DT- what i do know is this. if you reach climax and dont let it go, then this drug will allow you to go on and on...you actually have to take a rest, and re-start, if you will- to get the sensation of climax again....its not like the effects of GHB where it will not allow climax,(until the next day) it does very much so, but you have to literally start over...this is from my experience.
