Jesli rzeczywiscie to takie cudo i okaze sie nie byc jakies mega toksyczne to przeciez to bedzie bajka :D

Importantly, it should be noted that IPH is ultimately metabolized to the same major albeit pharmacologically inactive (Patrick et al, 1981) metabolite as MPH, i.e., ritalinic acid, and hence IPH will not be subject to yielding any uncharacterized metabolites that might otherwise be a source of concern due to a potential to produce adverse effects and/or toxicities. IPH was also noted to be a poor substrate of transesterification reactions known to be catalyzed by hCES 1.

Isopropylphenidate - An Ester Homolog of Methylphenidate with Sustained and Selective Dopaminergic Activity and Reduced Drug Interaction Liability

Results: IPH displayed unique pharmacological characteristics including greater DAT than NET binding and cellular uptake
activity, and greater resistance to hydrolysis and transesterification via carboxylesterase 1 relative to MPH. Further, sustained
psychostimulant properties offer the prospect of an enhanced duration of action.

I'm this guy's gf, we're trying it together. No burn like eph, it was really surprising. slight euphoria, feeling awake and alert but more relaxed, unlike on eph where i feel on edge most of the time
