Sermorelin 10 mg
GHRH(1-29) analogue — the minimum fragment with full GH-releasing activity.
Sermorelin is the 29-amino-acid N-terminal fragment of GHRH — the minimum sequence for full GH-releasing activity.
What the peptide is.
Sermorelin (GRF 1-29) represents the minimum active fragment of GHRH. It has a short plasma half-life (~12 minutes) and was historically approved as a diagnostic agent for GH-deficiency evaluation.
The commercial product (Geref) was discontinued in 2008 — not for safety reasons. Widely used in preclinical GH-axis research today.
Classical GHRH-receptor agonism; short-acting pulsatile stimulus to pituitary GH release.

- Q.Why was Geref discontinued?
- A.The withdrawal was commercial, not safety-related. More targeted GHRH analogues (tesamorelin) and alternative diagnostic approaches displaced the commercial indication.
