Quality Assurance
Certificates of Analysis
Batch-specific, independently verified purity documentation for every compound we carry. Each COA includes a task number you can verify directly with the testing laboratory.
How COA Verification Works
Every COA below is independently verifiable — here's how to confirm yours.
1. Find your batch number
Each vial label includes a batch number. Match it exactly to the batch number shown on the COA card below.
2. Check the test report
Note the task number and unique key on the COA card. These link to the independent lab's original report.
3. Verify on the lab's site
Click "Verify on janoshik.com" and enter the task number or unique key. The lab confirms the report is authentic and unmodified.
Batch numbers must match exactly
A COA only applies to the specific batch it was issued for. If your vial's batch number does not match the COA, do not use the product — contact us immediately at support@silverlinelabs.store for the correct documentation.
Testing Scope & Methodology
What we test, how we test it, and what a COA does — and doesn't — guarantee.
What each COA verifies
- • Purity — HPLC (High-Performance Liquid Chromatography) analysis confirming the percentage of the target compound
- • Mass/Strength — Actual quantified mass of the active peptide in the vial
- • Identity — Analytical confirmation that the compound matches its labeled identity
- • Independence — Testing performed by Janoshik, an independent ISO-accredited analytical lab
What a purity COA does not cover
- • Sterility testing — Not included in standard HPLC purity analysis
- • Endotoxin screening — Requires separate LAL testing
- • Microbial contamination — Requires separate USP <71> testing
- • Heavy metals — Requires separate ICP-MS analysis
Important: A high HPLC purity result confirms the chemical identity and concentration of the peptide but does not, by itself, establish that a vial is sterile or safe for injection. These products are sold for in vitro laboratory research only and are not intended for human or veterinary use. Researchers requiring sterility or endotoxin documentation for a specific application should contact us at support@silverlinelabs.store before ordering.
