How Curo Tests Every Lot

Third-party tested peptides, what that means at Curo

Third-party tested means the laboratory that tests the lot is independent of Curo and of the manufacturer. Curo sends every production lot to an independent U.S. laboratory and publishes the result before the lot is listed. The report is tied to the lot number on the vial, so a lab-tested claim can be checked, not taken on trust. Search any lot in the COA library or compare current peptide prices against the purity on each lot.

The standard

Every Curo production lot is tested by an independent laboratory. Curo publishes each lot's certificate of analysis on the product page and in the COA library. Researchers can search COAs by lot.

What each COA reports

  • Identity (LC-MS) confirms whether the measured molecular mass matches the expected compound.
  • Purity (HPLC, % area) reports the target compound as a percentage of total detected peak area.
  • Fill (mg per vial) reports the measured amount of material in each vial.
  • Endotoxin (where available) reports the measured bacterial endotoxin level for the tested lot.
  • Sterility (where available) reports whether the tested lot showed microbial growth under the laboratory's sterility test.

Where the data lives

  • The COA library provides a per-lot lookup for published reports.
  • Product pages include lot cards and compound identifiers. See the BPC-157 5mg product page as an example.
  • The data license makes Curo's published chemical and analytical data available for reuse under CC BY 4.0.

Reading a COA

  • Find the lot number printed on the vial label.
  • Enter that exact lot number in the COA library.
  • Confirm the compound and fill match the vial label.
  • Review the identity, purity, fill, and endotoxin results.

Common questions

Are Curo peptides third-party tested?
Yes. Every production lot is tested by an independent laboratory, and the certificate of analysis is published on curo.you.
What does each lot test cover?
Identity by LC-MS, purity by HPLC, fill in mg per vial, and endotoxin and sterility where available.
Where can I see the test for my vial?
Find the lot number on the vial label and enter it in the COA library. The report shows the results for that exact lot.
