well in the past i have tried this "herb" and it all depends on your intentions.. i originally tried it as a supplement for weight training it was touted as the next best thing to steriods.. well the only thing i got was a hard on that didn't want to go down.. it makes u very horny and gives u a hardon that will not go away.. this after 2 weeks of taking it twice daily.. did not work for building muscle but gave u the stamina of an 18 yr old.. the current ones like nor-andro and androtestdione (?) also gives the libido a major boost and was more effective in building mass and strength.. however it work too much like a steriod.. agression also increased, irritation, stress, blood pressure and tightness in the chest all from the current nor-andros and androtestdiones.. but Yohimbe great for the sex drive.. it also increased irritation, agression but not as much.. hope this helps..
ps it is readily available even displayed in some stores in Toronto.. hell i was able to get it under the table in every supplement store in ontario just by asking.. but u may have to be a regular customer..
