Where to buy Tesamorelin (also sold as Tesamorlin): the 38 vendors below are the ones we have a dated product-page price for, ranked on documentation first and price second. Nothing here is typed from memory — every number links to a date.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.
Per-milligram price is list price over labelled milligrams; it says nothing about what is in the vial. Code prices are list × (1 − the code's stated discount), not cart-tested against sales. We earn a commission on partner links; the rubric does not read partner status.
Reference size 10mg — the size most of these vendors sell. Other sizes we have on record are listed per vendor.

Tesamorelin is unusual in this category because it has an approved pharmaceutical form. It is FDA-approved as Egrifta for HIV-associated lipodystrophy, which means a well-characterised reference molecule exists. Research-grade tesamorelin is a separate product sold for in-vitro laboratory use only and is not a substitute for the prescription medicine.
That approved status makes identity testing genuinely informative — mass spectrometry can confirm a sample matches the known structure, which is not true for compounds that have never been characterised to pharmaceutical standards. It is a meaningful advantage over sourcing something like retatrutide.
Pricing on tesamorelin is tighter than on most compounds in this series. Where BPC-157 and MOTS-c show two-fold or greater spreads between vendors, tesamorelin sits within a much narrower band — so documentation quality, rather than price, should drive the decision here.
What we can verify
Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Net content: Measured net peptide published per lot (e.g. BPC-157 lot PL-BPC-05: 11.16mg vs 10mg label)
Where it falls short
Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
What we can verify
Janoshik Analytical report #223088 for BPC-157 10mg batch 10242025B2 (sample received 17 Aug, analysed 24 Aug 2026): 11.61mg measured, purity 99.635%. We opened it on the lab's own verification page (key 1GTY19EIMQE4) on 30 Sep 2026 — client, manufacturer and batch print as MyPurePeptide. A public COA directory lists 103 report records across 47 products, each with task number, verification key, report batch, the original report image and the sample photograph, plus endotoxin reports for most lots; every product page links its current report. Open catalog with sized prices (BPC-157 10mg $25; TB-500 10mg $25; GHK-Cu 100mg $35; Ipamorelin 10mg $25; Tesamorelin 10mg $40; NAD+ 500mg $35). Legal entity myPurePeptide LLC with a mailing address in Austin, Texas; Visa and American Express at checkout. Trustpilot 4.8 across 247 reviews (read 10 Oct 2026), claimed December 2025.
Net content: Report states 11.61mg measured on a 10mg label (116% — just over our 115% flag line), purity 99.635%; TB-500 #223097 11.54mg / 99.007%
Where it falls short
The printed address (12407 N Mopac Expy Ste 250 PMB 570, Austin) is a commercial mailbox, not premises — identity is awarded on the named LLC with that disclosure. The BPC-157 report measures 11.61mg on a 10mg label, 116% — just over our 115% flag line; TB-500 10mg measured 11.54mg. The vendor's own site says a report 'alone does not confirm the lot shipped'. The GLP-class pages print strike-through reference prices far above the selling price (Semaglutide 10mg 'was $399.99', now $70; Retatrutide 10mg 'was $699.99', now $80) — treat the 'you save' figures as marketing. Zelle is offered alongside cards. Returns: 7-day unopened window with a continuous unboxing video required for damage claims. A domain lookalike (mypurepeptides.com) is disclaimed on the vendor's homepage.

Where it falls short
Prices and certificates need a free account (no purchase), which since 1 November 2026 no longer costs the ungated point. All sales are final, with damage to be reported within 24 hours; checkout takes cards, but Zelle carries a 5% discount and the FAQ still lists only Zelle, Cash App, Venmo and ACH. The product pages say 'up to 12X' (ILS lots) and the cart says 'up to 16X'; both hold, because Oneday's Ethos Analytics reports carry a wider panel (checked on CJC-1295/Ipamorelin lot OC-CJI10-104, 1 November 2026). GLP-class products are sold by code (OC-2TZ, OC-3RT); the lab confirms retatrutide for OC-3RT.
