Where to buy Semaglutide (also sold as GLP-1 S, GLP-1 SM): the 21 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.

Semaglutide is the most-searched compound in this category and, partly because of that, the one where sourcing standards vary most. It has been FDA-approved as Ozempic for type 2 diabetes since 2017 and as Wegovy for chronic weight management since 2021 — but those are prescription medicines. Research-grade semaglutide is a separate product sold for in-vitro laboratory use only.
The FDA has issued explicit public warnings about unapproved and compounded versions of GLP-1 drugs including semaglutide, noting that they do not undergo review for safety, effectiveness or quality before being marketed. It has also issued warning letters to online vendors selling it. That regulatory attention is the single most important context for anyone evaluating a research supplier here.
Since the 2025–26 enforcement wave almost no vendor lists semaglutide by name: it is sold as GLP-1 S, GLP-1 SM, VRC-1S, PS-S1 and a dozen other house codes. The decoder table below shows what each vendor calls it and how we established the identity — a CAS number on the listing, the lab lot prefix on the vendor's own certificate page, or the vendor's FAQ. A code with none of those is a code only, and we keep it out of the price table.
Because demand is so high, availability is not a differentiator — nearly every vendor stocks it. What separates them is whether they will tell you which laboratory tested the batch, and whether the certificate matches the vial you receive.
Almost no vendor lists Semaglutide by name any more. The table shows the code each one sells it under and how we established that the code means Semaglutide — a CAS number on the listing, the lab lot prefix on the vendor's own certificate page, or the vendor's own FAQ. A code with no stated identity is listed as exactly that: the vendor is asking to be taken on trust, and we do not put those in the price table above.

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.

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.
What we can verify

Net content: Vanguard Laboratory PDF for lot PG-5101 (TB-500 5mg) reports 4.92mg measured vs 5mg, 99.30% purity — read 6 Sep 2026
Where it falls short
Small review base (65 on Trustpilot, 26 Sep 2026). Measured net content could not be read from the certificate images. The legal entity name appears on the refund policy but not the About page. GLP products sold under house codes PG-1SG / PG-2TZ / PG-3RT.
Purgo Labs sits at #1 of 21 on this page: 10/10 on the rubric, 10mg at $49.99 read 1 Nov 2026 (also 20mg $109.99). 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, 21 of the 105 vendors on our scoreboard list Semaglutide with a price we have read on the product page: Purgo Labs, MyPurePeptide, Peptide Giants, Panda Peptides, Amino Club, ezPeps, Oath Research, PS Peptides, PeakForce Labs, Loti Labs, Prime Peptides, Peptide Partners, Value Research Labs, Disguised Alpha, Prime Lab Peptides, Profound Aminos, Optima Supply, Blue Sky Peptide, Peak Lab Peptides, Valor Peptides, Polaris Peptides. 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 Value Research Labs at $27.99 (read 31 Oct 2026) — sale; list $39.99 struck; sold as 'VRL-1 (SM)'; BOGO + 30% sitewide; read from the store API, https://valueresearchlabs.com/product/vrl-1-sm/. It scores 7/10 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, Peptide Giants, Panda Peptides 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.
Semaglutide 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. 8 of the 21 vendors here are partners. A partnership never changes a score and never moves a vendor above one with a higher score.
No. This page compares research-material vendors, which sell lyophilized semaglutide for laboratory use only. Prescription semaglutide (Ozempic, Wegovy injection, the Wegovy pill approved in December 2025, and Wegovy HD 7.2 mg approved in March 2026) is prescribed by a licensed clinician and dispensed by a pharmacy. Our semaglutide FDA approval page lists every approved product and date.
No. Ozempic and Wegovy are FDA-approved prescription medicines made under pharmaceutical manufacturing controls and dispensed by licensed pharmacies. Research-grade semaglutide is sold for in-vitro laboratory use only, is not FDA-approved, and is not a substitute for a prescribed medicine. The FDA has publicly warned that unapproved versions do not undergo review for safety, effectiveness or quality.
Yes. The FDA has issued public warnings about unapproved and compounded GLP-1 drugs including semaglutide, and has sent warning letters to online vendors selling it. Enforcement escalated through 2025 and 2026 from warning letters to raids and prosecutions, and at least nine notable vendors closed in that window. Vendor longevity is a genuine consideration here.
Because demand is enormous and the barrier to listing a product is low, availability tells you nothing. Almost every vendor stocks semaglutide. The meaningful questions are whether the vendor names the laboratory that tested the batch, whether the COA carries a batch number matching your vial, and whether identity testing by mass spectrometry was performed — not just a purity percentage.
Not necessarily, but for semaglutide specifically the price spread across vendors is wide enough that a very low price is worth interrogating. The compound is expensive to synthesise correctly. Rather than treating price as a quality proxy in either direction, filter first on documentation — named lab, batch-matched COA, identity testing — and compare price only among vendors that clear that bar.
