i would just use it before sex. do an internet search, there are lots f places that sell it. It can also be an effective fat burner taken orally before exercise on an empty stomach.
whats the difference in the two, which is better for sex. is the hcl more powerful, i'm using yohimbe standardized right now and getting good results at 18mg. iseen alot of yohimbe stuff, like yohimbe 2000, that seems like alot.
