The Inspiration Behind Amino Rx

Frustrated by ineffective muscle-building supplements on the market, Dr. Seltzer developed Amino Rx to meet his personal and professional standards. He explains:

“I originally designed this product for me—a 48-year-old lifetime natural weight lifter looking to maximize muscle mass. I wasn’t satisfied with other products, so I designed one to meet my needs. I drink it before and during every weight workout and am getting results like I did in my 20s.”
