Finasteride / Dutasteride vs Melatonin
Both are used for hormones & testosterone. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Finasteride / Dutasteride | Melatonin | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★★ |
| Legal status | FDA Approved | OTC Supplement, Prescription |
| 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. | Pineal hormone binding MT1/MT2 receptors (MTNR1A/MTNR1B) in the suprachiasmatic nucleus — shifts the circadian clock rather than sedating. Most people massively overdose it. |
| 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). | The "it's night" hormone. It re-times your body clock, so it's best for jet lag and late sleep phase, not as a sledgehammer sedative. 0.5 mg works as well as 10 mg with less morning fog. |
| Bottom line | Most effective hair-loss drug; weigh the sexual-side-effect risk honestly. | Overused at 10–20× the effective dose. Start at 0.5 mg. |
| Availability | Available over the counter | Prescription only |
