Ascension Peptides looks like an operating US vendor with a well-built COA library: 85 records you can search by batch or lot, and no FDA warning letter on record as of September 26, 2026. Its gaps are disclosure and independent data. The site names no legal entity, address or lab, and Finnrick has no tests for it. Its overall score is 8.1/10; on our transparency method alone it scores 7.4/10 and sits at #5 in our editors' order, which weighs partnership terms as well as the rating.
Notice: Ascension Peptides' products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal consumption. This review covers supplier transparency only. We didn't buy or test any products.
Ascension Peptides at a glance
- Operating status: Live storefront at ascensionpeptides.com, checked September 26, 2026.
- Contact: a phone number, (303) 518-6550, and a sales email. The site names no legal entity or street address. A third-party review lists an address in Castle Rock, CO, and says the company was founded in 2024. We couldn't confirm either on the vendor's site.
- Terms: the terms of use give Kansas City, Kansas as the governing jurisdiction and require buyers to be 21 or older.
- Catalog: 41 products in the shop, mostly named compounds plus stacks such as "Wolverine," "GLOW" and "KLOW."
- FDA record: No warning letter found in the FDA database.
Ascension Peptides COA: what's published
The Certificates of Analysis page is a searchable database with 85 COA records. You can filter by product name, SKU, batch/lot, cap color, purity and date, so if you have a lot number from a vial you can go straight to its certificate.
The COA page doesn't name the lab, but product pages now do. As of September 26, 2026, product pages list the lab for each batch. The BPC-157 10 mg page shows Kovera Labs (batch 12-05260628, tested July 10, 2026) and MZ Biolabs (batch 12-01260229, tested March 6, 2026). Independent reviewers had already identified MZ Biolabs:
- Project Biohacking (last reviewed September 1, 2026) identifies MZ Biolabs, "a third-party analytical laboratory in Tucson, Arizona," using HPLC-UV-MS. It says the certificates include the lot number, analysis date, purity result and analyst name.
- PepPal (August 2026) names MZ Biolabs and SafeCert Labs.
We found no link to a lab-side verification tool on Ascension's site. See how to read a peptide COA for how to check a certificate with the lab.
Independent testing
Finnrick shows 0 tests and says "Not enough classifiable tests to rate this vendor yet" (checked September 26, 2026). The only purity evidence is the vendor's own commissioned COAs. See Janoshik vs Finnrick.
Labeling
The research-use framing is strict. The site says products are "for Research, Development use only" and "Not for Human consumption of any kind," uses a 21+ age gate, and its terms say products are for "IN-VITRO LABORATORY RESEARCH USE ONLY." We found no health claims on the homepage.
The deductions:
- Code-named products. Six items are listed only as codes: C-10, R-10, R-30, S-5, T-10 and T-30 (shop). In its August 2026 letter to Peptide Partners, FDA identified similar abbreviations as GLP-1-class drugs. Project Biohacking also reports a semaglutide certificate from Ascension. We cover GLP-1-class products for research use only, with no dosing content.
- Stack names such as "GLOW" lean toward benefit-style branding, though less than the category names we saw elsewhere.
Background: FDA peptide regulation in 2026.

Even so, the picture is mixed against the median across the vendors in our price index: the GLOW and KLOW blends, BPC-157, GHK-Cu and NAD+ came in below it, while ipamorelin, TB-500, MOTS-c and epitalon ran well above.

Is Ascension Peptides legit?
Ascension Peptides appears to be an operating vendor, with an 85-record COA library searchable by lot and no FDA warning letter on record as of September 26, 2026. But it publishes no legal entity or address, and there are no independent Finnrick tests to check its certificates against.
Our scam check, as of September 26, 2026:
| Check | Result |
|---|---|
| Live storefront | Yes, ascensionpeptides.com (checked September 26, 2026) |
| Business entity/address published | No: a phone number and email only; a third-party review lists a Castle Rock, CO address we couldn't confirm |
| Domain age (WHOIS) | Registered September 26, 2023 (WHOIS, checked September 26, 2026) |
| Named testing lab | On product pages: Kovera Labs and MZ Biolabs per batch; not on the main COA page |
| Lot-matched COAs | Yes: 85 records searchable by batch/lot (COA library) |
| Independent tests (Finnrick) | 0 tests, not rated (Finnrick) |
| FDA warning letter | None found (FDA database) |
| Trustpilot | No Trustpilot page; Trustpilot says the profile was removed for going against its guidelines (checked September 26, 2026) |
| Reddit discussion | Little discussion found in a site:reddit.com search (September 26, 2026) |
These checks cover disclosure and public records only. They don't test what's in the vial, which is why we weight independent testing in our score.

Alternatives
- Peptide Plugs (7.5/10): Freedom Diagnostics COAs with accession codes you can check at the lab.
- NextGenPeps (8.8/10): names Janoshik and BioRegen on every COA entry and publishes its LLC and address.
- American Peptides (9.1/10): lot-number COA lookup and a lab named on its homepage.
- Alpha Pro Peptides (6.3/10): lot ID, purity and net content on each certificate.
- Swiss Chems (6.5/10): Finnrick data and a long history, but an FDA letter.
- PSPeptides (8.5/10): dated COAs and wide payment options, but dosing guides on its blog.
Verdict
Ascension Peptides scores 8.1/10. Its lot-searchable COA library is one of the easier ones to use. Naming its lab on its main COA page (it now does on product pages), replacing code names with compound names, publishing a legal entity and address, and getting independent Finnrick data would each lift its score.
