Real listing aggregated from the vendor's public page. Buying happens on their site, never on VialGrade — outbound links stay off until the affiliate step is approved.
Independently tested — with one caveat
- An independent lab record backs Sports Technology Labs' Tesamorelin at 100.0% — the exact evidence most listings lack.
- A certificate covers one submitted batch, not every vial — confirm it matches the batch you receive.
How to verify this yourself
Check the seller's COA is for YOUR batch number, then paste it into Verify to confirm it's a real, unedited Janoshik record.

Cheapest Tesamorelin, by price per mg
Vials come in different sizes, so the sticker price lies. This ranks every listing by what a milligram actually costs — with independent test purity where we have it.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg.
Understand this compound
What is Tesamorelin?
FDA-approved moleculea.k.a. Egrifta, Egrifta SV, Egrifta WRA GHRH analog known from prescription use for visceral-fat research contexts.
Good to know: Approval is specific to HIV-associated lipodystrophy; use outside that population (e.g., general fat loss) is off-label and unstudied for efficacy and safety in that context.
How does Tesamorelin work?
A modified 44-amino-acid GHRH analog; stimulates the pituitary to release endogenous growth hormone, raising IGF-1.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Tesamorelin researched for?
Studied specifically for reducing excess visceral abdominal fat in HIV-associated lipodystrophy, and more broadly researched for GH-axis and fat-metabolism questions.
- Growth hormone supportStudied for how it interacts with the body's own growth-hormone axis in research settings.
- Weight & metabolicStudied in weight, appetite, blood-sugar, and fat-metabolism research.
How far has the research gone?
FDA-approved (for HIV-associated lipodystrophy); approved as Egrifta/Egrifta SV/Egrifta WR for reduction of excess visceral fat in adults with HIV and lipodystrophy.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What is Tesamorelin commonly stacked with?
Compounds the research community frequently discusses alongside Tesamorelin. Not a protocol or a recommendation — a map of what to read about next.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row answers a different question. Passing the identity test doesn’t mean it’s sterile or correctly dosed — we show each answer separately.
Identity — independent test
EstablishedAn independent lab record backs this vendor's testing for this compound.
Measured purity (HPLC)
EstablishedIndependently measured 99.95%. Read from the certificate, not re-measured by VialGrade.
Batch traceability
UnknownNo specific batch on this listing has been matched to an independent record.
Sterility & endotoxin
Not testedA purity COA does not measure sterility or endotoxins — no such test is on record.
Dose / fill accuracy
UnknownVialGrade does not independently measure vial fill or delivered dose.
These certificates are for Tesamorelin across every maker VialGrade tracks — not necessarily Sports Technology Labs’s own stock. This listing’s specific evidence is the matrix above.
Independent testing
Independent lab tests on record for Tesamorelin
Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.
How does this data get here?
Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.
Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.
We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.
What a certificate does & doesn’t prove
Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.
Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.

Testing claim is backed by an independent record
An independent record for Sports Technology Labs's Tesamorelin exists in the lab's own feed, measured at 99.95%. The advertised testing is backed by evidence the vendor can't edit — though not necessarily the exact batch you'll receive.
- Independent confirmation. A third-party record references Sports Technology Labs for Tesamorelin.
- Measured purity. Independently measured at 99.95%.
Certificate analyzed 2026-06-10
Open the independent certificateCross-checks the vendor’s testing claim against independent lab records. Purity is read from the lab's certificate as issued — VialGrade doesn't re-run the assay or sample the vial. It reflects one lab's result for one submitted batch, not every vial. Never a statement that a product is safe, sterile, or correctly dosed.
This is a prescription drug in the US
This is an approved drug (Egrifta) — an FDA-approved prescription medication. Buying a “research” version sidesteps the prescription requirement and the approved, quality-controlled supply chain. The FDA has warned about and acted against unapproved and compounded copies. Higher legal and safety exposure than an unapproved research peptide.
