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.
No chemical compound to my knowledge exists that displays follistain stimulating effects like that of YK-11 so no comparison can be made. DHT is known to have effects on the CNS (central nervous system) and so YK-11 may also possess such effects if it can cross the blood brain barrier.
