The definitive reference for sermorelin research — covering GHRH mechanism, dosage protocols, head-to-head comparisons with HGH and ipamorelin, side effects, legal status, and sourcing.
Mechanism & Research
Full mechanism overview: GHRH receptor agonism, pulsatile GH release, IGF-1 upregulation, and clinical applications. Sermorelin preserves the hypothalamic-pituitary feedback axis — unlike exogenous HGH.
Dosage & Protocols
Standard dosing protocol: 200–500 mcg subcutaneous injection before sleep, leveraging the natural nocturnal GH pulse. Cycle length typically 3–6 months for research applications.
Side Effects & Safety
Injection site reactions, flushing, water retention, and rare adverse events. Evidence-graded safety profile with comparison to exogenous HGH — sermorelin's axis-preserving mechanism produces a more favorable safety profile.
