I saw a paper raising a safety issue about involvement of mTOR with high-protein diets as increasing risk for atherosclerosis. Is there a possible safety hazard in the use of Advanced Muscle Plus along with Advanced Amino Formula?

While the case can be raised from a scientific perspective, like many conjectures and hypothetical possibilities it is not necessarily the case that the scientists are right. As history teaches, science is usually wrong, again and again and again. So this is something you need not worry about.
