Finasteride / Dutasteride vs Melanotan II
Both are used for sexual health. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Finasteride / Dutasteride | Melanotan II | |
|---|---|---|
| Human evidence | ★★★★★ | ★★☆☆☆ |
| Legal status | FDA Approved | Not Approved |
| How it works | Inhibit 5α-reductase (SRD5A2), blocking testosterone→DHT conversion. DHT drives male-pattern hair loss and prostate growth. Finasteride hits type II; dutasteride hits I and II. | Non-selective melanocortin agonist (MC1R tanning + MC4R libido/appetite); darkens skin and raises libido. |
| In plain English | Testosterone gets converted into a stronger cousin (DHT) that kills scalp follicles. These drugs block that conversion to save hair — but for a minority, lowering DHT dents libido/mood ("post-finasteride" concerns). | Tans skin and boosts libido by hitting melanocortin receptors — but it also darkens moles and its long-term safety (including melanoma concern) is unknown. |
| Bottom line | Most effective hair-loss drug; weigh the sexual-side-effect risk honestly. | Effective tanning/libido effect, real unresolved safety questions. |
| Availability | Available over the counter | Not widely approved |
