I tried Both:

-YK-11: 12mg ED for 4 weeks: feeling pumped and full all day long, no crazy evolution, but great feeling, kinda feels youre on medium dosage of T-bol

-Follistatin-344: 100mcg ED (intra-muscular pre-workout) for 4 weeks, crazy pumps like IGF-LR3. The weight stayed the same, insane vascularity and fullness, the body fat dropped, you see your body changing week after week.


Follistatin at high dosage would give crazy results, but it would very unaffordable...
