PT-141 and Melanotan-2 are related peptides that both act on melanocortin receptors. PT-141 was actually developed from Melanotan-2 research when sexual function effects were observed. PT-141 has been refined to focus primarily on sexual function, while Melanotan-2 retains broader effects including tanning and appetite suppression alongside sexual effects.
| Category | Pt 141 | Melanotan 2 |
|---|---|---|
| Primary Research Use | Sexual function | Tanning/pigmentation |
| Secondary Effects | Minimal tanning | Sexual function, appetite |
| Receptor Selectivity | More selective (MC3R/MC4R) | Broader melanocortin activity |
| FDA Status | Approved (Vyleesi) | Research only |
| Price Range | From $44.99 | From $34.99 |
| Purity | ≥99% HPLC | ≥99% HPLC |
More selective and FDA approved for this indication
Primary research application is melanogenesis
FDA approved with extensive clinical data
Broader range of melanocortin effects
Yes, PT-141 was developed when researchers noticed sexual function effects in Melanotan-2 studies and worked to create a more selective compound.
Yes, Melanotan-2 research shows sexual function effects, but PT-141 was developed to be more selective for this specific application.
PT-141 is generally considered to have a more focused effect profile since it was developed to be more selective than Melanotan-2.
