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.

August 2025

In August 2025, we finalized the selection of our production manufacturer after a thorough evaluation process focused on quality, reliability, and capacity to scale. The first round of production is now underway, with delivery scheduled for September 2025. Independent lab testing is in progress, and we’ll be posting the full results soon to ensure complete transparency and confidence in our products.

July 2025

July was a slow month. The peptide manufacturing market is strange to say the least, the combo of crack down, tariffs and uncertainty, made what I thought would be a 3 month process take close to 6 months, and counting...

June 2025

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!!

May 2025

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. We purchased some test peptides from a well known Hong Kong based.

April 2025

April marked the beginning of our journey through the Chinese supply chain. Our first vendor turned out to be a trading company rather than a true manufacturer, which taught us an important early lesson. All pre-production batches were still tested independently by Peptide Test to ensure quality. Moving forward, even for customer's buying small quantiies, it’s best practice to request the vendor’s business license and other relevant documents before sending significant funds.
