Finasteride / Dutasteride vs Human Growth Hormone (Somatropin)
Both are used for skin & hair. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Finasteride / Dutasteride | Human Growth Hormone (Somatropin) | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★☆ |
| Legal status | FDA Approved | Prescription, Controlled |
| 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. | Recombinant GH acts directly on the GH receptor (GHR) → JAK2/STAT5 signalling → hepatic IGF-1, driving lipolysis, protein synthesis, and collagen turnover. |
| 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 actual hormone, injected — rather than coaxing your pituitary to make more. Powerful for genuine deficiency; misused for physique it carries real metabolic and growth risks. |
| Bottom line | Most effective hair-loss drug; weigh the sexual-side-effect risk honestly. | Legitimate for diagnosed deficiency; high-risk off-label. |
| Availability | Available over the counter | Controlled substance |
