Saw lot of youtuber take them 5gram daily

I read it not really have ball shrinking side effect?? Dk if true. but help muscle recover faster and performance better??

any advance user tried them, how is the experience?

It's not aas. Doubt it's gonna have ball shirking effect.

And I don't really feel much different when on vs off. Maybe it's just me. Rather save the money for Preworkout or caffeine supps
