||(powder / crystals)
I went into this blind, no info exists on the use of this chemical online at this point. I had previous experience with ethylphenidate, and had a small amount of HDMP-28. It's legal at the moment, or at least unscheduled everywhere.
I put 20 mg in a capsule, and 20mg sugar in another. I mixed them up so I wouldn't know which I was taking (to lessen placebo effect), I ended up taking the real thing the first time. It is a triple-uptake inhibitor that has roughly 1/4 potency of cocaine and maybe double duration.
0:00 I take 20mg in a gel capsule.
0:30 Slight feeling of elevation, and stimulation. I can tell I didn't take the placebo.
1:00 The high feels more similar to cut cocaine than Ethyphenidate, but notably less pronounced euphoria and could think clearly. Also can tell on the peak, and will come down. Lights are more bright, conversation is easy with a friend who was sitting in on me, and feel general lift in mood.
1:30 Felt like it was in general a positive experience, that I personally do not want to repeat. I do not like or take cocaine though, although I have used pure coke 2 separate times.
2:00 Still slight stimulation, I took a small dose so effects weren't 'full blown'. I drink lots of water throughout to be nice to my kidneys and liver.
4:00 About back to baseline.
Summary: No interest in re-dosing at all, and don't plan on using the rest. No major comedown. I didn't mix this with alcohol, which could majorly affect how this particular substance affects you. I also took it orally, which could affect my experience.
