Here are some trusted companies I found who had it together. Not all peptide companies are equal and here’s what you’re looking for .
Excellent
- GMP manufacturing
- ISO 13485
- Third-party COAs for every batch
- Independent HPLC purity testing
- LC-MS identity testing
- Sterility testing
- Endotoxin testing
- Batch number on every vial
- Transparent lab reports
One point I’d definitely make is that a Certificate of Analysis (COA) alone doesn’t prove a product is high quality. A COA is only as trustworthy as the lab that issued it. Stronger evidence comes from:
- Independent third-party testing
- Batch-specific reports
- Identity testing (e.g., LC-MS)
- Purity testing (e.g., HPLC)
- Sterility and endotoxin testing for injectable products
