- increase muscle grow
- strengthen bones
YK11 is one of the strongest sarm on the market. There have not been much studies done about it but believing most people it can build lean muscle mass quickly and improve bone health.
There is not much known about side effects but reports of higher aggression and suppressing natural hormone production is occurring , especially at higher doses.
So a PCT is recommended.
If you are interested in doing research and experiments with sarms make sure you buy your sarms from the right seller. For me , I buy my sarms from SARMXXL.com . They have double test rapports available and their quality is superb! Also their formula with XXL products makes it very cheap.
