The person credited as the "father" of modern supplementation as we know it today is someone that a LOT of people have never heard of; RHEO H. BLAIR.
(I bet Tim and TC know of him!)
All the great bodybuilders of the 50's, 60's and 70's (Arnold,Frank Zane, Larry Scott, etc.) followed this guy's advice and got in the biggest and best shape of their lives. He had the secret of achieving steroid-like results without drugs.
Blair rationalized that the highest quality protein in terms of supporting human growth and well-being would be found closer to home - in mother's milk. It is the food that has been honed by millions of years of evolution to nourish newborns and carry them through their most rapid period of growth. Plus, enzymes found in milk, such as colostrum and lactoferrin, were believed to have powerful immune system-enhancing properties.
His famous protein powder was based on the amino acid ratios in mothers milk.
Forget Arnold! Arnold went to HIM for advice!
