im a fan of vapor, but like jess posted, u gotta up ur intake a lil after a while... i went from one to two, i never made it to three before i ran out tho... also, its very important to take it on an empty stomach or its worthless...ive also tried
superpump, i didnt like it cuz i like to sleep at night...haha..but i got sick for a couple of weeks, bought some more vapor, and now that i took about 3 weeks off it, its giving me good pumps and energy like the first time i took it.. and from what im seeing at the local gnc, all bsn products went up cuz theyre sponsoring ufc or w/e... im loving syn-6 tho...
