Idiosyncratic response to MPA - am I alone in this?

[gratefulresearcher]

At small doses <20mg this stuff makes me feel nauseous, lethargic, slight headache and no stimulation. At moderately increased dose the same but with (not unpleasant) tingling in body (random locations, infrequent). Stupidly ordered a load more as thought I must have been sent something else by mistake but this ones destined for the bin. And I've quite a lot of research experience over the years so this one's really taken me by surprise.

My guess would be it's not methiopropamine,you should definitely feel stimulant effects at dosages 20 mg.'s and up, even with a stim tolerance. I've felt definite stimulant effects from as little as 5 mg.'s intranasal. That or your body just doesn't process MPA normally, but that's unlikely. Also could have been heavily cut or another lesser stimulant they're passing off as MPA. Really know way to tell without getting it tested.

I did wonder but then sourced smaller amounts from generally reputable sources that supplied other stuff as described, leading me to doubt it. But it is strange certainly and I wondered if anyone else had experienced the same.
