THE TESTOSTERONE RESTORER
A-17 Peptide; Testicular Bioregulator
Testoluten is a testis-derived bioregulator peptide that supports testosterone production and sperm health. It works by stimulating gene expression in Leydig and Sertoli cells, promoting steroidogenesis and spermatogenesis. It's used for andropause, subfertility, recovery after steroid use, and age-related testicular decline.
