Accumark Labs is an Anaheim, California lab that tests research peptides by HPLC at a flat $250 per sample and gives every report a code you can check on its site, but its ISO/IEC 17025 accreditation is listed as "Pending" as of October 21, 2026. Four vendors in our directory cite it.

Who Accumark Labs is
The homepage names the operator as Valence Analytical LLC, doing business as Accumark Labs, and calls it a "US-Based Laboratory." It lists a phone number and an info@ email but doesn't name a lab director or staff. We didn't find a state filing we could confirm, so ownership details beyond the DBA are left out.
There are other businesses called "Accumark." The one that signs peptide COAs uses the accumarklabs.com domain, which is printed on the reports vendors post.
What it tests
The services page lists:
- Core Panel: HPLC identity confirmation, purity (%) and quantity (mg), with a digital and PDF certificate.
- Endotoxin (LAL): bacterial endotoxin quantification, as an add-on.
- Sterility (PCR): described as "Rapid microbial detection," as an add-on.
- AccuShield Panel: the core panel plus both add-ons.
It says the flat rate covers 51 peptides and compounds. LC-MS identity, residual solvents, residual moisture and NMR are listed as in development, not yet offered. So for now, the core panel's identity check is HPLC-based, with mass-spec identity still on the roadmap.
Accreditation
Accumark doesn't claim ISO/IEC 17025 accreditation yet. The homepage shows "ISO 17025" with the status "Pending." It names no accrediting body or certificate number. You can watch for a listing in the A2LA, ANAB and PJLA directories.
Pricing and turnaround
As listed on the shop page on October 21, 2026:
| Option | Price |
|---|---|
| Core Panel (identity, purity, quantity) | $250 per sample |
| Endotoxin (LAL) add-on | $200 |
| Sterility (PCR) add-on | $230 |
| AccuShield Panel (core + both add-ons) | $578 ($680 before a 15% bundle discount) |
| First-sample offer | 50% off one sample, up to $125 |
The headline turnaround is "48-72 Hour," and the shop says standard results typically arrive in two business days after the sample is received.
How to verify an Accumark Labs report
- Find the verification code on the COA. Codes follow an XXXX-XXXX pattern.
- Go to the verify page and enter it. The page says: "Enter the verification code from your Certificate of Analysis."
- Each report also has its own URL at accumarklabs.com/verify/ plus the code. Accumark says reports are "cryptographically signed."
- Compare compound, lot, dates and results with the vendor's copy.
Check the PDF, not the label. On October 21, 2026, Zeptix Labs' COA page listed its Tesamorelin 10mg report under Accumark, but the PDF itself carries the Freedom Diagnostics header. A Zeptix GHK-Cu 50 mg report did carry Accumark branding and a code in the expected format. Vendor pages can mislabel which lab issued what, so look at the report header. Our COA checklist walks through the other checks.
Vendors in our directory that cite Accumark Labs
From our vendor data as of October 21, 2026. "Lot-matched" and "Endotoxin" describe each vendor's COA program overall, not only its Accumark reports.
| Vendor | Lot-matched COAs | Endotoxin data | COA page |
|---|---|---|---|
| Zeptix Labs | Yes | Not confirmed | COA page |
| Peptides Source | Yes | Yes | COA page |
| Warrior Makers | Not confirmed | Yes | COA page |
| FRO Peptides | Yes | Yes | COA library |
Peptides Source names Accumark among four labs and says Accumark certificates carry a QR code, but its page doesn't tag individual certificates by lab.
What an Accumark Labs COA does and doesn't prove
What it can show:
- The HPLC purity and measured quantity of the sample Accumark received, on the test date.
- That the report is genuine, if the verification code returns a matching record on accumarklabs.com.
What it can't show:
- That your vial matches. Only a matching lot number ties a report to your batch.
- Mass-spec identity. The core panel uses HPLC. Without MS, a closely related compound could be harder to rule out. See HPLC purity explained.
- Endotoxin or sterility, unless those add-ons appear on the report. Our endotoxin guide explains why that matters.
- Independent sampling. Vendor-commissioned tests use samples the vendor sends. That's different from blind testing of retail vials.
- Accredited quality. The lab's ISO 17025 status is pending, so there's no outside audit of its quality system yet.
