I think a natty would feel the effects more than someone who uses gear. If one is used to feeling say, Dbol kick in I don`t think they will be all that impressed with BA or any other natural (OTC) supplement on the market. It`s the same with Creatine. I don`t really find I feel Creatine kick in, its gradual for me. But when I come off I miss the extra muscle endurance and pump that creatine brings. I didn`t notice it while on because it was gradual and slowly`kicked in`, but when i came off and the effects of creatine went away I missed them.
