What is YK-11?
Research compound aggregated from creator and literature mentions. No direct disease-treatment claims are made on this page.
Experts on background and overview · 7 cited mentions
"30 mg YK11 hardness and density and strength-wise is very comparable to Superdrol, especially considering you can run it longer because Superdrol 30 mg per day that's a 2-week love affair... With YK11, you can easily run it 5 to 6 weeks and then your elbows and knees and joints feel toxic"
"Would it be overkill or redundant to add in Superdrol to peak for a photo shoot when I'm already on injectable YK11 30 mg a week? If you're on injectable YK11, you probably are not too unhealthy yet, so you have a little bit of wiggle room."
"YK11 versus Var total comparable dose, and how long would you estimate it's safe to run?... Winstrol crushes your HDL, but YK11 doesn't seem to do that. Doesn't seem to raise the liver enzymes, really minimal effect on serum lipids."

"I got more eye joint pain from 30 milligrams injectable YK11 than 10 milligrams Accutane three times a week. So I ran injectable YK11 at 30 milligrams per day only for four to six weeks."
"600 test, 600 deca, 350 ment, and 150 tren. 210 YK11. That was a great cycle."
"YK11 is a steroid. Classified as a SARM. And you say that SARMs don't work. Well, YK11 is a steroid, you stupid [ __ ] Look at the chemical structure."
"Injectable YK11 is an oil. It's an MCT oil. So, and it's not a peptide. It's an anabolic androgenic steroid. It's classified as a SARM."
What is YK-11 researched for?
Injectable steroidal SARM with potential follistatin elevation; minimal liver/lipid impact making it a 'middle ground' anabolic.
Experts on uses and effects · 2 cited mentions
"I never noticed an immediate benefit from injectable YK11. I did side enhancement with that as well. Didn't notice anything. I just did that subq to get stable levels throughout the day. And then that gave me some hardness, dryness, fullness comparable to superrol and also dry joints to the point I had to stop it."
"YK11 is a nice middle ground to get the anabolism from the steroid itself potentially some folatin increase and uh and no liver change liver enzyme changes or or lipid changes."
