Product Description
(17α,20E)-17,20-[(1-methoxyethylidene)bis-(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester (YK11), which the myogenic differentiation of C2C12 myoblast cells is induced by the novel partial agonist. as well as by.
YK11 is a selective androgen receptor modulator (SARM), which activates AR without the N/C interaction. In this study, we further investigated the mechanism by which YK11 induces myogenic differentiation of C2C12 cells. The induction of key myogenic regulatory factors (MRFs), such as myogenic differentiation factor (MyoD), myogenic factor 5 (Myf5) and myogenin, was more significant in the presence of YK11 than in the presence of DHT. YK11 treatment of C2C12 cells, but not DHT, induced the expression of follistatin (Fst), and the YK11-mediated myogenic differentiation was reversed by anti-Fst antibody.
Myogenic differentiation is in reference to the products ability to block myostatin. Myostatin inhibition has been a really popular movement since the ban of most prohormones as it looks to be a relatively unexplored area for muscle growth and fat loss. There are currently a lot of claims about mystatin inhibition, but not so much factual data on these products. YK11 will have similar affects to DHT (possibly more potent) without the negatives of DHT. What this means is that the product will most likely be suppressive and require a post cycle, but not cycle support. It also won't have androgenic side affects like hair loss, acne, etc. The increase in follistatin caused by YK11 will act as an antagonist to mystatin (it will block myostatin) as well as the anabolic properties of YK11.

Fuction:
It induces muscle cells to make more follistatin which is a strong myostatin inhibitor. Myostatin (also known as differentiation 8, is a myokine (protein) produced by muscle cells that acts on muscle cells to inhibit myogenesis. Myogenesis is muscle cell growth and differentiation. Research through the years show that when you block myostatin, it allows for significantly more muscle mass. So in research myostatin are researched to find cures for muscle diseases.
We expect YK11 to be more potent than SARM LGD in terms of overall growth and feel. At this time, we expect this to be the strongest SARM on the market at a regular dosing. While suppression can occur, we expect this product to have low androgenic properties and can be used by both men and women. From our experience with SARMs, we find there are less losses of on-cycle results than pro-, although typically not as potent. We do expect this product to have similar results as a moderately dosed Halodrol, without the alpha-male / androgenic feelings while on it.
