You got to question how much is bound for anabolism (muscle building) if this herb actually works. It may aromatize into estrogen. One thing I do know is that finastride actually inhibits the conversion of test into DHT (inhibiting 5-alpha reductase) which gives you more circulating test in your blood. Also prevents hairloss and enlarged prostate.
I would prefer andro to this stuff since you know it works. Andro is not juice though. Nothing compares.
