aspect of prohormone supplements?
A:
I believe that sustained release oral prohormones are probably
ineffective for the most part, and that the whole idea of sustained
release runs counter to what science has demonstrated concerning the
liver metabolism and oral bioavailability of these compounds.
The
reasoning behind this assertion is based on bona-fide research showing
that compounds easily deactivated in the liver require large amounts to
increase blood levels. The reason for this is that large amounts will
overwhelm the liver’s degradation capacity and allow undestroyed
compound (prohormone) to pass through into the general circulation. In
contrast, a time-released product will provide a trickle of prohormone
to the liver over a longer time period. As a result, the small trickle
is easily metabolized and not much will get into the blood.
I
believe that oral prohormones should be taken in three relatively
massive divided doses throughout the day. I’ve found this technique to
be extremely effective, leading to significantly elevated blood androgen
levels during most of the day. These oral doses can be given as single
layered liposomes or cyclo complexes (the most orally bioavailable), or
as micronized (next best, but expensive) formulations or as simple
prohormone capsules (best bang for the buck as far as orals).
Q:
Besides the recent adverse studies related to androstenedione, one as
yet unpublished study showed some good effects related to
prohormones--can you tell us about that study and what it found?
A:
This study was different, in that the featured prohormone wasn’t
androstenedione, but 4-androstenediol (4-AD or Androdiol). The study was
done at Eastern Michigan University, and examined the effects of a dose
of 450 milligrams a day of 4-AD for 4 weeks. The results showed
significant lean mass gains in the study subjects, and also significant
strength gains. There were no significant effects on beneficial high
density lipoprotein cholesterol (HDL), although this type of “good”
cholesterol carrier actually increased in the 4-AD group. In addition,
the study found no adverse effects on estrogen levels, luteinizing
hormone level (a pituitary hormone that controls testosterone levels in
the body), and blood markers for liver toxicity.
I’m
starting to sound like a broken record lately, as I have constantly
tried to beat into the public mind that there’s a huge difference
between 4-AD and androstenedione. 4-AD does not convert directly into
estrogens like androstenedione, and is a far more efficient precursor
for testosterone. This study could help further my cause, but the study
author has experienced difficulty getting it published. Not because of
any inherent flaws in the study, but merely for reasons of prejudice
against these prohormones.
My company, LPJ, and other
companies are co-funding an even more comprehensive safety and efficacy
study on 4-AD next year, and I hope the sheer weight of available
evidence from these studies finally forces someone to publish the data.
Q: Did the East Michigan Study use the cyclodextrin form of 4-AD?
A: No, I believe they used a simple chewable formulation, which of course involved oral intake.
Q: Would larger doses than what is usually suggested lead to better results with prohormones?
A:
Undoubtedly. Dosages under 500 milligrams a day lead to so-so results.
Many people have tried this, became disappointed, and then simple wrote
off prohormones as ineffective. I am confident enough now, from what
I’ve seen in athletes and in myself, to say that oral doses of 1,000
milligrams or even 2,000 milligrams a day of 4-diols (Androdiol or
norandrodiol in a stack) lead to impressive results--even dramatic
results--with no great increase of side effects. The lack of gyno seen
with even mega-doses of 4-diols amazes me, leading me to wonder if the
diols themselves in the unconverted form might not impart some kind of
antiestrogenic activity. This is a long shot, I guess.
Larger
doses produce not only greater blood androgen concentrations at peak,
but a far more protracted time in which significant elevations are
present in the blood. Three daily doses of 400 milligrams or so should
elevate testosterone to the extent that daily blood levels are either
far above normal or at least significantly elevated. This kind of cycle,
however, should not be done for more than 6 to 8 weeks, and at least
that much time should be taken off in between. Remember, you are
elevating your androgen levels nearly all the time, so some LH shutdown
due to negative feedback inhibition is an unavoidable consequence. As a
result, you need to allow your endocrine system time to get going again.
The same is true for androgenic/anabolic steroid drugs.
Q: Which is more expensive to produce and sell: hydroxy or beta cyclodextrins?
A: They aren’t too different as far as production costs, but the raw materials for hydroxy complexes are far more expensive.
Q:
Since the hydroxypropyl-beta-cyclodextrins (HBC) is more water-soluble
compared to the beta-cyclodextrins and is far superior, to your
knowledge are there any commercial prohormone products currently
marketed that contain the more desirable HBC form?
A: I believe Supertech, OSMO, Kaizen, Sportpharma, and my company, Ergopharm, sell HBC complexed prohormones.
Q:
Do you think that the recent adverse publicity related to
androstenedione will turn-off consumers considering the use of any type
of prohormone supplement?
