We replace editable PDF attachments with rigorous 4-stage analytical testing (zero corners cut), dual PhD and MD sign-off, and an unfalsifiable blockchain transaction record.
COAProof was built to fix the four biggest ways fake or edited lab certificates trick peptide buyers and clinics.
Anyone can open a normal PDF file and change a purity score, lot number, or brand name in two minutes. Because normal PDFs use editable text layers, bad sellers can easily hide failed tests or fake a new date.
Many sellers repost public group-test PDFs that belong to another company or an old batch. Looking at a plain PDF screenshot gives you no way to know if your vial came from that tested batch.
Most lab websites let bots download every report in a public list. Copycats can guess simple report numbers, steal supplier lists, and repost someone else's lab test as their own.
Many labs cut corners by running a quick single-pass purity check without testing real milligram fill weight, molecular identity, or bacterial safety, and then store the result in an editable database.
See how COAProof delivers the most advanced COA verification and the highest level of compliance for peptide and research labs.
| Compliance Dimension | Ordinary PDF COA | COAProof Blind Server-Side Standard |
|---|---|---|
| Document Tamper Resistance | ✗ Editable text layers; purity numbers, dates, and lot codes can be altered in two minutes. | ✓ 300 DPI flattened security image with guilloche background plus live server-side HMAC-SHA256 verification. |
| Database & Bot Scraping Protection | ✗ Publicly enumerable task IDs let bots scrape every client report and steal supplier batch lists. | ✓ Blind server-side lookup (like coupon or order validation). Reports only unlock with the exact 8-character batch code. |
| Unfalsifiable Blockchain Record | ✗ Stored in a private, editable web database that can be altered, backdated, or deleted at any time. | ✓ Test numbers are permanently locked in an on-chain blockchain transaction (`SHA-256` hash) for the highest level of trust. |
| Group-Test & Lot Borrowing Prevention | ✗ Unrelated vendors routinely repost public group-testing PDFs from other batches. | ✓ Cryptographic lot binding locking each report to its unique 8-character batch code and immutable blockchain transaction. |
| Rigorous Analytical Protocol (No Shortcuts) | ✗ Single-pass purity check that cuts corners on real peptide weight, identity, and medical oversight. | ✓ Full 4-stage protocol with zero corners cut: RP-UHPLC 214nm purity, LC-MS mass identity, net mg content, USP <85>/<71>, and dual PhD/MD sign-off. |
| Storefront & Researcher Experience | ✗ Blurry static JPEG screenshot uploaded to a product gallery. | ✓ Interactive 3D Optical COA Badge (`<coa-verify-coa>`) + 1:1 Archival PDF download. |
