A few weeks back I bought a couple of pills that were advertised by a friend as MDMA. I hadn't touched any in over 3 months and there was a large group of us going out so I jumped at the opportunity. I am a 21 year old male, weighing just over 10 stone.

T:0 mCPP down the hatch... bad taste... almost sour and bitter at the same time. Not bad if mixed with Gatorade. T:15 Light nausea onset, not unbearable but uncomfortable. Pupils beginning to dilate. Everything seems bright. T:30 Strong nausea, vomiting. There goes a good lunch.

So I got all excited after reading some people describing mCPP + meOPP as a combination capable of producing an mdma type effect. I'm sorry to say that for me the experience contained nothing of what i look for in a good pill.
Having just moved back to Los Angeles after being significantly farther north in the boonies for the past six months, I decided to see one of my good friends, N, that I had not seen since I left. After reminiscing for a bit, we came to the topic of what we were going to do that night.
Everyone seems to be polarized at opposite ends of the spectrum on these drugs. Either you love them to the point of sounding like you're advertising for a legal high online store, or you absolutely loathe them to the point of calling the drugs dirty, poisonous stimulants.
The first time i took 'extacy', it turned out to be mcPP, but im not complaining I finished work at the usual time of 5pm, went to the pub with my new mates from work.
Substance: way to much mcpp Expierence: Second time I think Setting: At home. Gender: Male Age: 17? at the time 22:20 Swallowed a pill containing mCPP with some water to chase it down. The thing gives me a really bitter taste while it didn't even touch my tongue. Ew..Just the way good E should be.
I'll give everyone a brief run down of 10 friends of mine and myself that have tried it within the past two weeks. This is without bias and just the straight facts per what I saw, heard and felt.
McPP 'Overdose' - 300mg ------------------------------- Prologue I originally wanted to dose 100mg. I have 2 bottles of water-dissolved chemicals, each having different potencies: In my bottle of TFMPP, 15mls is one dose, but from my bottle of McPP, 5mls is one dose.
