However, the compound became widely available for routine use in the treatment of B12 deficiency in the early 1950s

WADA Prohibition The World Anti-Doping Agency classifies both peptides as prohibited substances for competitive athletes: Section S2 classification Peptide Hormones, Growth Factors, and Related Substances Prohibited at all times (both in-competition and out-of-competition) No Therapeutic Use Exemptions available not recognized as legitimate medical treatments Performance-enhancing potential acknowledged due to growth hormone secretagogue effects Detection methods under development for anti-doping testing programs WADAs position reflects that these peptides possess clear performance-enhancing properties and lack approved therapeutic applications that would justify medical use exemptions

The peptide consists of 16 amino acids from the C-terminal region of human GH, a section known to influence metabolic and tissue repair processes

In vitro co-immunoprecipitation and fluorescence polarisation assays have investigated the binding affinity of Proxofim for the p53 interaction domain, examining whether the DRI construct competitively displaces endogenous FOXO4 from the FOXO4-p53 complex in senescent fibroblast cultures
