aye. along with steroids its one of the few supps that has concrete evidence supporting.

didn't feel like a serious game changer when I was taking big doses, but I felt like it did a good job at making me present at the gym. Like I didn't have "slow" days working out, or off-days, or days where I roll up and feel 'blah' and slack on the workout.

I'm not sure it let me actually push more iron or run faster in an absolute sense, but it ensured got there and went hard.

by comparison I had friends on the gear, and they were visibly more muscular in weeks, and started lifting serious metal not long after. "die young, die strong, dianabol"
