4-MAR is my second favorite drug behins MDMA.I think it's a less profitable product. Better, but it doesn't lead to binging (in most people) because of the SERT activity. SERT is also why if has overtones of MDMA) so it doesn't demand hit after hit, day after day.
4MAR and fencamfamine are the best stimulant's I've tried and I've tried all of the more common ones... about a dozen, I think.
Fencamfamine is of particular interest because it has some opiate activity.
Considering how dirt cheap lefetamine is to synthesize, I'm quite surprised that it isn't seen, It is also a stimulant with opioid activity.
Absolutely amazing. Had the opportunity twice in my life to have it both when a chemistry head friend of mine decided to synthesize 2 small batches for personal use and immediate friends.
Each time it took a few months for enough 'taking the dog to the vet' prescriptions to have enough PPA to synthesize even 7-14g.
Such an amazing substance I miss it.
