smash AMF. I bought a tub to try since people spoke quite highly of it. Its ok, definitely gives some focus but doesn't feel insane or anything. What is insane is that it gives me symptoms of high blood pressure unless I pair it with a pump formula, in which case its decent. I don't think I'll be buying another tub.
>all time favorite
Excelsior/Thermal Spark. Retardedly expensive and you have to order from Predator nutrition overseas, but its definitely the best pre on the market still even today. I'm convinced the only reason you can buy it from Predator is to skirt FDA regulations in the US. Its obviously spiked with something but I don't mind it. The energy feels clean, long lasting, and gives me insane tunnel vision which I prefer over cracked out energy.
>Other pres I've tried
Crack, Crack Gold, Crack Primal, Dark Energy, OG Mesomorph with dmaa, mr hyde (good daily driver), god of rage, re1gn, and probably others I've forgotten. Needless to say I've tried a lot.
