Okay so this was years ago so I forget exactly how long I ran it but it was between 4-8 weeks. So yk11 is a steroidal sarm that looks like a dht and can behave like one but it is actually a 19 nor believe it or not. If you have read anywhere that it's a dht, that's wrong because all dht molecules have a certain molecule and yk11 lacks that single molecule(I forget off the top of my head which molecule, it has to do with the 5a one I think because dhts don't convert, could be wrong on this don't feel like looking) But here's where it gets confusing, it's a 19 nor but not a 19 nor steroid. Recently I have seen this compound surface again and a lot are asking questions so I decided to make this to give people some idea where to start because info on this is very limited and I think I might be 1 of the last people on this forum that has run test and sarm cycles and knows about them because I see people mixing sarm and steroid cycles. You don't mix regular steroids with sarms because they won't really be effective cuz the sarm is gonna hog the receptor. so here's some knowledge. Sarms have much higher binding affinity for the androgen receptor than all regular roids besides tren, tren actually behaves kinda like a sarm in the body because its tissue selectivity and high binding affinity. Now I personally don't even know if yk11 is truly a sarm or not. But for sarms sake I'm gonna use the same idea towards it. By not going over 300mg of test a week because sarms hog the receptors so if your running high test with sarms it's just gonna be converting into estrogen. So any other sarm do not go over 300mg, with yk11 if you want to experiment a little with test doses go ahead because this compound can cause joint pain so people might want that extra estrogen. Me, I am high converter as it is so the 300mg was good enough for me. But for most people that I know from the past that ran a lot of these types of cycles all said the same thing no higher than 300 but a lot said just take like 200-250. So there's no ester on yk11 so I recommend doing it 2x a day, some only take it once a day. Up to you really. But the only lab test they did in mice and cells showed yk11 having a extremely short half life, this doesn't always translate to people but it's something to base it off of. Speaking of the lab tests, they infected mice with e coli, and gave half the mice yk11 and the ones that got the yk11 all survived longer than the ones without it. Strange fact but I thought I would add it. And in cells it showed to have the myostatin lowering. But again that doesn't always carry over to people. But I feel like it definitely affects myostatin or follistatin or some kind of mechanism to give crazy strength and gains. Now a lot of yk11 is faked. All the.liver toxicity of yk11 is all lies, the liver toxicity of it came from places selling superdrol and prohormones as yk11 because orally yk11 doesn't do much and yk11 is more expenaive. So if you got some oral yk11 that blew you away, it was most likely something else. Now getting on, I suggest starting low some might even want to start at 10mg for the first week then adjust accordingly. I have went higher than 40mg a day but at that point I was getting flat. It was probably burning a lot of carbs. Now I forget exactly how I felt in the first week or 2 but it does hit fast because no ester. I would do 1 Im shot in the morning with the test p and then 1 subq evening time. The strength was crazy so be careful you don't tear muscle or tendons. I did 4 total cycles of this. First 2 were amazing. 3rd was just okay and 4th didn't really do.anything. so I don't know if it can only lower your myo a certain amount and then it stops working or what the case was cuz I know I had legit stuff for all the cycles. I like to compare it to bulking/strength boost of anadrol, well more strength than anadrol but with cutting oh like winny/tren but these cycles I didn't have any negative side effects besides maybe the joint pain but I kinda always have that so it was a minor inconvience. Different doses can make it lean more 1 way depending on your goals but you have to see what works for you. This is a mystery compound so I don't know what the case is. Any questions feel free to ask. I hope I didn't forget anything. I apologize if anything was auto corrected and changed cuz it keeps changing words on me but I tried to switch everything it auto corrceted. This was my experience.
