I've taken Agmatine for 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 Agmatine. Pumps are more furious and vascularity is increasing every workout and endurance 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?
