Progenitor has it in liquid suspension. Not injectable but still works like a charm. It gives me the same sides Dexter’s used to (sweats, aggression, and makes me extremely hungry) so I know it’s definitely g2g. Plus, I don’t make my own stuff so I don’t know what’s in it but I swear the stuff tastes like the inside of a fruit gusher, random as hell but it’s better than the normal ethanol-type suspensions!
But I, like you, absolutely loved Dexter’s injectable mtren. If any sources were to brew it up as a stand alone injectable, I know there would be interest.
