Sexual Health / Libido
Also known as: libido, sexual function, erectile dysfunction, ED, sex drive, arousal, sexual performance, low libido, sexual desire
Key considerations
- PT-141 (Bremelanotide) works through the central nervous system via melanocortin receptors — it is the only FDA-approved peptide for hypoactive sexual desire disorder
- PT-141 works differently than PDE5 inhibitors (Viagra/Cialis) — it targets desire and arousal at the brain level rather than vascular mechanics
- Nausea is the most common side effect of PT-141, especially at higher doses; starting at 0.5-1mg can minimize this
- MT-2 (Melanotan II) has libido-enhancing effects as a side benefit of its melanocortin activity, but it also causes tanning and has more side effects than PT-141
- GH optimization through CJC/Ipamorelin can indirectly support sexual health by improving energy, body composition, and hormone balance
