Good heavens man. You’re going straight for the jugular. If you haven’t used a pre in 8 years why would you wanna jump straight to an amphetamine analogue or moda? Craze had an methamphetamine analogue in it, NaDepea. The only thing close to that is Excelsior. It definitely has some sort of amphetamine or even Modafanil in it. Although the batches and even individual tubs vary wildly in potency. Also, I’ve found Excelsior to be potentially addictive. If you can’t stick to using 2-3 times a week at most, I wouldn’t touch it. I’ve also talked to 2 people have had mini strokes from abusing it. The 1,3 DMAA Pre’s now are crap compared the old ones. Dark Labs Pro Crack or God Status Labz Krak’n are probably the closest you’re gonna get to something decent. I personally think the DMHA ones these days are better. It sounds like you want some Adderall or Modafanil. Maybe get a prescription, not a pre workout if that’s the case. Not trying to be an ass just saying it how it is. You’re not gonna find what you want through a pre workout. Plus who knows where these pre workout companies are sourcing their stims from. Especially excelsior. Likely some cheap crap off of Alibaba especially since some batches have been great and others trash. I don’t trust it personally
