A gonadotropin studied for testicular function, fertility, and hormonal axis research.
In the literature, HCG appears most often in work focused on hormone support, fertility and testosterone. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.
HCG is catalogued here under powder peptides. Coverage of this compound varies in quality and depth, and much of it remains early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.

Gonadorelin is a synthetic peptide identical to GnRH, which regulates the hypothalamic-pituitary-gonadal axis and hormone production. Researchers study its applications in fertility, hormone optimization, and maintaining testicular function.
Human menopausal gonadotropin, studied in fertility and reproductive hormone research.
A reproductive-axis peptide studied for libido, testosterone signaling, and fertility.
