I've takenfor a while and I'm no really impressed with its pump factor. I think pound for pound TAA blows it away. What I've gain with TAA is remarkable compared to . Pumps are more furious and vascularity is increasing every workout and is non stop and I'm having a hard time stopping my work out. Funny thing to is my strength is increasing every workout. I'm really enjoying this supplement. Anybody else reaping these rewards?
