I ran two bottles. Started with suggested dose and upped it to 4 caps a day. The bottles went so quick. I think ronnie was running higher doses; Ive heard 600mg somewhere, but maybe even higher than that.... Like i said i was doing four prebed, which is 400mg. I didnt notice anything tangible. At 35 a bottle for 60 caps its not worth it imo.
Also from what ive read: 2 for general health benefits, 4 for recomp, 6 for anabolic growth.
Definitely has been recommended by some reputable bodybuilders: Phil Hernon, Bios3, Ronnie and many more.
