In healthy adult males the effects of YK-11 on muscle building quality are likely to be submaximal because it is a partial agonist on the androgen receptor and so a healthy male may experience reductions muscle strength and hardness while a female may experience improvements. However the ability of Yk-11 to increase follistatin levels compared to DHT and other steroids is what makes it novel. However no pre-clinical, clinical data exists to confirm its therapeutic significance if any.
