Best peptides for sexual health
Peptides that support libido, erectile function, and sexual performance through neurological and vascular pathways.
What to know
PT-141 (bremelanotide/Vyleesi) is FDA-approved for hypoactive sexual desire disorder in women and used off-label for male sexual dysfunction. It works through melanocortin receptors in the brain — a fundamentally different mechanism than PDE5 inhibitors (Viagra/Cialis). Nausea is the main side effect. GH peptides indirectly support sexual health through improved hormone balance and energy. Kisspeptin is emerging as a research peptide for sexual arousal.
Recommended peptides
PT-141
PT-141 (Bremelanotide) is FDA-approved for hypoactive sexual desire disorder in women. It works through the melanocortin system rather than the vascular system like Viagra.
Kisspeptin
Kisspeptin is a neuropeptide that triggers the release of GnRH, playing a key role in puberty onset and reproductive hormone regulation.
Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that stimulates the pituitary gland to release growth hormone. It is considered the mildest and most selective GHRP with fewer side effects than alternatives.
CJC-1295
CJC-1295
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that extends the half-life of natural GH release. Often combined with ipamorelin for amplified growth hormone output.
