[rumbleboy]

Giant Nutrition announces the newest, and to date the greatest breakthrough in methylated androgen technology - STS-646 (aka mestanolone). This product is available as of today through *************

Read below to learn more about one of the most famous - and infamous - steroid compounds of all time. And then order your own bottles while the product is still legal and in stock (which won't be for very long!!!!)

STS-646:

The Ultimate in Pre-workout ‘Testosterone’?

It’s out there somewhere. Statistically speaking, it could be argued, there is a chance that nature is hiding 5alpha-androstan-17alpha-methyl-17beta-ol-3-one (a.k.a. 17alpha-methyldihydrotestosterone, or mestanolone). Maybe it is in some plant, an undiscovered species of sea cucumber, or some other form of life. It may even be circulating through your blood at this very moment.

STS-646: What made it so popular with the Germans?

But obtaining the compound in useful quantities from nature would likely be prohibitively inefficient. So human beings decided to craft it for themselves. This allowed scientists from Germany, the nation responsible for developing some of the planet’s most buff athletes, and, more recently, bringing us the 4.5-year-old ‘Muscle Boy’, to begin experimenting with it. They affectionately gave it the code name ‘STS-646’ and tested it on humans. That’s when something surprising took place.

A pair of scientists patented STS-646 upon discovering, quite by accident, that its oral administration “led to an optimization of the central nervous system [CNS] activation” in humans during physically stressful tasks (U.S. Patent #5,591,732). Translation: STS-646 enables your brain and spinal cord (i.e., the CNS) to orchestrate muscular activity more efficiently. It thereby enhances athletic performance.

STS-646 was commercialized in a number of countries, including the United States. So what happened to it? Was it not all it was cracked up to be? Did its ‘bad’ effects outweigh the ‘good’?

Some nations still sell STS-646, usually under the generic name mestanolone. Perhaps the biggest single challenge faced by the drug was the insatiable human appetite for new drugs. Scientists like to tinker. Thus, they continued to synthesize away with their chemistry sets, hoping that they could produce something better, or at least, usefully different.

“Nonetheless,” one well-known steroid industry expert and chemist (who wishes to remain anonymous) remarked to me the other day, “for performance enhancement [STS-646] remains one of the best. The East Germans had dozens of compounds at their disposal; they chose it as one of their faves for a reason…”

“One of their faves”, indeed. It has been reported that STS-646 was one of the East German government’s most popular doping substances in competitive sport; the second most frequently used oral androgenic steroid overall (Franke and Berendonk, 1997). Clearly, it must have done something worthwhile.

But does it build muscle?

Now I don’t know about you, but I don’t care too much about athletic performance. I’m more of a cosmetic bodybuilder, constantly trying (but never quite managing) to please my vain ego. I just want to look good.

Still I’m always on the lookout for a safe and reliable workout intensifier, something that can give me a pleasant boost of mood, greater muscular ‘oomph’, and better pumps. All of this can be argued to enhance my ability to build muscle. All of this has been suggested to be possible with oral administration of STS-646.

There’s that word again –‘suggested’. Too often it is a disguise for “I heard it through the grapevine” or something equally dubious. And so it is here. Indeed, if you’re looking for double-blinded clinical studies to provide evidence that STS-646 will make your muscles bigger and leaner, then you’re fresh out of luck. As is often the case in bodybuilding, the knowledge about drugs like STS-646 is largely empirical, based more on observation (i.e., ‘real-world’ trial and error) than rigid scientific scrutiny.
So what are ‘real-world’ STS-646 users saying? Are there any?

Below I’ve pasted some feedback from STS-646 (mestanolone) users collected off of various online bodybuilding-related discussion forums. Granted, such forums aren’t the most reliable source of information; nevertheless, their comments can provide some interesting, if not useful, insights. Usernames have been omitted to protect the guilty.



“[Mestanolone] has passed with flying colors so far in the first 10 days of a 20 day trial run.

The dosage was set at 2 capsules per day and the length of the administration has been 10 days thus far.



Results:

-Noticeable fat tissue reduction
-Muscle hardening
-Slight jump in energy when administered within one hour of an afternoon training session
-Nice moderate pump
-Moderate strength increase
-No joint pain (as often experienced with winny) [Winstrol]”

“It's great on low cal diets when body fat is low enough...good pumps

“It’s an awesome cutting drug…

“…I love [mestanolone]…super strength, water loss, ripped to the bone, increased libido, no aggression changes.”

“I tried [mestanolone] a long time ago. It was a very good drug for strength and made me feel pumped. It did not bloat me. I did not crash coming off of it either. I had no gyno problems on it.”

DHT: Does it tell us anything useful about STS-646?

In chemical lingo STS-646 is known as 17alpha-methyldihydrotestosterone, or 17alpha-methyl-DHT. Because it has an ‘alkyl’ group at the 17 position in the molecule (specifically, a methyl, or CH3, group), it may also be classified as a ‘Class 3’ anabolic-androgenic steroid. In case you’re interested, this class also includes oxymetholone, stanazolol, methandrostenolone and 17-alpha-methyltestosterone. The addition of the alkyl group to the carbon atom at the 17 position is thought to drastically reduce the speed of those biochemical reactions which normally act to reduce the drug’s activity when taken orally.

Many of you may be quite familiar with DHT. You may have even come to despise it. Your body converts testosterone into a variety of compounds all day long, one of them being DHT. Another is estradiol, the most potent estrogen. Hormones like testosterone, estradiol and DHT transmit biological signals by fitting into specific receptors found inside the target cell (e.g., a muscle fiber). This is somewhat like how a key fits into a lock. The consensus scientific opinion is that testosterone and DHT transmit their signals via the same receptor, known as the androgen receptor, or AR.

