Ipamorelin + Tesamorelin 10mg Blend (5mg + 5mg)
A dual-action 1:1 secretagogue blend combining GHRH analog tesamorelin and selective ghrelin agonist ipamorelin for GH-axis study.
Mechanism
Stimulates the pituitary somatotropic axis via complementary dual-receptor pathways by binding both GHRH receptors (tesamorelin) and ghrelin GHS-R1a receptors (ipamorelin) to induce pulsatile growth hormone secretion.
Dosing
Standard laboratory protocols document an initial daily administration of 330 mcg total blend (10 units on a U-100 syringe) administered subcutaneously.
Reconstitution
Reconstituting a 10 mg blend vial with 3.0 mL of bacteriostatic water yields an approximate working concentration of 3.33 mg/mL (or roughly 1.67 mg/mL of each active peptide).
Storage
Store the unmixed lyophilized vial at -20 °C protected from moisture, and once reconstituted, keep refrigerated at 2–8 °C away from light without freezing.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–4 | 330 mcg total (1× daily) | 10 units (0.10 mL) |
| Weeks 5–8 | 500 mcg total (1× daily) | 15 units (0.15 mL) |
Reconstitution Steps
- 1
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
- 2
Slowly introduce the diluent against the internal glass wall of the blend vial to minimize turbulence and foaming.
- 3
Gently roll or swirl the container until all lyophilized powder is visibly dissolved without vigorous shaking.
- 4
Record the date and resulting concentration on the vial label and place into refrigerated storage at 2–8 °C.

Overview
The Ipamorelin + Tesamorelin blend combines two distinct growth hormone secretagogues into a single 1:1 ratio research vial. By co-formulating a stabilized growth hormone-releasing hormone (GHRH) derivative with a selective growth hormone secretagogue receptor (GHS-R1a) agonist, this blend allows laboratory investigators to evaluate dual-pathway activation of the somatotropic axis simultaneously without preparing multiple injections. Tesamorelin drives endogenous growth hormone release by activating pituitary GHRH receptors, while ipamorelin functions downstream via the ghrelin receptor to amplify pulsatile secretion with minimal influence on prolactin or cortisol levels. Research models frequently assess whether the combined activation yields complementary or synergistic increases in circulating IGF-1 concentrations, lipolysis, and lean tissue preservation compared to single-agent administration.