A: I don’t think, I know. I
sometimes end up talking to strangers in gyms and health food stores
around the country, and when the subject of prohormones comes up, the
general response is “I’m scared of that shit” or “I’ve heard it makes
you grow tits” [an objection presumably voiced by males only], or
something like “I’ve tried that Andro-6 stuff and it didn’t do anything
for me.” The media succeeded in imparting a big scare into consumers
regarding prohormones following the publication of those adverse andro
studies. That, coupled with the fact that many people tried the stuff at
the old recommended dosages that I know to be suboptimal and
ineffective, led such people to conclude that prohormones are just a
ripoff. This has hurt the industry somewhat. Because of all these
misconceptions, I’ve been trying to re-educate people about the
differences between diones and diols, and what dosage patterns and forms
should be used to see the promised results.
Q:Do you think the
Food and Drug Administration (FDA) is trying to remove all prohormone
supplements from the market? How would they accomplish this?
A: I
don’t think the FDA is trying to get rid of prohormones, but the Drug
Enforcement Agency (DEA) is certainly zealous in this regard. The FDA
has limited power, and can’t remove prohormones from the market unless
they prove clearly toxic in some way. Since, thus far, this toxicity
hasn’t emerged, the FDA can’t act yet.
But the DEA,
which also monitors illicit anabolic steroid usage, has their sights set
on prohormones. Now, the target is just androstenedione; however, if
the DEA can get rid of androstenedione, the other prohormones will also
go like dominos. Federal drug czar, Barry McCaffrey, has publicly stated
that he has an agenda to remove that “dangerous andro” from the market
for the sake of our children’s lives.
The plan, as I
know it--and this isn’t a secret--is for the government to fund a test
(probably on animals) that provides massive amounts of androstenedione,
possibly by injection, to prove there is some anabolic activity. Without
a doubt, androstenedione is anabolic at megadoses, and when they find
this, they can then say that androstenedione fits all the
classifications of being an anabolic steroid under the 1990 Anabolic
Steroid Control Act. Androstenedione would then be categorized as a
class-3 controlled substance, meaning that possession of it will
constitute a felony.
Since no one can show that
prohormones are overtly dangerous, I can only deduce that our government
considers muscle building to be a threat to society. What other
explanation can there be?
Q: Considering the recent studies
showing adverse effects associated with androstenedione, do you now
consider this prohormone ineffective, or still useful for some purpose?
A:
I consider androstenedione too weak and too much of an estrogen
precursor for chronic bodybuilding use. However, I think it may be quite
effective as a libido booster, since both androgens and estrogens are
responsible for sex drive.
Q: In terms of anabolic effects, how do prohormone supplements compare to actual anabolic steroid drugs?
A:
Anabolic steroid drugs have varied abilities to pack on muscle weight
and different propensities for water retention. Regarding prohormones,
the 4-diols at high dosages seem to produce gains similar to moderate
doses of testosterone and nandrolone. I’m speaking here of doses equal
to 1,000 to 2,000 milligrams of 4-AD, nor-4-AD, or a daily combination
of both. I realize that people are likely to roll their eyes upon
reading this and say,”Here goes the bullshit again,” but I say let them
go out and give it a try for a few weeks.
Q: Would the side effects, if any, for CPH be similar to that of anabolic steroid drugs?
A:
On a qualitative basis, the side effects from 4-AD are similar to
testosterone as far as water retention and androgenic effects go, but
the gynecomastia risk seems to be substantially lower. The side effects
from nor-4-AD are qualitatively similar to nandrolone.
Q: Should certain people avoid taking any type of prohormone supplement?
A:
Anyone who has a medical contraindication to avoid androgen drugs, such
as testosterone or nandrolone esters, should not use prohormones. This
includes people with prostate cancer, breast cancer, and those who have
not yet reached full linear growth (final height, as in teenagers). To
find out other examples of people who should avoid using prohormones and
associated precautions, as well as possible side effects, check the
entry for “testosterone” in the Physician’s Desk Reference.
Q:
Since testosterone appears to play a role in prostate gland enlargement,
should men with this condition avoid using prohormones?
A: Not
necessarily. They may be able to use a 5-alpha-reductase inhibitor [such
as finisteride or Proscar] with their 4-AD and still be okay. Or better
yet, they may find that a nor-prohormone like nor-4-AD actually helps
their prostate by competing with testosterone (more specifically, norDHT
competing with dihydrotestosterone, the testosterone metabolite
responsible for prostate enlargement) in the prostate, resulting in far
less androgenic stimulation and growth. However, I must advise anyone to
check with their doctor first--even though their doctor is likely to be
clueless about the subject, and too scared to suggest anything but
staying away from all prohormones.
Q: Some people have suggested that 19-nor prohormones may cause impotence due to a progestinlike structure--is this possible?
