Every Batch Tested. Every Test Shared.

Lab Image of Man

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.

May 2025

Shipping is slow during times of high tariffs. June will have our final vendor evaluations. 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.

April 2025
