For what it's worth, yohimbe is a stamina/indurance herb to maintain high energy out-put beyond that of sex, it overrides the hormone that makes men sleepy after sex. It be can very dangerous to combine yohimbe with say ephedra or other stimulants.
There is simply an active ingredient in all these that produces the desired results, it's nitric-oxide, a gas given off during the bodies processing of L-Arginine which also protects the heart. Pure nitric-oxide like Viagra explodes in the body thus the headaches. Stimulants plus nitric-oxide produces whole body hang-overs. But using herbs that buffer and boost body functions work very well plus produce higher semene production.
My favorite is Blue-Rise, 1/3 to 1/2 a pill can be enough for me, if I take 1 whole one I do get a small head-ache. The results can last for more than a day in fact I take 1/2 the day before. I've only found them at Heartsong, they have a small store and these work better than any i've ever tried which has been several including viagra, plus they are cheep Heartsong gets them directly from a custom manufacturer. They are only 45.00 for 15 pills and your tool only comes up when you need it too, that is kind of a plus.
