What Is YK11?
YK-11 is an Androgen Receptor Modulator.
Although YK-11 does not act as an agonist towards the prostate, it does carry with it a similar effect to causing stress on the liver. This is due to the 4 methyl (CH3) groups in its structure. Supplements like Milk Thistle help aide and mitigate the effects.
Application Of YK11
Research from YK-11 studies suggests it has “anabolic effects on bone mineral density and skeletal muscle mass.”*
“YK11 treatment…induced the expression of follistatin.”*
“Follistatin has emerged as a powerful antagonist of myostatin that can increase muscle mass and strength. Our translational studies show increased muscle size and strength in species ranging from mice to monkeys.”*
These studies suggest, at approximate doses of 5mg, mice and monkeys can see SIGNIFICANT increases in muscle mass.

After one week of 10mg a day, my rat was asked how and the F are you getting so big so quick. Guys this stuff is no joke if you’re like my rat where he can get stronger but muscles get bigger slower. Absolutely amazing supplement for insane muscle gain.

This is a great product. I didn’t expect such solid results. It’s difficult to put in a review how great this stuff is. My research animal began obtaining quality gains within weeks. Give it a day or two and things start getting interesting. The research animal experienced no ostensible effects other than fuller muscles. He also had an increase in his lifts and set performance. He had a dose of 10mg per day. Highly recommended.

I’m a F25. I’ve tried almost all of Rat’s Army products over the course of a year.
I used YK-11 for about six weeks. Originally my husband planned to cycle this, but I decided to give it a go instead. Coming from a female, I will say this is not one of my favorite products, however, it will yield results.
My strength was incredible and I started hitting PRs each week. That said, it left me feeling extremely bloated and sluggish. Even more so than LGD
If you can get past the bloated feelings and appearance, you can make some awesome strength gains with this stuff.

If you’re looking for dry, lean gains, stacking this with RAD 140 is by far the best option. Strength shot through the roof and noticed the visible changes becoming apparent around week 5. Very versatile compound for some serious gains.
