Product Description
USP YK11 CAS 431579-34-9 Myostatin Inhibitor Sarms Natural Supplement 

YK11 (YK-11) is a selective androgen receptor modulator (SARM) originally engineered by Japanese scientists in a medical research facility. SARM's were developed as a milder alternative for anabolic steroids so people could make gains but without the negative side effects associated with steroid use. YK11 (YK-11) in particular has been shown to create extremely similar results compared to anabolic steroids. As a result, bodybuilders adopted its use for their bulking phases. The potency and effectiveness of YK11 (YK-11) is what ultimately made it so popular and it has been widely used until a series of recent events.

2. How YK-11 Works:

In 2011, Yuichiro Kanno of Toho University published the results of an initial study on YK-11, confirming that the rare compound was a SARM.

YK-11 attaches itself to the AR (androgen receptor), but only inducts methods that lead to the traditional side effects of androgens such as growth of body hair and prostate and enhanced aggression - to a restricted degree.
Most SARMS have quite limited androgenic side effects, but frequently only quite few anabolic effects when likened to testosterone. But, this doesn't occur for YK-11 as reported in Biological and Pharmaceutical Bulletin in 2013.

Kanno tested C2C12 muscle cells and not lab animals or humans. It has been discovered that muscle cells produce more anabolic factors if exposed to 500 nmol (nanomoles) YK-11 than if you expose the same muscle cells to 500 nmol DHT.

YK-11 induces muscle cells to make more follistatin (more than DHT does) - a strong myostatin inhibitor. YK-11 works through the androgen receptor.With that said, YK-11 can be as good as testosterone in terms of muscle strengthening, but minus the detrimental side effects.

3. What does YK11 (YK-11) do?

YK11 (YK-11) provides muscle mass and strength gain similar to the anabolic steroid known as dihydrotestosterone and also has the ability to inhibit myostatin. The myostatin inhibition also boosts the presence of follistatin in the body which furthers production of muscle mass even more.

Since SARM's are loosely defined as selective androgen receptor modulators, almost anything with these properties could in fact be called a SARM. A common misconception is that YK11 (YK-11) is a SARM; YK11 is more closely related to a synthetic steroid. YK11 (YK-11) is only a partial androgen receptor agonist and is similar in chemical nomenclature to testosterone and 5-a-dihydrotestosterone which are steroids. The gains in muscle mass and strength are more related to the androgenic properties of the compound rather than the individual triggering of androgen receptors.

4. Dosages and Suggestion:
Recommended maximum dose YK11 is require dosages of 2.0-5.0mg b.i.d. in males and 0.5mg-2mg b.i.d. in females to achieve optimal effects in humans for the noted indications.

5. SARMS dosage, how to use SARMs:
Andarine,S4, Acetamidoxolutamide: 50-75mg total per day
MK-2866 (Ostarine, OSTA-SARMS): 2.5-50mg per day
GW-50, GW-501516, Cardarine, GSK-516: 20mg per day
MK-677 (Nutrobal): 25mg a day
LGD-4033 (Anabolicum): 10mg per day (2mg per day and up to 20mg)
RAD-140: 20-30 milligrams (mg) per day
SR-9009: 20-30mg per day
