Overall safety summary
Sermorelin is well-tolerated. Its mild profile reflects its physiological mechanism — endogenous, pulsatile GH release remains under hypothalamic negative feedback.
Sermorelin side effects: FAQ
Is sermorelin safer than HGH?
Theoretically yes, because it preserves negative feedback and produces pulsatile rather than continuous GH. However, direct safety comparisons are limited.
