Lab Testing and Certificates of Analysis

Every research peptide Regenwell PH sells is a white lyophilised powder in a sealed vial. From the outside, a 99.9% pure vial and a mislabeled one look identical. The only way to know what is in a vial is an independent laboratory test, and the only way for you to trust that test is to be able to open it yourself. This page explains how our testing works, what we publish, how to read a certificate, and what to do if the certificate you want is not yet listed.

What we publish

Certificates of analysis are listed on the Certificate of Analysis page. Each is hosted on the independent testing platform under its own certificate ID, so you open the lab's record rather than an image we control. The current tirzepatide certificate (ID a6cyap3, Finnrick platform) reports 99.90% purity. Certificates for further compounds are added to that page as each batch's results are returned; if the compound you are ordering is not yet listed, message us with the product name before you order and we will send the current batch result or tell you plainly that it is pending.

How the testing works

  1. Sampling. A vial from the batch is sent to an independent testing service.
  2. Purity. High-performance liquid chromatography (HPLC) separates the sample and reports what percentage of it is the target peptide. A purity figure of 99% or higher is the standard we expect for research-grade material.
  3. Identity. Where the certificate includes identity testing, mass spectrometry confirms the molecular mass matches the target compound. Purity without identity only tells you the sample is "mostly one thing"; identity tells you which thing.
  4. Publication. The lab hosts the certificate under a unique ID. We link to it. We do not retype the numbers.

How to read a certificate

  • Compound name should match the product you are buying, not a related compound.
  • Purity is a percentage. Look for the method (HPLC) and the figure.
  • Identity or mass confirms the molecular mass against the expected value.
  • Quantity, where reported, shows the measured milligrams in the vial against the label claim.
  • Certificate ID and platform. If you cannot open the certificate on the lab's site by its ID, treat it as unverified.

What a certificate does not tell you

A certificate describes the sampled vial from that batch at the time of testing. It does not describe how the supplier stored the batch afterwards, how it was shipped, or how you store it after delivery. That is why our product pages give storage guidance and why vials are packed against breakage and shipped by tracked courier. Handling after the certificate is your responsibility and ours together.

Why this matters in the Philippines specifically

Demand for tirzepatide, retatrutide and cagrilintide has drawn sellers into the market who publish no testing at all, or who reuse a single certificate image across every product. Our guide to spotting fake or mislabeled peptides and the six-point sourcing checklist show how to check any supplier, including us.

Request a certificate

Message us through the contact page with the product name, or with your order number after purchase, and we will send the batch certificate. Questions about reading a certificate are welcome in the WhatsApp research community.
