YK11 is one of the newest SARMS to be developed, and because of its young age it has never officially passed the preclinical stage of development, and has never been tested on either animals or humans. All of the available evidence/knowledge about it is from the cellular studies and the anecdotal evidence from people using it.

YK11 is one of the strongest SARMs out there, comparable to certain steroids even in its effectiveness. More specifically, YK11 is a powerful Myostatin inhibitor, which is why bodybuilding industry is going crazy over it.

Myostatin is a protein in our body that has genetic predisposition to regulate our muscle growth potential, which basically means that Myostatin limits and reduces our muscle mass, it prevents our muscles from growing bigger. There is an antidote to it, and it’s called Follistatin.

A special kind of protein found in our muscle cells, Follistatin, as an antagonist of Myostatin, binds to Myostatin and inhibits its negative actions on muscle growth. The more Follistatin we have, the weaker the Myostatin is, and the bigger our muscles get.

YK11 increases levels of Follistatin, which is why it has become extremely popular with bodybuilders. Even though officially classified as a SARM, its chemical structure indicates that it could be a steroid as well, which is why I’d call it a hybrid of the two.

YK-11 Benefits

Increased muscle mass is undisputed benefit of YK11, and it is incredible. Compared to every other SARM on the market today, YK11 will give you the biggest muscle gain during a cycle. Increasing Follistatin and blocking Myostatin results in an amazing ability to increase muscle mass and also preserve it while on a cut.

People who take YK11 report incredible strength gains along with the muscle gains. They are able to consistently get stronger week after week and break their bench press, squat and deadlifts by up to 50 pounds each during a cycle.

YK-11 Potential Side Effects

When it comes to side effects, the most commonly reported ones are hair loss and natural testosterone suppression. If you haven’t used any anabolic compounds before and your natural testosterone levels are pretty high, you will have no problem recovering it – your levels will recover completely in the weeks following the YK11 cycle. However if you’re natural testosterone levels are quite off due to regular anabolics administration or improper handling of these and similar compounds that can affect your levels, I would suggest the same approach when it comes to recovering your testosterone levels I suggested with Ligandrol and RAD140. Introduction of HCG from the very beginning of a YK11 cycle, at 500-1000iu per week, is your best and safest option. You’d be able to minimize and perhaps completely avoid any suppression, avoiding the need for PCT, thus preserving your gains even more.

YK11 has the potential to be liver toxic at dosages higher than 30mg a day. I suggest everyone to use an over the counter liver support supplement while on YK11, and limit their cycle to 8 weeks.

YK-11 Dosage & Cycle

There are two approaches based on the anecdotal evidence and personal experience. A short 5 day blast with 50mg a day, for an explosive almost anadrol-like muscle gain kick start, or 10-15mg a day for a cycle duration of 6-8 weeks. YK11 half life is approximately 12 hours, so splitting up your dosage in two is the best way to go about it.

YK-11 Stacking

YK11 is extremely powerful on its own, so stacking it with another weaker SARM would be a waste since the number of androgen receptors in our body is limited, so you’d basically be wasting some of YK11 because it will lose some receptor spots to the other SARM.

YK-11 Legality

As of 2020, YK11 is absolutely legal everywhere to be purchased and used except Australia where you’re not allowed to use this compound without the doctor’s prescription. However, a lot of Australians use YK11 without getting into any kind of legal trouble.

When it comes to competitive sports, YK11 together with other SARMs is listed as a banned substance by almost all anti-doping sports bodies. You should definitely not use it if you are a professional athlete.

Remember, however, that YK11 is only meant for research purposes and isn’t approved for human consumption.

YK-11 Where To Buy

There are many online companies out there that claim to sell SARMs, but you can’t for sure really know whether what you’re buying from them is the real thing until you’ve seen it work on you and given you results. The only online company that I personally trust in, have tried and been extremely happy with when it comes to results is Chemyo. You can check their YK-11 here: CHEMYO

YK-11 Overview

One of the most powerful SARMs, that would better be classified as a half SARM half anabolic steroid. It’s an extremely powerful Myostatin inhibitor that helps your body surpass the genetically limiting muscle building factor, packing a serious muscle mass. It’s very strong, it’s suppressive to natural testosterone and it shouldn’t be stacked with other SARMs. 10-15mg for 6-8 weeks is the sweet spot recommended dosage.