As far as its attraction for the AR is concerned, DHT is about 3 to 4 times ‘stickier’ than testosterone itself. Thus, once it fits itself into the AR, DHT tends to reside there quite a bit longer. The result is that it can transmit ‘louder’ biological signals.

What kind of signals does DHT send? DHT is often blamed for the ‘androgenic’ effects of anabolic-androgenic steroids, some of which are viewed with disdain: hair loss, acne, aggression, cardiovascular effects (e.g., hypertension, proatherogenic events), prostate enlargement, and so on.

Of particular interest to the bodybuilder is that DHT is typically regarded as being rather weak in the muscle-building department. However, like the purported link between DHT and prostate disease, among others, the issue of whether DHT can build muscle or not seems to be far from conclusive. Bhasin (1998) relates:

“We do not know if the anabolic effects of testosterone require its conversion to dihydrotestosterone by 5-alpha-reductase. Although there is a small amount of 5-alpha-reductase activity within the muscle, 5-alpha reduction does not appear to be obligatory for mediating androgen effects on the muscle. For instance, patients with benign prostatic hypertrophy who have been treated with the 5- alpha-reductase inhibitor finasteride do not experience muscle wasting. Similarly, patients with congenital deficiency of 5-alpha reductase enzyme have normal muscle mass.”

[Author’s note: Patients with a deficiency of so-called ‘type II’ 5-alpha reductase can still have detectable levels of circulating DHT, possibly the result of production by the type I form of the enzyme. Also, although muscle is thought to express relatively little 5-alpha reductase activity, it does contain a substantial amount of DHT, presumably supplied by diffusion from the bloodstream. Finally, when prostate cancer patients undergo androgen deprivation therapy (characterized by drastically reduced levels of testosterone + DHT), they experience muscle wasting.]

If in fact DHT is a poor muscle-builder, this may have something to do with (forgive me here) 3-alpha-hydroxysteroid oxidoreductase. This enzyme, which is believed to occur in muscle tissue, can convert DHT into 3-alpha androstanediol. The latter is thought to show little or no ‘stickiness’ for the AR. In other words, any flaming androgen (i.e., DHT) entering your muscle fibers is more likely to be doused with water (i.e., inactivated by 3-alpha-hydroxysteroid oxidoreductase) than it is to attach itself to the AR and transmit a muscle-building smoke signal. Or so the theory goes…

[39th/Lexington]

call me crazy but isnt m5aa the same thing or am I missing something.

[1fast400]

This is Methyl-DHT

[chan_ho_nam]

Ewwww.....DHT.....

[1fast400]

It should make you real hard and give some good preworkout agression

[corpsedub]

i'll stick with M5AA

[sicosico]

isn't methyl dht supposed to be illegal to sell ?

[damned.]

The site doenst work?

[brodus]

I searched and can find nothing about "Giant Nutrition," although I am well aware of what M-DHT is, and also aware that this was one of Sledge's "pipeline ideas." Any further info or retail information would be appreciated...I just hope it comes bundled with Propecia, AA, Sprio, and Nizoral 2%.

[dsade]

I got to try out an advance bottle and, as someone very prone to prostate issues and hairloss, there was no aggravation AT ALL.

The aggression is much more intense than M5-aa.

[pu12en12g]

It should make you real hard and give some good preworkout agression

Will you have this on your site at all ?

[39th/Lexington]

interesting, when will ***** be carrying this.

also is methyl-dht a CIII substance??


Also, sounds better as it doesnt need to convert first.

[Sldgehmr]

Its definetly stronger then M5AA, obviously and you wont find much better for hardness and aggression.

This really is going to be for the hardcore, not everyone will want to try and its probably better that way.

[39th/Lexington]

Will you have this on your site at all ?

I heard primaforce is making it which 1 fast carries. How long until they have it out?


I really like the primaforce line, they carry simple supps that work at an affordable price. I have only read one complaint of a guy who said their glutamine was nasty.

[39th/Lexington]

Its definetly stronger then M5AA, obviously and you wont find much better for hardness and aggression.

when will you have it, and is this your last prosteroids you are getting before the ban.


I am interested in trying your new ala product, when will other retailers carry it.

THIS IS MESTANOLONE. It is illegal to sell. It is a C-III. You will go to jail for selling or buying it if you are caught.

Certain states have it as a C-III. I am not going to look through all of them but I think California is one of them for sure.

If it is legal to sell, it will be one heck of a product.

Wonder why GIANT waited so long to sell it?

Primaforce will have this out next week we hope. I have yet to inform BB.com of it because I do not have it in my warehouse and it won't be ready to ship until mid-next week at the earliest. In fact, I'm amazed anyone knows.

[LIFT2beHUGE]

Does this not scare anyone? Poor prostate, poor hair follicles. Don't get me wrong the pros are kick ass, but the cons of this could be bad. Has there been any testing done to see how this affects the prostate bc I am definitely interested in it just don't want to start prostate probs any earlier than I have to.

Not even remotely like Ephedrine - more like you want to finish your set, and then start tearing **** off of the walls.

[fadi]

It is too expensive for what it offers. That is assuming the benefits are the same as M5AA. 90 pill bottle for $45 (retail $90). I think each pill is 12.5mg, and one of the reviewers stated it may work as mass builder at 100mg?
