Third-Party Verified
Lab-Tested Research Peptides in the USA
Every peptide we ship is independently HPLC + MS + endotoxin tested by Verum Analytics (Switzerland). Batch-matched Certificate of Analysis in every box. Public COA library, no login required.
About This Compound
Third-party testing is not optional at BioInfinity — it is the release gate for every batch. After we synthesize, purify, and lyophilize a peptide at our Manhattan facility, a retained sample of the lot is sent to Verum Analytics in Bern, Switzerland for independent verification. The resulting Certificate of Analysis is signed, dated, and matched by batch/lot number to the vial you receive.
The Verum COA reports four release-gate specifications: reverse-phase HPLC purity (≥99% area under the 214 nm peak), ESI mass-spectrometry identity confirmation (within ±0.5 Da of theoretical), endotoxin content (LAL assay, < 0.5 EU/mg), and — where relevant — copper coordination (ICP-OES for GHK-Cu) and salt form / counterion. Any batch that fails any specification is rejected and does not ship.
Every finished COA is publicly browsable in our /coa-library. There is no login gate, no email opt-in, no "request access" button. Every vial carries a batch verification code printed on the label; entering it in the COA library resolves to the exact PDF for that lot.
This is the level of transparency the research-peptide market has historically lacked. If a supplier will not tell you which independent lab tested a batch, or will not let you see the COA before you buy — that is the entire reason we built the public /coa-library.

Frequently Asked Questions
Who tests BioInfinity peptides for third-party verification?▾
Verum Analytics, a contract-testing laboratory in Bern, Switzerland. Every batch we release is HPLC purity + MS identity confirmed by Verum. The resulting COA is signed and matched by lot/batch to the vial you receive.
What does 'lab-tested' actually include on every BioInfinity peptide?▾
Four release-gate tests: (1) reverse-phase HPLC purity (≥99% at 214 nm), (2) ESI mass-spec identity (within ±0.5 Da of theoretical), (3) endotoxin content by LAL (< 0.5 EU/mg), and (4) — for copper peptides — ICP-OES copper coordination verification.
Can I see the COA before I buy?▾
Yes — every batch's COA is publicly browsable in /coa-library. No login, no email gate, no 'request access' step. If a supplier will not show you a COA before purchase, that is a red flag.
Can I verify the COA for the specific vial I received?▾
Yes. Every vial carries a batch verification code on the label. Enter it at /coa-library and it resolves to the exact PDF for that lot — signed by Verum Analytics, dated, and matched to your batch number.
What happens if a batch fails a release-gate test?▾
It is rejected and does not ship. Failed batches are physically destroyed and a new synthesis is queued. We do not repackage failed lots or ship batches that do not meet ≥99% purity.
