Sexual Health Peptides

Trans-clomiphene

The active trans-isomer of clomiphene citrate that acts as a selective estrogen receptor modulator (SERM). Blocks pituitary estrogen receptors to increase LH/FSH production and downstream testosterone synthesis. Studied for male hypogonadism as an alternative to TRT that preserves fertility and natural testosterone production.

GnRH

A synthetic form of endogenous GnRH that stimulates the pituitary to release LH and FSH. Widely used in TRT protocols to maintain testicular size and function.

Human Menopausal Gonadotropin

A urinary-derived combination of LH and FSH used clinically for fertility treatment and in TRT protocols for testicular stimulation and spermatogenesis support.

Metastin 45-54

A 10-amino acid neuropeptide that acts as the master regulator of the reproductive hormonal axis by stimulating GnRH release. Supports testosterone, libido, fertility, and sexual health.

Ovarian peptide bioregulator

A peptide bioregulator targeting ovarian tissue from the Khavinson series. Studied for female reproductive aging, premature ovarian insufficiency, menopause symptom management, and ovarian reserve support. Normalizes follicular cell function and ovarian hormone synthesis.

Love hormone

A 9-amino acid neuropeptide produced in the hypothalamus that plays a central role in social bonding, trust, reproduction, and wound healing. Studied for autism spectrum disorder, anxiety, social behavior, and relationship enhancement.

Bremelanotide

An FDA-approved melanocortin agonist for hypoactive sexual desire disorder (HSDD) in premenopausal women. Acts centrally via the CNS to increase sexual desire and arousal in both men and women.

Testes peptide bioregulator

A tetrapeptide (Lys-Glu-Asp-Glu estimated) testes-targeting bioregulator from the Khavinson series. Normalizes Leydig cell function, testosterone synthesis, and testicular morphology. Used in male reproductive aging, hypogonadism research, and testosterone support protocols.
