I frequent a totally free sex board(for anyone that wants to know its called www.nudeafrica.com-all races post pics and shoot the shit-but if ur looking for a spanish or white women they usually post in the in search of side,the rest is usually black)and in the anything goes section i read someone talking about that NO2 or Largenine.They said its not only good for people with weak erections-body builders use it to produce more blood flow to every part of the body.My question is-----is it safe,does it have side effects,can smokers take this stuff?II work out alot pe and other exercises and anything i can get my hands on to help i will do,anyone here have first hand knowledge of the stuff?
