Well. I am no newbie either, I have been pilling for 4 years and I have tried the lot. I and my friends all agree that after the 2nd pill you are definately fucked but not anywhere near feeling like you do at the 1.5 hour point on your first. I have tried all of this, all I get is the most amazingly distressing Monster E face you have ever seen, along with serious muscle problems later. No I haven't tried 5HTP, but I know people who have and do. They seem to think that it doesn't last as well as people rave on about. Heard of 'placebo'?
Lastly, post loading has nothing to do with your peak...hence 'POST'...that was kind of a clutch at a straw, not to mention constant dosage of MDMA. As I have said before, your serotonin runs out after about 4 or 5 hours, and no dose of 5HTP is going to produce enough serotonin, because the body can only convert it at a certain rate. It's not as if it immediately becomes a rush of serotonin in your brain. You don't need to be a genius to realise this.
Anyway, i'm not attacking you, just dispelling the 'back when I was a lad, we peaked for 48 hours because we could get 5 gams of pure MDMA and attach it to a drip which we carried around with us to barn dances....blah' myths that seem to crop up.
be smiley,
