- Batch-Specific CoA
- Provided with every order, third-party verified, includes HPLC chromatogram + MS data
- Generic CoA shared across orders, often outdated
- No CoA, or fabricated documents with inconsistent batch numbers
- CoA traceability to your specific vial is the single strongest authenticity marker. Generic documents are worthless
- Synthesis Transparency
- FDA-registered 503B facility, synthesis date disclosed, amino-acid sequencing verified
- Vague 'international lab' claims, no facility registration
- No synthesis information, pre-mixed solutions common
- 503B registration is public record. Verify it before purchase or assume unregulated production
- Pricing Per 5mg Vial
- $195–$245 (reflects actual synthesis cost)
- $120–$160 (below cost. Indicates underdosing or substitution)
- $60–$100 (impossible at legitimate purity)
- Peptide synthesis has a floor cost. Pricing below $180/vial for mazdutide signals compromise in purity, sterility, or authenticity
- Purity Verification
- 96–99% via third-party HPLC, chromatogram provided
- '98%+' claimed, no supporting data
- '99.9% pharmaceutical grade' (fabricated claim)
- Legitimate research peptides test 95–99%. Claims above 99% without GMP certification are false
- Reconstitution State
- Lyophilised powder only, requires mixing
- Often pre-mixed or liquid form
- Pre-dissolved or suspiciously uniform powder
- Pre-mixed peptides indicate improper storage or counterfeit. Real mazdutide ships lyophilised and requires reconstitution
- Customer Support Response
- Batch verification provided within 24 hours, synthesis records available
- Slow response, vague answers, 'proprietary' excuses
- No response, or defensive when asked for documentation
- Legitimate suppliers welcome verification requests. Evasiveness is a red flag
