Doomsday was awesome for me. I never tried hardcore. Doomsday was slight euphoria,it made me chill but gave me enough urge to go to gym, and lifting weights was easy. Loved it.

What's fascinating to me: even today, after all this heavy abuse and such, a single scoop of Doomsday or a similar Pre. is usually more than enough to help me get the wanted amount of additional focus (as a nootropic) or energy (at the gym) or whatever it is i desire.

Now that Excelsior and its family (Doomsday Hardcore, Hydrazine, etc.) are basically dead I am scouring the internet for anything remotely similar without beta or Y.

I’ve recently got Mr white , Doomsday & had a sample of Goddamn fury sample I’d opt for Goddamn Fury if you want the biggest hitter.

KJ Doomsday I have to do another run because I suspect my tolerance was fucked up when I ran it the first time.

"It came with no real drawbacks but the overall feeling felt more so like a decent energy experience with a side of something special."
