I've ran a shitload of preworkouts. Had Controlled Labs send me White Flood Reborn to do sponsored logs for them, test ran Ergogenix Ergoblast, did a sponsored log for C4, fucked with ProSupps Mr Hyde, etcetc. I've tested all the most recognize preworkouts you can think of and Komodo Katana is far and away the best and it's on sale for 26.99 here until Monday.
If you're looking for a PWO, give it a go. Cheap af right now.
