Description of SARMs YK11
YK-11 is a synthetic, steroidal selective androgen receptor modulator (SARM). It is a gene-selective partial agonist of the androgen receptor (AR) and does not induce the physical interaction between the NTD/AF1 and LBD/AF2 (known as the N/C interaction), which is required for full transactivation of the AR. The drug has anabolic activity in vitro in C2C12 myoblasts and shows greater potency than dihydrotestosterone (DHT) in this regard.
SARMS or selective androgen receptor modulators are well-known for giving the same muscle growth results as anabolic steroids but without the negative side effects that comes with the latter. Japanese scientists are doing an experiment on a new SARM known as YK11 which is said to be the strongest amongst all, even more potent than classic steroids such as DHT. YK11 is believed to be a SARM and produce the effect of myostatin at the same time.
YK11 Anabolic Effects
A lot of SARMS come with a limited androgenic effect but most of the time, this can’t really be compared to that of testosterone. With YK11 this is not the case and it cannot be compared to testosterone at all. Kanno first started by testing the C2C12 muscle cells and he did not do this on animals or humans. He then found out that the muscle cells in the body produce far more anabolic factors if they are exposed to 500nmol, or nannomoles of YK11 when compared to if you exposed them to the same amount of DHT. So what does that mean? It basically means that YK11 actually induces muscle cells, causing them to make more follistatin. This is way more then when compared to DHT which is a very strong myostatin inhibitor. YK11 also works through the androgen receptor as well so this is something else you need to keep in mind when you are using them for the very first time. That being said, YK11 is as good as testosterone when you look at how much strength it can add to your muscles and it doesn’t give you any of the detrimental side effects as well.
YK11 Bodybuilding
SARMS, including the YK11 are very popular in the bodybuilding industry and the main reason for this is because they can help you to gain muscle and lose fat. This is very similar when compared to AAS but the best thing is that they won’t give you any of the nasty side effects. Some of the side effects you would normally experience include high blood pressure, HPTA shutdown, liver damage and more. SARMS don’t give you these effects because they are much more selective in the areas that they target so you can still get the muscle gain and fat loss.
Benefits of YK11 SARMs:
YK11 SARMs dosage reference:
So how much should you be taking every day? If you are looking to experience all of these great benefits then you need to make sure that you take 5mg a day. If you have taken SARMS before or if you are experienced with them then you may be able to take 10mg a day so you can benefit even more so this is something you need to keep in mind when you are taking them and planning your doses.