Purgo Labs sits at #1 of 38 on this page: 10/10 on the rubric, 10mg at $69.99 read 1 Nov 2026. Code HEALTH gives 20% off every order. We earn a commission; it did not decide the order above.
Before you order, check the batch
A ranking tells you which vendors have good practices; it cannot tell you about the specific vial you receive. When your order arrives, compare the batch number on the label to the certificate. If they do not match, or there is no batch number, the documentation does not cover what you were sent, regardless of who you bought from. How to read a peptide COA.
As of 1 Nov 2026, 38 of the 105 vendors on our scoreboard list Tesamorelin with a price we have read on the product page: Purgo Labs, MyPurePeptide, Oneday Compounds, Panda Peptides, Premier Bio Labs, Amino Club, Snap Peptides, ezPeps, Pure Peptides, Oath Research, Pure Lab Peptides, Amplified Labs, Blue Ridge Peptides, Nexaph, Crush Research, Petratide Science, Protide Health, Loti Labs, Prime Peptides, True Peptides, ZC Labs, Peptide Partners, Kylo Peptides, Peptira, Value Research Labs, Disguised Alpha, Prime Lab Peptides, Accelerate Labs, Elite Edge Biotech, AMC Essentials, Blue Sky Peptide, Peptide Pros, Peak Lab Peptides, Ascension Peptides, Elite Peptides, Astro Peptides, Core Peptides, Atomik Labz. Every one of them is scored on the same 10-point rubric; the table above shows the score, the dated price and what you can verify before ordering.
At the 10mg size, the lowest price we have on record is Nexaph at $28.80 (read 26 Oct 2026) — Store API; sold as 'Tesamorelin 10mg (10 vials/kit)' $288.00/kit on sale, regular $368.00; per-vial = kit ÷ 10. It scores 8/10 on documentation. Price is the second sort key on this page, not the first, because an underdosed vial at a low price is the most expensive outcome.
Purgo Labs, MyPurePeptide, Oneday Compounds, Panda Peptides, Premier Bio Labs share the top score at 10/10: named laboratory, certificates that resolve on the laboratory's own site, measured milligrams against the label, and a published legal identity. The per-criterion evidence, with dates, is on each vendor's review page.
Tesamorelin is sold by these vendors as a research chemical for laboratory use, not for human consumption; none of it is FDA-approved in this form. Legality of purchase varies by jurisdiction and the compound, and it is your responsibility to know your local rules. Our pages assess documentation and pricing; they are not legal or medical advice.
Rubric score first. Among equal scores, our editorial pick (Purgo Labs) comes first, then a short, named list of affiliate partners we choose to list first inside a tie, then the lower verified price per milligram at 10mg, then the larger independent review base. 14 of the 38 vendors here are partners. A partnership never changes a score and never moves a vendor above one with a higher score.
No. Egrifta is an FDA-approved prescription medicine for HIV-associated lipodystrophy, manufactured under pharmaceutical controls and dispensed by licensed pharmacies. Research-grade tesamorelin is sold for in-vitro laboratory use only, is not FDA-approved, and is not a substitute for a prescribed medicine.
In one specific way, yes. Because an approved pharmaceutical form exists, tesamorelin is a well-characterised molecule — so mass spectrometry identity testing can confirm a sample matches the known structure. For compounds that have never been characterised to pharmaceutical standards, such as retatrutide, there is no equivalent benchmark. It does not make any particular vendor more trustworthy, but it does make their COAs more interpretable.
Several vendors sell tesamorelin combined with CJC-1295 and ipamorelin. Blends cost less per milligram and are convenient, but they make it impossible to attribute an observed effect to tesamorelin specifically. For controlled work the single compound is cleaner; for general GH-axis work the blends are a reasonable economy.
