Row 1, Peptara Labs: eight cells and the page behind each one
Peptara Labs is row 1 of our index. Here's each cell next to its source page and the date we read it.
Links to Peptara Labs are affiliate links, and we may earn a commission when you buy through them.
Does Peptara Labs sell through pharmacies or shops?
No, by its own account. Its where-to-buy page (read 2026-09-01) says it plainly: no retail channel and no pharmacy shelf. The catalogue is on its own site.

Source: the certificate index.
Which files did we open?
Five, on 2026-09-01, all linked from the certificate index. Three are certificates, each a four-page PDF. Two are second-laboratory reports, each a PNG image of 1600 by 2360 pixels. They're linked below as files 1 to 5.
Compounds behind these files: research-grade material with no approved human use. Other files on the index are published and linked; we didn't open them.
Which lots and certificates are listed?
| Item | Lot | Certificate | HPLC purity, as published | Tested |
|---|---|---|---|---|
| GHK-Cu | GHKCU-260417-A | COA-2026-4173 | 99.62% | June 2026 |
| Retatrutide | RETA-260512-A | COA-2026-6928 | 99.18% | June 2026 |
| Semax | SMX-260407-A | COA-2026-6071 | 99.05% | June 2026 |
| BPC-157 | BPC-260408-A | COA-2026-8642 | 99.04% | June 2026 |
| TB-500 | TB5-260415-A | COA-2026-2087 | 98.86% | June 2026 |
Sources: the homepage lot list, read 2026-09-07, and the certificate walkthrough, read 2026-09-01, which names COA-2026-8642 as the certificate for lot BPC-260408-A.
Which laboratory tests it?
The certificates name Titreon Analytical, and we only print that name with the words Peptara Labs uses for it: described by Peptara Labs as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited.
The name and alignment come from the certificate index, the qualifier from the trust page (all read 2026-09-01). Those last three words matter most, because a shortened version would drop them.
Sources: the certificate index, and the trust page.
How long has Peptara Labs been around?
Not long, it seems: "newer platform" is its own term, on its trust page (read 2026-09-01). We hold no founding date. The same page names the entity: Peptara Labs LLC, registered in Wyoming.
Is there a second laboratory?
Yes. Peptara Labs publishes 4 second-laboratory endotoxin reports on its certificate index (read 2026-09-01) and says each key can be checked at janoshik.com/verify. We haven't checked one, and we print the address unlinked. Files 4 and 5 above are two of those reports.
What else does each certificate test?
Four more lines beyond identity and purity: sterility, bacterial endotoxin, a fentanyl immunoassay screen and five metals (lead, arsenic, mercury, chromium and cadmium), all Not Detected on the published batches.
Identity is by HPLC retention-time matching and LC-MS. Purity by HPLC must reach not less than 95.0 percent for release. Source: the certificate index, 2026-09-01.
How do you match a vial to its certificate?
Vials ship unlabeled on purpose, with no lot on the glass. Its certificate index (read 2026-09-01) gives one way to pair a vial with its certificate: message support with your order number. Peptara Labs sits on that route, and we haven't placed an order to use it.
What else does it state?
Entity: Peptara Labs LLC, registered in Wyoming, Filing ID 2026-002031026, 30 N Gould St Ste 66115, Sheridan, WY 82801, per the trust page (read 2026-09-01).
Terms: a 60-day guarantee from delivery, covering verified purity, the certificate and fulfillment. You can have a vial tested at an outside lab, with a full refund if it doesn't match the certificate or the order was mishandled. It's about quality, with no promise about health.
Service: worldwide in 5 to 10 business days, tracked; Vietnam in 1 to 3 days free; same-day in HCMC. A small team of expats and locals in Ho Chi Minh City, plus USA and Vietnam offices (homepage, read 2026-09-07).
All of this is Peptara Labs' own statement. We haven't ordered or timed anything.
Sources: the trust page, and the homepage.
What this page doesn't say
No rating, stars, review figures or verdict about Peptara Labs, and no other supplier. Every sentence is either a line from a Peptara Labs page with its read date, or a note on what we did and didn't do.
Is Peptara Labs support run by people or bots?
People, it says: real-human support is one of the claims on the Peptara Labs homepage (read 2026-09-07). We haven't messaged support, so we print it as Peptara Labs' claim, not something we tested.
Research use: our rows describe public pages and documents, never people, and we give no medical advice. Compounds named on this site: research-grade material with no approved human use.
