Human Growth Hormone (Somatropin) vs Vitamin C (Ascorbate)
Both are used for skin & hair. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Human Growth Hormone (Somatropin) | Vitamin C (Ascorbate) | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★★☆ |
| Legal status | Prescription, Controlled | OTC Supplement |
| How it works | Recombinant GH acts directly on the GH receptor (GHR) → JAK2/STAT5 signalling → hepatic IGF-1, driving lipolysis, protein synthesis, and collagen turnover. | Cofactor for prolyl/lysyl hydroxylases (P4HA1) in collagen synthesis, for dopamine-β-hydroxylase (noradrenaline), and a water-phase antioxidant regenerating vitamin E. |
| In plain English | 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. | Your body literally can't build collagen without it, and it mops up free radicals. Take it with collagen for tendons. |
| Bottom line | Legitimate for diagnosed deficiency; high-risk off-label. | — |
| Availability | Controlled substance | Available over the counter |
Which is better for skin & hair?
Both carry a comparable human-evidence rating (★★★★☆). Choose on mechanism fit, side-effects, availability and cost rather than evidence strength alone — they work through different mechanisms.
