Tesamorelin is supplied here as a laboratory research compound in 3 sizes (5mg to 20mg), from $45.00 per vial, each lot documented with its identity method, purity method and test date. It is not an FDA-approved medicine. For laboratory research use only.
Identity and nomenclature
Tesamorelin is a synthetic peptide analogue of growth-hormone-releasing hormone. An approved prescription medicine containing this active ingredient exists; the material here is a laboratory research compound and not a medicine.
Tesamorelin is also listed and searched as tesamorelin peptide, tesa, tesamorelin acetate. Every one of those names refers to the same compound. A name is not an identity check, which is why the analytical record below carries more weight than the text on a label.
The research on Tesamorelin
Status: An approved medicine containing this active ingredient exists. Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone. An FDA-approved prescription medicine containing tesamorelin exists; the material listed here is a laboratory research compound supplied outside that regulated route.
Current FDA guidance and regulatory status
The existence of an approved medicine containing the same active ingredient does not make a research-grade article interchangeable with it. Approved products are manufactured under pharmaceutical quality systems, released against a compendial or filed specification, and dispensed on prescription. This is none of those things.
Status verified 2026-08-25. Regulatory positions move; check the primary source before relying on any summary, including this one.
How is Tesamorelin identity and purity established?
Identity is established with orthogonal evidence — a mass-spectrometric measurement that matches the expected molecular mass, read alongside a chromatographic purity profile. A purity percentage on its own establishes neither identity nor quantity.
Purity is reported as a chromatographic area percentage from reverse-phase HPLC, stated together with the method and the date it was run. An area percentage quoted without its method is not a result.
Two numbers are routinely confused with each other. Purity describes how much of what is in the vial is the intended compound. Net content describes how much material is actually there. A vial can be 99% pure and still contain substantially less mass than its label states, which is why the record treats them as separate measurements with separate methods.

No lot documentation is published for Tesamorelin yet. Rather than display a placeholder certificate, this record shows the gap until each field has been verified against the lot in hand.
Storage and handling
Sealed lyophilised vials are held cold and protected from light. Once a solution is prepared, stability depends on the compound, the diluent, the concentration and the temperature, so laboratories date and label prepared solutions and record the preparation in their own notes.
For solution preparation arithmetic — concentration, per-graduation values and molarity — use the Tesamorelin solution calculator or the general vial concentration tool. Those tools cover laboratory measurement only and contain no administration guidance.
Sizes and unit cost
| Size | Price | Per mg | Availability |
|---|---|---|---|
| 5mg | $45.00 | $9.00 | 9 in stock |
| 10mg | $80.00 | $8.00 | 9 in stock |
| 20mg | $150.00 | $7.50 | 9 in stock |
Volume pricing applies per size: 10–19 vials of the same size save 10%, 20 vials save 15%. Standard shipping is free over $200, and verified in-stock orders placed before 12 PM Pacific are dispatched the same day.
What an order actually costs
Say you need ten vials of Tesamorelin 10mg for a run of work. At $80.00 each that is $800.00 at list; the 10-vial tier takes 10% off, so it bills at $720.00 — $80.00 saved, and free standard shipping because the order clears $200. Twenty vials moves you to the 15% tier: $1360.00 instead of $1600.00, which works out at $6.80 per milligram against $8.00 at single-vial pricing. Volume pricing is applied per size, not across mixed sizes.
How to evaluate any supplier of Tesamorelin
This applies to us as much as to anyone else. Run these five checks before money moves.
- Verify the certificate at the laboratory, not the seller. Take the report's key or QR code to the issuing laboratory's own verification page. If it does not resolve, or resolves to a different product, the document is worthless no matter how convincing it looks.
- Check the certificate names the seller as its client. A report commissioned by somebody else tells you about somebody else's material, not about the vial in front of you.
- Match the lot on the certificate to the lot on the vial. A genuine report for a different lot is still the wrong report.
- Require a method beside every number. A purity percentage with no stated method and no test date is marketing, not a result.
- Confirm identity separately from purity. Purity describes how much of what is in the vial is the intended compound. It cannot tell you the compound is the right one — that takes mass-spectrometric evidence read alongside the chromatography.
Why regulatory status matters when you buy
Regulatory status varies by compound, formulation, intended use and jurisdiction. Listing a compound in this catalogue is not an approval, safety, efficacy, quality or suitability claim of any kind.
