Part of her advantage may have been a result of her affiliation with PeptoPro Sports Peptide drink. The athletes from other countries likely consumed protein sports drinks containing amino acids and peptides, the building blocks of protein. They increase insulin secretion, a metabolite that assists transfer of glucose into muscle cells. There, glucose is synthesized into glycogen, which, as an energy source, is depleted in muscles during physical activity.

Regular sports drinks can require 20 hours to restore glycogen levels. Their proteins must first be digested into peptides and amino acids before they are of use to the athlete. However, Olympians and endurance athletes need to recover in less time than casual athletes (approximately 12 hours), since they may need to perform several times daily.
