Human Growth Hormone (HGH)
Human Growth Hormone is a peptide hormone produced by the pituitary gland that governs growth, metabolism, body composition, and cellular repair. Synthetic HGH (somatropin) is used for anti-aging, fat loss, muscle preservation, and recovery. Unlike anabolic steroids, HGH produces gradual, quality changes over months and doesn't suppress natural testosterone.
- Also known as: HGH, Somatropin, GH
- Form: injectable
- Half-life: ~15–20 minutes (active), effects last 24+ hours

- Typical dose (women): 1–2 IU/day
- PCT required: no
Dosing by experience level
| Level | Dose | Frequency | Notes |
|---|---|---|---|
| Anti-Aging / TRT | 1–2 IU/day | Daily, fasted morning or before bed | Minimum 3-6 months for benefits |
| Performance | 3–4 IU/day | Split AM/PM | Stack with insulin and IGF-1 for advanced protocols |
| Advanced | 6–10 IU/day | Split doses | High dose — significant insulin resistance risk |
Side effects
- Insulin resistance / elevated blood sugar
- Carpal tunnel syndrome
- Joint pain (water retention in joints)
- Acromegaly at very high doses
- Lethargy initially
- Elevated IGF-1 (cancer risk theoretical)
Common stacks
- Testosterone Enanthate
- Insulin

Important notes
- Does not suppress natural testosterone — no PCT needed
- Results are slow (3-6 months) but long-lasting
- Best protocol: inject before sleep or fasted morning
- Peptide secretagogues (CJC-1295 + Ipamorelin) are safer, cheaper alternatives
- Pharmaceutical grade somatropin required for research — avoid generic Chinese brands
