🧬 Best Peptides for Fertility & Hormones
Peptides for reproductive health support hormone optimization, libido, and fertility markers in both men and women. They work through GnRH signaling, LH/FSH modulation, and melanocortin pathways to restore hormonal balance naturally. These are among the most well-studied peptides with several holding FDA approval for clinical use.
Kisspeptin-10
Upstream signaling peptide that nudges your brain to naturally produce more testosterone and reproductive hormones without shutting down endogenous production.
Gonadorelin
Synthetic GnRH that triggers LH and FSH release from the pituitary. Commonly used to keep testes functioning during testosterone replacement therapy.
Triptorelin
GnRH agonist for PCT. A single low dose (100 mcg) spikes LH and FSH to restart natural testosterone production. Continuous high-dose use causes the opposite effect.
PT-141 (Bremelanotide)
Boosts sexual desire through melanocortin receptors in the brain, not blood vessels. FDA-approved as Vyleesi for hypoactive sexual desire disorder in premenopausal women.
Melanotan II
Primes skin to produce more melanin, reducing UV exposure needed to tan. Also suppresses appetite and boosts libido. Some UV still required to trigger darkening.
