Transparency You Can Trust
Every TONIC LABS peptide comes with a Certificate of Analysis (COA) from an independent, third-party testing laboratory. Our COAs verify:
- Purity — HPLC analysis confirming ≥99% purity
- Identity — Mass spectrometry confirming molecular weight and structure
- Sterility — Endotoxin and bioburden testing where applicable
- Appearance — Visual inspection of lyophilized powder or solution
How to Access COAs
COAs are available in two ways:
- Product Pages — Each product listing includes a downloadable COA for the current batch.
- Email Request — Contact us at coa@stacked.example with your order number or product name and we will send the relevant COA within 24 hours.
We believe transparency is the foundation of trust. If you ever have questions about our testing methodology or results, our team is here to help.
