Growth Hormone
CJC-1295
Rather than taking growth hormone directly, this tries to boost your own supply. People turn to it for recovery, sleep and body shape as natural hormone levels fall with age. Almost always paired with Ipamorelin, and mostly found through private UK clinics rather than the NHS.
GH-releasing , almost always paired with Ipamorelin — used for recovery, sleep and body composition.
How well studied
Tier Guide: A = Well studied, B = Some good studies, C = Early evidence & D = Barely studied
Tested in people, but in smaller or fewer studies. A decent picture, just less certain.
How it works
Your pituitary gland — a small hormone-control centre in the brain — gets nudged into releasing longer, stronger bursts of growth hormone.
Extends the natural pulse of growth release from the pituitary, raising GH/ over time.
Reported benefits
- Raises GH/IGF-1 pulses supporting recovery and sleep quality
- Supports lean mass retention alongside training

Dosage
No established self-administration dose — limited controlled human trials for this specific use. UK private clinics prescribe under individualised titration.
Side effects
- Injection site reactionsreported
- Water retentionreported
- Elevated IGF-1 — theoretical hormone-sensitive tissue concernmonitoring-relevant, unresolved
Getting it in the UK
Still legal for a doctor to prescribe, but it hasn't been officially approved for this specific use. Uncommon, and comes down to a specialist's own judgement.
MHRA: the UK government body that checks a medicine is safe and actually works before doctors are allowed to prescribe it.
