Safety summary
Contraindications
- Active cancer or recent cancer history — IGF-1 elevation is the mechanism to avoid
- Pregnancy or breastfeeding
- Severe primary pituitary failure — Sermorelin works by stimulating the pituitary, so a pituitary that cannot respond is not the right target
- Patients on supraphysiologic glucocorticoids — the steroid signal blunts the GH axis Sermorelin is trying to wake up
Side effects
- mildBrief facial flushing post-injection.
- mildInjection-site soreness or a small bump for 24 hours.
- mildMild headache in the first week for some users — usually fades.
Sermorelin
The oldest GHRH analogue still in widespread use — the first 29 amino acids of natural GHRH, unmodified. Pulses the pituitary in line with the body's natural sleep-onset GH window.
