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 Selank with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.8%
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High HPLC purity confirmed
99.8% purity by HPLC (USP <621>) meets specification of ≥98%. This is normal for research-grade peptides.
Identity confirmed by FTIR and HPLC
FTIR spectrum confirms Selank presence with excipients. HPLC chromatogram shows single dominant peak at 1.808 min retention time.
Batch and sample information complete
Lot number WL-SK10-P00519, BT Sample ID 005000040403809, labeled content 10 mg, actual potency 11.2 mg (112.3%).
Testing and issue dates appropriate
Date tested: 2026-06-08, Date issued: 2026-06-12. Four-day turnaround is reasonable.
Testing lab identified with contact information
BTLabs, 5730 Corporate Way Suite 220, West Palm Beach, FL 33407. Website: https://btlabtesting.com. Two scientists signed (Andrea Castro, AS and Verna Zheng, AS).
Limited testing scope
COA explicitly states it does not provide information on particulate matter, microbial contamination, or endotoxins. No heavy metals, sterility, or residual solvent testing performed. This is common for basic peptide identity/purity testing but limits comprehensive quality assessment.
Professional presentation with supporting data
Report includes QR code, report number IF-824-QSA-TR006-BTL2718-10, visual description of sample, FTIR spectrum, and HPLC chromatogram with peak data. Formatting is consistent and professional.
