Sermorelin — Wolverine Health

How it works

The most clinically tested GH-stimulating peptide in this class. It's a synthetic fragment of natural GHRH — the signal your hypothalamus sends to trigger pituitary GH release. Once marketed as Geref for GH deficiency diagnostics in children. The clinical development history is real; so are the limitations: it works on a declining pituitary, so age and baseline function determine the ceiling.

FDA status: Previously marketed as Geref (withdrawn from commercial market). No current approved indication. Compoundable by 503A pharmacies as it is not an FDA-approved drug with an active NDA.
WADA status: Permitted in sport
Route: subcutaneous injection

Key studies

Sermorelin: a better approach to management of adult-onset GH insufficiency — Walker et al.

Sermorelin (GHRH 1-29) stimulates GH secretion via pituitary GHRH receptors and has been studied as a diagnostic and therapeutic agent for growth hormone insufficiency in adults.

Research on Sermorelin

Growth hormone secretagogues: what they are and why four peptides keep showing up together

WADA

CJC-1295, ipamorelin, sermorelin, and tesamorelin all sit in the growth-hormone-secretagogue class. They are routinely confused for each other. Here is the mechanism, the human evidence on each, and the four separate regulatory files behind the shared label.

Sermorelin vs tesamorelin: two routes to the same receptor, two very different approval histories

WADA

Sermorelin and tesamorelin hit the same pituitary receptor and pull the same upstream lever on growth hormone. One had two FDA approvals and lost them for business reasons. The other still has one, for a population almost no buyer belongs to. Same mechanism, different paperwork.

Sermorelin: the older growth hormone peptide that still has defenders

WADA

Sermorelin had a real FDA approval, lost it for business reasons, and lives on as the anti-aging clinic's GH peptide of choice. Here's what the human evidence actually shows, what gets quietly substituted in its name, and where the longevity case is honest.
