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.
