Recombinant human growth hormone — clinically approved for specific deficiencies, frequently misused for anti-aging. Here’s how it actually works and what responsible access looks like.
Human growth hormone (HGH, somatropin) is a 191-amino-acid recombinant protein produced by DNA technology to match endogenous pituitary growth hormone. It’s sold under brand names including Genotropin, Humatrope, Norditropin, Omnitrope, and Saizen.
HGH is prescription-only in the US and FDA approved for specific indications: adult and pediatric growth hormone deficiency, certain short-stature syndromes, HIV-associated wasting, and short bowel syndrome. Prescribing HGH for anti-aging or athletic enhancement is illegal under federal law.
FDA approved for defined indications. Schedule III controlled (for non-approved uses). WADA prohibited (S2). StackTrax does not sell or facilitate HGH.
Binds GH receptors primarily in the liver and peripheral tissues. Liver response produces IGF-1, which mediates most of the anabolic and metabolic effects downstream.
Serum IGF-1 is the primary measured outcome of HGH therapy and the key driver of muscle growth, tissue repair, and bone density effects.
HGH directly stimulates fat breakdown in adipose tissue via its own receptors — independent of IGF-1. This is a mechanism secretagogues (sermorelin, CJC+Ipa) preserve.
Exogenous HGH suppresses the pituitary’s own pulsatile GH output. This is why GH secretagogues (which stimulate your own pituitary) have become the preferred approach for non-deficient patients.
| Benefit | Evidence |
|---|---|
| GH deficiency | Gold-standard: restores normal growth in children, normalizes body composition and metabolism in adults |
| Lean mass / fat loss | Measurable improvements; much smaller in non-deficient adults than hype suggests |
| Recovery / repair | Accelerated tissue recovery via IGF-1 |
| Sleep quality | GH pulses support slow-wave sleep |
| Bone density | Long-term improvements in BMD in deficient patients |
| Anti-aging (off-label) | Rudman 1990 study famously overstated; follow-up work shows modest effect and significant side effect burden at anti-aging doses |
For non-deficient adults seeking GH-pathway benefits, growth hormone secretagogue peptides (sermorelin, CJC+ipamorelin, tesamorelin) offer most of the upside with fewer side effects and without axis shutdown.

IGF-1 (primary), fasting glucose, HbA1c, lipids, thyroid panel. Many providers also monitor IGFBP-3. Frequency: baseline, 6–8 weeks after starting or adjusting, then every 3–6 months.
FDA-approved HGH is dispensed as pre-filled pen cartridges (Genotropin, Norditropin, Humatrope pens) or multi-dose vials with dedicated diluent. Unlike research peptides, you do not reconstitute with bacteriostatic water — the manufacturer’s diluent is the only appropriate reconstitution fluid.

HGH elevates IGF-1; any current or prior malignancy is a strict contraindication outside of licensed oncology care.
HGH / Somatropin is a prescription medication. StackTrax does not sell, prescribe, or facilitate purchase of prescription drugs.
Find a clinician who can order baseline lab work, screen for contraindications, monitor your response, and adjust dosing over time. Options to consider:
Before starting, you’ll typically want:
Avoid sources that offer prescription medications without labs, medical history, or licensed-provider oversight. If a telehealth service promises a prescription after a 5-minute questionnaire, that’s a red flag.
Build your protocol, log every dose, monitor your body's response, and get reminders so you never miss a dose.
