Sermorelin 10mg
A truncated synthetic GHRH analog studied for its ability to stimulate endogenous pituitary growth hormone secretion in nightly research protocols.
Mechanism
Binds selectively to pituitary GHRH receptors to trigger episodic, endogenous growth hormone secretion while preserving physiological somatostatin feedback control.
Dosing
Documented laboratory protocols initiate evaluation with an introductory nightly dose of 100 mcg administered subcutaneously prior to rest.
Reconstitution
Reconstituting a 10 mg vial with 3.0 mL of bacteriostatic water yields an approximate working concentration of 3.33 mg/mL (3,333 mcg/mL).
Storage
Store the unmixed lyophilized vial refrigerated between 2 and 8 °C protected from light, and keep the reconstituted solution refrigerated at 2 to 8 °C without freezing, utilizing it within 10 to 14 days.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–2 | 200 mcg (1× nightly) | ~6 units (0.06 mL) |
| Weeks 3–4 | 300 mcg (1× nightly) | ~9 units (0.09 mL) |
| Weeks 5–6 | 400 mcg (1× nightly) | ~12 units (0.12 mL) |
| Weeks 7–8 | 500 mcg (1× nightly) | ~15 units (0.15 mL) |
Reconstitution Steps
- 1
Aspirate exactly 3.0 mL of sterile bacteriostatic water using a fresh syringe.
- 2
Introduce the diluent gently along the interior glass wall of the 10 mg vial to avoid peptide shearing and excess foam.
- 3
Swirl the vial with slow, circular motions until the lyophilized cake is fully dissolved without vigorous agitation.
- 4
Affix a label noting the reconstitution date and resulting 3.33 mg/mL concentration, then place immediately into refrigerated storage at 2–8 °C away from light.

Overview
Sermorelin is a synthetic peptide representing the first 29 amino acids of human growth hormone-releasing hormone, corresponding to the functional region responsible for pituitary stimulation. By interacting directly with somatotropes in the anterior pituitary gland, it prompts the natural release of endogenous somatotropin while maintaining normal endocrine feedback mechanisms. In laboratory and experimental models, sermorelin serves as a non-exogenous route to assess somatotropic function without completely suppressing native feedback loops. Unlike recombinant somatropin, its action depends heavily upon an intact, functioning pituitary axis and respects normal physiological inhibitory signals, notably somatostatin regulation.
