BlendGrowth Hormone

Sermorelin + Ipamorelin 10mg

A 1:1 dual-pathway secretagogue blend formulated to examine synergistic somatotroph stimulation and pulsatile growth hormone secretion.

SermorelinIpamorelin

Mechanism

The blend concurrently activates pituitary GHRH receptors via sermorelin and GHS-R1a receptors via ipamorelin, driving amplified pulsatile growth hormone release through complementary secondary messenger pathways.

Dosing

Published research protocols commonly initiate titration at 300 mcg of total blend administered once daily on a 5-day on, 2-day off cycle.

Reconstitution

Reconstitution of the 10 mg composite vial with 3.0 mL of bacteriostatic water yields an overall blend concentration of 3,333 mcg/mL (approximately 1,667 mcg/mL per constituent).

Storage

Store the unmixed lyophilized powder at -20 °C, and maintain the reconstituted liquid between 2 °C and 8 °C protected from light without freezing.

Reconstitution Steps

  1. 1

    Draw exactly 3.0 mL of bacteriostatic water using a sterile syringe.

  2. 2

    Introduce the diluent slowly against the inside glass wall of the vial to minimize agitation.

  3. 3

    Swirl the vial gently until the lyophilized cake fully dissolves, avoiding vigorous shaking.

  4. 4

    Affix a label indicating the reconstitution date, the 3,333 mcg/mL total concentration, and the 1:1 constituent ratio.

  5. 5

    Refrigerate the dissolved blend at 2–8 °C, shielded from light exposure.

Overview

The Sermorelin and Ipamorelin composite combines an active growth hormone-releasing hormone fragment with a selective ghrelin receptor agonist within a unified 10 mg lyophilized formulation. By targeting distinct receptors on the anterior pituitary, the combination is frequently investigated for its potential to trigger complementary intracellular cascades, thereby accentuating endogenous growth hormone pulses without disrupting baseline physiological rhythmicity. Sermorelin corresponds to the truncated 29-amino-acid bioactive terminal of endogenous GHRH, primarily responsible for setting pulse amplitude. In contrast, ipamorelin functions via the secretagogue receptor GHS-R1a to induce hormone discharge without significantly provoking secondary adrenocorticotropic or prolactin pathways. Integrating both entities at an equal mass ratio enables researchers to explore multivalent secretagogue dynamics from a single combined experimental preparation. Because this blend provides both agents in an unalterable 1:1 proportion, investigation is restricted to fixed-ratio paradigms. The protocol outlines standard laboratory preparation guidelines, measurement equivalents on U-100 syringes, and volumetric titration frameworks suited for in vitro and comparative physiological models.
