Tap a column heading to sort. Lab-hosted = the certificate resolves on the laboratory's own system, not only on the vendor's site. Entity = a registered company name and street address on the vendor's own pages. Prices are list prices on the date read; codes are confirmed from partner terms.
Which company for which need
How this list is chosen
The rule is the whole method: a vendor is on this page if, and only if, it is still trading and scores 9 or 10 of 10 on our verification rubric. We do not add a vendor because it is popular, remove one because it is small, or move one because it pays us. When the bands change, the list changes with the next build, and the title prints the current count.
The ten criteria, with the share of all 80 scored vendors that currently pass each:
- Names its testing laboratory · 81% pass
- Certificates verifiable at the lab, not just the vendor · 60% pass
- Batch-specific COAs matched to lots · 80% pass
- Publishes measured net content vs label · 73% pass
- COAs and pricing viewable without an account · 71% pass
- Independent review base (50+ on an external platform) · 43% pass
- No contradictions among its own claims · 29% pass
- Vial sizes stated with prices · 85% pass
- Publishes a legal entity and street address · 43% pass
- No misleading trust signals or buyer-protection workarounds · 70% pass
Vendors are grouped by score, and vendors on the same score are tied — they share a place (T-1, T-5). Inside a tied band the order carries no evidential weight: our own pick is shown first and labelled as ours, then a short, disclosed list of vendors we choose to list first (all affiliate partners — named in the FAQ), then the rest by name. A partnership never changes a score and never moves a vendor across a band.
What a score is not: it is not a test of any vial you receive, and it is not a safety claim. It says the vendor's documentation can be checked by a stranger, which is the only thing a review site can verify from outside. For the eight buyer questions on each company, open its "Is it legit?" page.

Vendors between 5 and 8 are on the scoreboard with the criteria they miss; several are one checkable certificate away from this list.
Best peptide companies: questions readers ask
What is the best peptide company in 2026?
On our 10-point verification rubric 4 vendors clear every check: Purgo Labs, MyPurePeptide, Peptide Giants, Idun Peptides. They are tied on the evidence, so we print them as T-1 rather than pick a winner the rubric cannot justify. Our own pick inside that tie is Purgo Labs, labelled as ours, because it is the reference the rubric was built against.
How did you choose the best peptide vendors?
By rule, not by taste: every vendor still trading with a rubric score of 9 or 10 out of 10 is on the list, in scoreboard order, and nobody else is. The ten criteria are a named lab, certificates checkable on the lab's own system, per-lot COAs, measured net content, ungated COAs and prices, an independent review base of 50 or more, no self-contradiction, vial sizes next to prices, a published legal entity and address, and a clean record on trust signals and payment rails. 80 vendors are scored; 10 qualify.
Are the best peptide companies on this list affiliate partners?
8 of the 10 are: Purgo Labs, MyPurePeptide, Peptide Giants, Rivn Peptides, Ameano Peptides, Amino Club, TrustedPeps, Modified Aminos. Idun Peptides, Pure Peptides are not, and sit on the list because the evidence put them there. A partnership never changes a score and never moves a vendor across a band; inside a tie, the vendors we list first are disclosed as partners on the scoreboard.
Which peptide company is cheapest for BPC-157?
Among the 10 listed, MyPurePeptide has the lowest per-milligram BPC-157 price we recorded: $25 for 10mg, read 10 October 2026. Prices move; the price index shows the history across every vendor.
Which of the best peptide vendors sell semaglutide, tirzepatide or retatrutide?
Purgo Labs, MyPurePeptide, Peptide Giants, Idun Peptides, Rivn Peptides, Amino Club list at least one of the three, some under a product code rather than the compound name. The best-vendors pages for semaglutide, tirzepatide and retatrutide carry the code-to-lot mapping and the dated prices.
Are these peptide companies legit?
Each has its own "Is it legit?" page answering eight buyer questions: real company, lab checkable outside the vendor, independent reviews, money-back terms, enforcement history, lookalike domains, self-contradiction, and whether you can inspect before paying. A high rubric score means the documentation checks out; it is not a claim about what is in any vial you receive, and nothing here is medical advice. These are research chemicals sold for laboratory use.
How often is this list updated?
The list recomputes from the data layer every time the site is built. Prices are re-read weekly, Trustpilot monthly, and every score change is dated on the scoreboard's changelog and on the vendor's own page. The newest read on this page is 10 October 2026.
What do people on Reddit say the best peptide companies are?
Reddit threads on the question are anecdotal, some are vendor-seeded, and the names recommended in older threads include vendors that have since closed (the closures hub lists them with sources). We read the threads for each vendor and label what we found on its review page, but none of it is a scoring input; the rubric is.
