| Re: Looking for all-natural products backed by clinical studies AS for natural supplements try using arginine for a natural muscle pump. Take 3000mg a day. Try laoding up on amino acids casue they are the building blocks of protein all the way down to the cellular level. HMB is another supplement to add size naturally. Studies show it helped beginners a lot so it might not be right for you. Amino acids are key so if I were you i would hit em hard especially leucine and glutamine. good luck |
