Tesamorelin + Ipamorelin is a research peptide blend combining two compounds studied through distinct growth hormone signaling pathways. Tesamorelin is a GHRH analog, while Ipamorelin is a growth hormone secretagogue investigated for activity at the ghrelin receptor.
Dual-Pathway Research
Combines two research peptides studied through complementary growth hormone signaling mechanisms.
GHRH Signaling
Tesamorelin is investigated for its interaction with growth hormone-releasing hormone receptors and related endocrine pathways.
Ghrelin Receptor Research
Ipamorelin is studied for its activity at the growth hormone secretagogue receptor and associated signaling pathways.
Endocrine & Metabolic Research
Used in experimental research examining growth hormone signaling, pituitary activity, and metabolic regulatory mechanisms.
What this blend pairs
Tesamorelin and ipamorelin reach the pituitary somatotroph through two different receptors — the GHRH receptor and the growth hormone secretagogue receptor — and through two different second-messenger systems.
That is the case for studying them together. Two inputs converging on one cell is a different experimental object from a larger amount of a single input, and it is why this pairing has its own literature rather than being treated as a shortcut.
The 10mg/3mg split on the label is the split between the two components rather than two separate 10mg and 3mg products.
Handling and reconstitution
Standard lyophilised peptide handling applies. Keep the sealed vial cold and dark until it is used. Reconstitute by running bacteriostatic water slowly down the inside wall of the vial rather than firing it onto the powder cake, and let it dissolve without shaking — swirl gently if it needs help.
The concentration you end up with is set by how much water you add, not by the vial size. Our reconstitution calculator turns vial mass and water volume into a concentration and a syringe reading.
Storage
Sealed and lyophilised: refrigerated, protected from light. In solution: refrigerated, and treat time at room temperature as a cost. Avoid repeated freeze-thaw once reconstituted.
What ships, and what is on the certificate
The vial ships sealed as it was filled. Every compound in the catalogue is tested by an outside laboratory — Vanguard Laboratory in Olympia, Washington — and the certificate is published in full rather than summarised.
The certificate reports chromatographic purity by HPLC with the chromatogram visible, the measured quantity in milligrams, and an endotoxin result by LAL. Measured quantity usually reads slightly above the label, which is normal: fills are targeted high so every vial meets its stated content.
Frequently asked questions
What does 10mg/3mg mean?
It is the split between the two peptides in the blend: tesamorelin and ipamorelin in that ratio, in one vial.
Why not just use more of one peptide?
Because they act at different receptors through different second-messenger systems. Two inputs converging on one cell is not the same as more of one input.
How should it be reconstituted?
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve without shaking. The reconstitution calculator will convert vial mass and water volume into a concentration and a syringe reading.
Does it come with a certificate of analysis?
Yes. Every compound is tested by an independent laboratory and the full certificate, chromatogram included, is published on the site rather than summarised.
Is this a medicine?
No. It is sold for in-vitro laboratory research use only. It is not a drug, supplement or cosmetic, and is not for human or veterinary use.
