So, I bought some Dark Energy and it's pretty wild. It says on the bottle it's a "research chemical and not for human consumption" which is hilarious. I don't know how they get away with selling it like that.
I also watched the Fitness News dude on YT, he talks about one preworkout called IMPERIAL NUTRITION EXCELSIOR and he thinks it must be spiked with some kind of amphetamine or amphetamine analog that's not listed on the label, like the old CRAZE fiasco. I might give it a try just for kicks.
But I was also wondering if there are any fat burners out there with the stims still in them. If anyone knows or can recommend one, let me know. I had an old bottle of Condemned ARSYN and it had DMHA and Noopept in it. I noticed they still sell it, but they took the Noopept out. But I bought some Noopept from Nootropics Depot and it feels great with DMHA and seems to have a synergistic effect for energy.