A:
This is sheer baloney. Nandrolone does have a weak progestogenic
activity, but even so, progestins have never been implicated in reducing
libido. The only exception to this is when the progestin in question
also had antiandrogenic qualities, due either to cell receptor
antagonism or indirectly by suppressing luteinizing hormone from the
pituitary gland.
But it’s true that 19-nors may
decrease libido or sex drive by competing with testosterone at the level
of the central nervous system, i.e., in the brain. This results in less
androgenic stimulation in brain centers controlling sex drive.
Q: Are there any specific food supplements or nutrients synergistic with prohormones?
A:
I hate that word “synergistic,” because it’s so often misused and
abused in the supplement industry. I would say there’s nothing
synergistic out there, but a high protein diet that also supplies other
ergogens can only help increase gains during a prohormone cycle.
Q:
Should people concerned about androgenic side effects, such as male
pattern baldness, acne, and prostate enlargement, stick with only 19-nor
prohormones?
A: For the most part, yes, if they want to play it smart.
Q: What are the maximum and minimum effective doses for CPH?
A:
I have to admit that at this time, I don’t know. What I do know, based
in the results of the East Michigan University study discussed earlier,
is that taking more than 25 milligrams at one time won’t do any good.
The optimal dosage lies somewhere between 5 and 25 milligrams, and I
will someday find the precise dose.
Q: Can taking CPH 3 times a day or more lead to a feedback suppression of endogenous testosterone synthesis?
A:
Used 3 times a day, I don’t think so. At least I know that cyclodextrin
testosterone taken 3 times daily resulted in suppression only while the
testosterone levels were elevated, and when they returned to normal, so
did LH. I would expect the same to be true for CPH. I don’t know at
which level over 3 times a day that you would reach a level of
suppression that would not fully return readily to normal testosterone
output.
Q: Would using any of the CPH forms of prohormones increase aggression?
A:
My view on the entire ‘roid rage thing is that people who are assholes
tend to be worse assholes when they build muscles. People with normal
temperaments just get more confident for the most part.
Q:Are there any currently available natural estrogen antagonists that are effective?
A:
I think indole-3-carbinol and its derivative, diindolymethane, are
potentially effective compounds. However, I don’t know how well they are
working in the real world at this time. I introduced a flavone called
chrysin in 1996. But I always demanded that in-vivo testing be done
before it was marketed. Despite the lack of such “in the body” tests,
various companies marketed it based solely on hype.
Last
year, my company, for a measly $350, funded a simple test on chrysin
using rats as subjects. We had several groups, such as those receiving
the chrysin as injections, orally, or other rats given a placebo for
each of these. The results showed no effects of chrysin on estrogen, but
the rats did get fatter after using chrysin.
Q: Regarding DHT,
the “bad byproduct” of testosterone linked to male pattern baldness,
acne, and prostate enlargement, some people suggest that the herb saw
palmetto may reduce DHT synthesis. Would it be a good idea to take saw
palmetto concurrently with CPH?
A: No, unless you are taking the
herb for some health reason. The problem with saw palmetto is that it
may potentially reduce the effectiveness of prohormones.
Q: To your knowledge, are there still untapped possible prohormones that have yet to be marketed?
A:
As far as androgenic prohormones, I know of at least one that still
isn’t marketed. But it has no advantages over the current best types of
prohormones that are available, so there isn’t any actual reason to
market this particular substance. I believe the androgen prohormone
possibilities have been exhausted as far the best ones go. Someone may
place a synthetic (perhaps unknowingly) on the market and call it a
prohormone, but that’s breaking the law, and not what we’re talking
about.
I do know of a steroidal prohormone that isn’t
androgenic, yet may have some valuable athletic benefits. I don’t want
to discuss anything more about it now, but this will definitely be a
future product of my company.
Q: What type of future effective
delivery systems for prohormones do you anticipate; in fact, what do you
view as the future of prohormones in general?
A: I think an
aqueous solution of cyclo prohormones, taken intranasally, would be
quite effective, especially prior to a workout. The nasal passages go
high up into the head, right next to the base of the brain. Absorption
through these membranes should promote an amplified central nervous
system effect. I have, in fact, made these for my own use and found them
to be potent enough to feel right away.
I have
developed a sustained-release cyclo product made to stick in a
particular part of the mouth and dissolve very slowly. This product will
provide both the high bioavailability of cyclo prohormones taken
through a route that bypasses the liver, as well as a sustained release
into the blood. On top of that, with this product there is virtually no
bitter taste problem as is the case with sublinguals. I said earlier
that sustained release delivery of orals is a bad concept because of
liver degradation. However, this new product, being better absorbed
through the lining of the mouth, doesn’t undergo first-pass liver
metabolism, and thus is very suitable for sustained release. This stuff
required extensive research and formulation work to get right, so I
would expect that anyone who tries to produce a knock-off product would
probably create a crappy and obvious counterfeit.
