Public COA audit
Melanotan II
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 88
- Confidence
- 92%
- Panels
- 2/7
- Purity (printed)
- 99.8%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), and 1 soft concern. To improve: include identity, purity, and endotoxin at minimum.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Tested · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
FTIR sample spectrum confirms the presence of Melanotan II with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.8%
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Not on this certificate file
Bioburden / microbial limits testing.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Endotoxin
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Sterility
Not on this certificate file
Sterility testing where applicable.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High HPLC purity
99.8% purity by HPLC (USP <621>) exceeds ≥98% specification. This is normal for research-grade peptides.
Identity confirmed
FTIR spectrum confirms Melanotan II presence with excipients/fillers noted. HPLC chromatogram shows single dominant peak at 6.284 min retention time.
Batch information complete
Lot number WL-ML10-P00518, BT Sample ID 005000040403800, labeled content 10 mg, actual potency 10.7 mg (107.3%), peptide-to-excipient ratio 1:4.3 within recommended range.
Dates valid
Date tested 2026-06-08, issue date 2026-06-12. Both dates are on or before the authoritative current date of 2026-09-05 and show appropriate 4-day turnaround.
Lab information present
BTLabs, 5730 Corporate Way Suite 220, West Palm Beach, FL 33407. Contact info and website provided. Dual scientist signatures (Andrea Castro AS, Verna Zheng AS). QR code present for verification.
Limited scope testing
This COA explicitly states it does NOT provide information on particulate matter, microbial contamination, or presence of endotoxins. This is a purity/identity-focused report. Endotoxin, sterility, microbial, heavy metals, and residual solvent testing are not included in this document.
Professional presentation
Report includes header/footer with report number IF-824-QSA-TR006-BTL2718-07, revision 1.0 January 2025, page numbering (1 of 2, 2 of 2), visual description of sample, FTIR spectrum, HPLC chromatogram with peak table, and USP method references.
