The peptide enhances expression of key transcription factors including Lhx2 and Sox9 essential for hair follicle stem cell maintenance and activation while modulating Wnt/-catenin signalinga critical pathway for hair follicle morphogenesis and cyclingwith treated follicles showing enhanced -catenin nuclear localization and increased Wnt target gene expression

Athletes face suspension, disqualification, or other penalties if the peptide is detected in drug testing
