I can't speak to actual meth, as I've never had the pleasure of buying crank from a biker and smoking it with a tatted-up single mother of 4 named something like Skyy that you'd promise to take away from her stripper life (just guessing that's how it works), but I will say it blew Adderall and Excelsior out of the water.
I would hit a scoop of it (it was the exact same sized scoop and tub that Excelsior came in...hmm...) and then lift for, no joke, like 2.5 hours. I would get lost in my music and just obliterate workouts. I had severe knee surgery in like 2012 and lost all gains imaginable. When I was able to bend my knee again, and with the power of Craze, I put on 40 pounds of muscle in less than a year. I would just take this ****, lift like an animal, and then go home and be like "I can't wait to do this again". It was the best of times.
And you could just order this **** from bodybuilding.com or go to GNC and get it for less than 50 bucks. Dear God, take me back to the early 2010's.
