Tesamorelin

Growth-hormone secretagogue Strong evidence 3 cited studies 84 live vendors

Tesamorelin is a synthetic analog of growth-hormone-releasing hormone (GHRH), a 44-amino-acid peptide modified for greater stability against enzymatic degradation, and is classified as a growth-hormone secretagogue. In laboratory and preclinical contexts it is studied for its interaction with GHRH receptors and downstream signaling of the somatotropic axis. This index tracks research-use-only (RUO) vendor pricing for Tesamorelin to help researchers compare cost across suppliers.

Evidence brief

Tesamorelin is a growth-hormone-releasing hormone (GHRH) analogue studied in multiple randomized controlled trials and pooled in a meta-analysis, almost entirely in people with HIV-associated abdominal fat accumulation.

Computed from 117 in-stock listings across 84 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

▸ Why compare $/mg for Tesamorelin?

Per-mg prices for Tesamorelin vary because vendors differ in synthesis scale, purity grade, lyophilization and fill quantity per vial, and how they amortize third-party testing across a batch. Comparing normalized $/mg across suppliers lets a researcher gauge whether a listing reflects genuine value or simply a smaller vial size or thinner documentation.

▸ Reading the COA

For Tesamorelin, confirm identity by mass spectrometry against the expected monoisotopic/average mass of the modified 44-residue GHRH sequence, and check that reported HPLC purity meets or exceeds a stated threshold (commonly 98%+ for research peptides). Because it is a long-chain peptide, watch for truncated or deletion sequences and residual synthesis byproducts (TFA counter-ion, acetate) noted on the COA; a lot-specific COA tied to the vial's batch number, not a generic template, is the meaningful signal for verifying the material.

▸ FAQ

How is lyophilized Tesamorelin typically stored in a research setting?
As a lyophilized (freeze-dried) peptide, Tesamorelin is generally stored sealed, protected from light and moisture, at low temperature (commonly -20°C or colder) for long-term storage per the vendor's stated conditions. As a longer-chain peptide, it can be susceptible to degradation from repeated temperature cycling and moisture exposure, which is why the vendor's specification sheet lists the storage conditions intended to preserve the identity and purity of the material. Refer to that vendor specification sheet for the stated stability conditions for a given lot.
What is a COA and what should I check on one for Tesamorelin?
A Certificate of Analysis (COA) is a lab document that reports the analytical testing performed on a specific production lot. For Tesamorelin, the key items are mass-spec confirmation of identity against the expected peptide mass, an HPLC chromatogram with a stated purity percentage, and the batch/lot number matching your vial. It verifies the identity and purity of the material itself and makes no claim about any biological outcome.
Why do per-mg prices for Tesamorelin differ so much between vendors?
Differences come from synthesis batch size, the stated purity grade, the amount of peptide per vial, and whether the vendor includes lot-specific third-party analytical testing. A low headline price may reflect a smaller fill quantity or less documentation, which is why comparing normalized cost per milligram alongside the available COA gives a clearer picture than sticker price alone.
