I just started to workout again, its been like 3 years. I want to help jump start my results so i purchased some supplements. I purchased the Universal Animal brands and im "stacking" them; Animal Pak, Animal Stak 2 and Animal Cuts. Has anyone ever used this brand? I also purchased a bottle of L-Glutamine. From what i read it helps preserve your muscles as well as assist with your metabolism. questions? concerns? comments? thanks
