I really do think the PureCEE has helped GREAT as far as muscular gains, in conjuction with the ISO. I recently started having a Pre/During Workout shake (I train Early AM & take 4 caps purecee pre training + ISO & Gatorade) & had the best leg day of my life the other day. I never go heavy with legs. If I only had a spotter around more, like I use to, I think I'd be able to increase my #'s with both of these products.
The shake also has helped a little with my endurance during the w/o's but I'm always full of energy in the mornings. As with anything, pinpointing ANY one thing has never been easy for me to do ... it sure contributes though
