3rd Party Testing
At PeptiBros, quality isn’t a claim — it’s something we verify.
Every batch we supply is independently tested to confirm purity, identity, and consistency before it reaches our customers.
What We Test For
Each product undergoes third-party analysis to ensure:
• Purity levels meet or exceed ≥99%
• Correct compound identity
• Batch-to-batch consistency
• Absence of contaminants
Testing is performed using industry-standard methods such as RP-HPLC.
Certificates of Analysis (COA)
Every product comes with a Certificate of Analysis (COA).
This document outlines:
- Purity results
- Testing method used
- Batch-specific data
We believe in full transparency — if you want to review a COA before purchasing, simply reach out and we’ll provide it.
Why It Matters
In this space, not all products are created equal.
Third-party testing ensures:
- You receive exactly what’s listed
- Consistent quality across batches
- Confidence in your research materials
No guesswork. No shortcuts.
Our Standard
We only work with suppliers who meet strict manufacturing standards, including GMP-compliant processes and certified facilities.
Every batch is checked before being made available — nothing is shipped without verification.
