Tesamorelin 12mg + Ipamorelin 6mg — 18mg
Research-grade Tesamorelin + Ipamorelin blend, a pre-combined 2:1 formulation of Tesamorelin (12mg) and Ipamorelin (6mg) studied for dual-pathway growth-hormone signalling. 18mg total lyophilized powder, 99%+ purity verified by Janoshik Analytical via HPLC and mass spectrometry.

The Tesamorelin + Ipamorelin blend combines two compounds that act on different receptors — which is the entire reason researchers pair them. Tesamorelin is a stabilised GHRH analog engaging the GHRH receptor; Ipamorelin is a selective growth-hormone secretagogue engaging the ghrelin receptor (GHS-R). Combining a GHRH-class and a GHS-R-class compound in one vial lets researchers examine dual-pathway signalling without sourcing and reconstituting two separate vials.
Durham Peptides supplies the blend at a 2:1 ratio — 12mg Tesamorelin to 6mg Ipamorelin, 18mg total. For researchers who need independent control over the ratio, the individual compounds are also stocked: Tesamorelin 10mg and 20mg, and Ipamorelin 10mg.
BENEFITS
Dual-pathway design — GHRH-receptor and GHS-R engagement in a single formulation
Convenience — eliminates the need to source and reconstitute two separate vials
Fixed 2:1 ratio — consistent, reproducible co-administration across runs
Complementary mechanisms — the two classes are studied for additive rather than overlapping effects
Verified identity — both components MS-confirmed against a Janoshik report

WHAT IS THE TESAMORELIN + IPAMORELIN BLEND?
It is a research blend combining Tesamorelin (12mg) and Ipamorelin (6mg) in a single vial at a 2:1 ratio, 18mg total. The two compounds engage different receptors — GHRH and GHS-R respectively — so the blend lets researchers study dual-pathway growth-hormone signalling from one reconstitution.
WHY COMBINE TESAMORELIN AND IPAMORELIN?
Because they act on separate receptors. Tesamorelin is a GHRH analog engaging the GHRH receptor; Ipamorelin is a selective secretagogue engaging the ghrelin receptor. Researchers study the pairing to examine whether the two pathways produce additive or synergistic signalling that neither compound generates alone.
BLEND VS BUYING TESAMORELIN AND IPAMORELIN SEPARATELY?
The blend fixes the ratio at 2:1 and requires a single reconstitution, which suits reproducible repeat runs. Buying Tesamorelin 10mg or 20mg and Ipamorelin 10mg separately gives more material per compound and full control over ratios. Durham Peptides stocks both routes; the choice depends on whether the work calls for fixed co-administration or independent dosing.
WHY A 2:1 RATIO?
The 12:6 split reflects the typical relative quantities used when the two classes are studied together, with the GHRH-class compound as the larger fraction. Researchers needing a different ratio should use the individual vials.
HOW SHOULD THE BLEND BE STORED AND RECONSTITUTED?
Store the lyophilized vial at 2–8°C, protected from light and moisture. Reconstitute with bacteriostatic water (sold separately). Once reconstituted, keep refrigerated and use within an appropriate research timeframe.
IS THE COA VERIFIABLE?
Yes. Every batch is Janoshik-tested with a unique report key you can confirm independently — see our guide on how to verify a Janoshik unique key.
