Every Batch Tested. Every Test Shared.
At Peprion, we believe transparency is non-negotiable. Every batch we produce is traceable — from manufacturing through testing to final delivery. Each lot is assigned a unique batch code, undergoes HPLC analysis at manufacturing and independent testing by trusted third-party labs like Janoshik and Trustpointe Analytics , and is logged with complete documentation. Test results are posted here for your review. We’re committed to delivering research-grade purity you can verify — not just trust.

The batch ending in FR was a vendor considered for Sema. Turns out it the peps sat in a hot warehouse for 5 months, when I asked about the Reta results. We obviously didn't move ahead due to the results and lack of disclosure. Note the odd peaks for the Reta. Each test had 3 vials for review. GET YOUR PEPTIDES TESTED!!

I'm very pleased with the (slow) progress. I'm using Peptide Test / Trust Pointe Analytics for my vendor selection. I will use both Janoshik and Peptide Test for production.

Initial round of vendor qualification testing. All pre-production batches tested independently by Peptide Test.
