What is Sermorelin & Ipamorelin Blend?
Tap any underlined term for an instant definition.
Sermorelin & Ipamorelin Blend is a pre-formulated research preparation combining two distinct growth hormone-stimulating peptides: sermorelin (a GHRH analogue) and ipamorelin (a ghrelin-mimetic GHS). The combination produces synergistic GH release through complementary receptor mechanisms, with research showing a 3-4 fold amplification vs either peptide alone.
What It Is
- Sermorelin (GHRH 1-29): activates GHRHR on pituitary somatotrophs, driving cAMP-mediated GH release
- Ipamorelin: binds GHS-R1a on pituitary somatotrophs and suppresses hypothalamic somatostatin
- Combined in a single vial for convenience; both peptides are co-administered subcutaneously
- Ipamorelin selected for its high GH selectivity (minimal cortisol or prolactin elevation vs other GHSPs)
How It Works
- Sermorelin presses the "accelerator" via GHRHR activation
- Ipamorelin simultaneously releases the "brake" (somatostatin suppression) + adds its own direct GH-stimulating effect
- Result: GH pulse amplitude 3-4x greater than either peptide alone in matched animal studies
- IGF-1 increases 60-80% above baseline with 3-month daily administration in body composition studies
Key Research Findings
- Body composition: 12-week daily administration in research subjects showed lean mass increases of 2.5-3 kg and fat mass reduction of 2-3%
- IGF-1: Increased 60-78% from baseline at 3 months
- Sleep: Improved slow-wave sleep duration, creating positive GH feedback (better sleep = more GH)
- Selectivity: Cortisol and prolactin remain within normal range throughout treatment course
Dosing From the Literature
- Sermorelin 200-300 mcg + Ipamorelin 200-300 mcg per injection
- Once daily at bedtime (preferred) or twice daily
- Administered subcutaneous, on empty stomach
Storage and Handling
- Lyophilised: 2-8 degrees C; 24 months
- Reconstituted: 2-8 degrees C; use within 30 days
- Do not mix with other reconstituted peptides in the same syringe unless specified by protocol
