Most research peptide suppliers offer no independent testing or basic self-reported testing. We built Elite Certification around what reproducible research actually requires.
Each test targets a specific failure mode that would compromise research integrity. All seven must pass — no exceptions — before a Certificate of Analysis is issued.
High-performance liquid chromatography confirms purity exceeds 98% with no significant contaminant peaks or truncation products. Results are reported as percentage area under the curve at 220 nm, which detects all peptide bonds indiscriminately — not just the target compound.
Amino acid analysis independently verifies the actual peptide mass per vial matches the labeled quantity to within ±5% tolerance. HPLC purity alone doesn't confirm quantity — a 99% pure sample with 30% less peptide than labeled will still pass purity.
Electrospray ionization mass spectrometry confirms the molecular weight and sequence identity of the peptide. Deviations from the expected mass spectrum flag synthesis errors, racemization events, or sequence scrambling that wouldn't be detected by purity testing alone.
Every Certificate of Analysis is hosted on the independent laboratory's servers and encoded into a QR code applied directly to the vial at the time of certification. The QR link is permanent and independently verifiable — no COA can be edited or fabricated after the fact.
Limulus Amebocyte Lysate testing screens for bacterial endotoxins using kinetic turbidimetric method. Endotoxin contamination at sub-visible levels can confound in vitro and in vivo results, triggering inflammatory responses that have nothing to do with the peptide under study.
Inductively coupled plasma mass spectrometry (ICP-MS) screens for elemental impurities including lead, arsenic, cadmium, and mercury under ICH Q3D limits. Heavy metal contamination is a synthesis byproduct risk that standard HPLC testing does not detect.
Microbial contamination screening tests for the absence of viable bacteria, yeast, and mold. Results are reported as colony-forming units per gram. Combined with endotoxin testing, this establishes a complete microbiological safety profile.
Products are labeled and sold under the Research Use Only exemption in FDA 21 CFR 809.30. Labeling explicitly states the RUO designation. We do not market for clinical, diagnostic, or therapeutic use.
All testing laboratories hold active ISO/IEC 17025 accreditation — the international standard for testing and calibration laboratory competence. Accreditation is independently audited.
Analytical test methods reference USP monographs where applicable, including USP <467> for residual solvents and USP <85> for bacterial endotoxins.
Heavy metal analysis uses EPA SW-846 Method 6010/6020 via ICP-OES or ICP-MS. All reference standards are traceable to NIST certified reference materials.
Every product follows the same documented chain of custody from raw material to your vial. No shortcuts at any stage.
Raw material synthesis at a US-based GMP-compliant facility. All synthesis reagents are verified for identity and purity before use.
Finished peptide is lyophilized (freeze-dried) in a controlled environment. Vials are filled and sealed under cleanroom conditions.
Representative samples from every production lot are pulled for third-party testing. Sample size and methodology follow ICH Q6A guidelines.
Samples are submitted to an ISO/IEC 17025 accredited third-party laboratory. Testing against the seven-point panel begins.
Upon passing all seven endpoints, the laboratory issues the Certificate of Analysis with full test data. COA is stored on independent infrastructure.
Each vial receives a QR code cryptographically linked to its lot COA. Only lots that have passed testing are released for sale.
ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. It requires laboratories to demonstrate technical competence, calibrated equipment, validated methods, and impartiality in every test they perform.
Accreditation is granted and annually audited by a national accreditation body — not self-certified. When a laboratory holds ISO/IEC 17025 accreditation, it means an independent auditor has verified every aspect of its testing operation.
Verify a LotA Certificate of Analysis (COA) is a document issued by the testing laboratory that reports the results of all analytical tests performed on a specific lot. It includes the test methods, specifications, actual results, and a pass/fail determination for each endpoint. Our COAs are issued by the accredited third-party lab — not by us.
ISO/IEC 17025 is the only globally recognized standard for testing laboratory competence. Other certifications (ISO 9001, for example) govern quality management systems — they do not certify the technical accuracy of individual test methods. 17025 accreditation requires demonstrating competence method-by-method.
Third-party means the testing laboratory has no commercial relationship with the supplier being tested. They are paid for testing services, not for results. This eliminates the financial incentive to report favorable outcomes. Self-reported testing (in-house) and second-party testing (a contractor hired specifically to confirm a result) do not provide the same assurance.
Any lot that fails any of the seven test points is not released for sale. No exceptions. Failing lots are quarantined, investigated, and the root cause documented. Customers are not affected by failing lots unless they have already ordered from one — in which case we contact them directly.
The QR code on each vial encodes an authentication token that links the physical vial to its lot-specific COA in the verification database. Scanning it takes you directly to the full test report. The token is unique per lot and cannot be reused across vials.
Yes. The full COA with all test data is accessible by scanning the QR code on your vial or entering the lot number at /verify. PDF copies are available on request. We do not modify or summarize COA data — you see exactly what the lab reported.
No, and no research peptide supplier is. Products are sold under the Research Use Only (RUO) designation, which is explicitly exempt from FDA premarket approval requirements for drugs and devices, provided products are labeled and sold exclusively for research. Our labeling complies with FDA 21 CFR 809.30.
We work with Medallion Labs and other ISO/IEC 17025 accredited analytical laboratories for routine panel testing. Laboratory identity is disclosed on each COA.
COAs are hosted on independent, read-only laboratory infrastructure — not our servers. The QR code on the vial links directly to the lab's record, not to a document we uploaded. We cannot modify COA records after issuance.
Yes. Every peptide in the catalog goes through all seven test points. We don't use different standards for different compounds or different price points. The same panel applies to every lot of every product.
