Pure Rawz lab testing and purity
Pure Rawz lab testing checks every batch to 99% purity or higher, with first- and third-party tests. Here is how the testing works and how to get the certificate for your batch.
What Pure Rawz lab testing checks
Pure Rawz lab testing measures purity, which is how much of the sample is the compound on the label. For peptides the standard method is high-performance liquid chromatography (HPLC). It separates the peptide from synthesis leftovers and shorter fragments, and the result is reported as a percentage.
Pure Rawz requires 99% or higher for every batch. A batch that tests lower isn’t sold. Results come from first-party testing and independent third-party labs.
Batch numbers and certificates
Pure Rawz labels every vial and bottle with the compound, the amount and a batch number. Each batch has a certificate of analysis on file. Email sales@pure-rawz.co with the batch number and we’ll send it.
Pure Rawz lab testing applies across the range, from BPC-157 and Retatrutide to RAD-140 (Testolone) and Semax. Lab supplies such as Bacteriostatic Water are sold sterile and sealed.
What a Pure Rawz certificate shows
Each certificate of analysis we send covers one batch. It lists:
- The compound name and batch number, matching your label
- The test method, usually HPLC for peptides
- The purity result as a percentage
- The test date
How HPLC testing works
A small amount of the sample is dissolved and pushed through a packed column under high pressure. Different molecules travel through the column at different speeds, so they come out at different times. A detector records each one as a peak, and the purity is the main peak’s share of the total. That’s why the result is a percentage.
A purity test answers one question: how much of the sample is the target compound. It’s a reliable way to compare batches, and it’s the number printed on your certificate.
Batch-to-batch consistency
Pure Rawz lab testing also makes batches comparable over time. If a long study runs across two batches, the two certificates show whether purity stayed the same, which helps explain any change in your results.
Why purity matters in research
A study is only as good as what goes into it. Impurities in a peptide are mostly shorter or damaged versions of the same chain, left over from synthesis. They can bind the same receptors weakly or not at all, which makes results harder to repeat. Starting at 99% or higher keeps that noise low, and the batch number lets you record exactly which material you used.
Storing tested compounds
Pure Rawz testing tells you what was in the vial when it was made. Storage keeps it that way. Keep sealed peptides in the freezer, mixed vials in the fridge, and capsules and powders cool, dry and out of light. Each product page has storage notes for its form.
Want to read about the compounds themselves? Every product page links the published studies, and the Pure Rawz blog has longer guides such as BPC-157 and Tesamorelin.
Pure Rawz lab testing FAQ
Is every batch tested?
Yes. Every batch is tested before it’s sold, and anything under 99% isn’t sold.
How do I get the certificate for my vial?
Email sales@pure-rawz.co with the batch number printed on the label.
Does testing cover lab supplies?
Bacteriostatic water and the other lab supplies are sold sterile and sealed. Purity certificates apply to the research compounds.
Pure Rawz products are sold for laboratory research use only. They aren’t for human or veterinary use and haven’t been evaluated by the FDA.
