L Arginine - An essential amino acid that benefits your body by increasing growth hormone levels and nitric oxide production, thus resulting in improved muscle mass, strength and athletic performance. L Arginine is simply a building block for the synthesis of new proteins and is a must in your supplement repertoire. But how does it fair with it's modified friend AAKG?
Arginine Alpha Ketoglutarate - AAKG is a modified form of L Arginine which has been bonded with alpha ketoglutarate (a glutamine precursor) to promote the same effects as above. So, L Arginine is the base and without it you wouldn't have AAKG however what is unique is that it is an intermediary into the Krebs cycle which basically means it contributes to ATP, your bodies main energy source!
Which is best? I will leave that up to you to decide?
