Our mission with VP is to make these high grade research materials accessible with reliable consistency, full transparency, and trust in our products. We send every batch to a third party testing to lab to verify the quality is up to standard.
With over 60+ published lab reports (and many more unpublished), you can rest assured that we don’t cut corners with testing like using old lab reports on a different batch. We have the most recent and up-to-date test results in the industry as you’ll find in our extensive archive of lab reports on the Lab Tests page.

Tested for weight, not just purity.
Many online lab reports only include the purity result with no quantity analysis, so it may show 99% purity, but a 5mg vial may contain just 1mg of active peptide or worse, containing double the quantity creating a dangerous situation for researchers when planning their protocols.


Other online lab reports sometime are self branded or vague with no labeled information of the lab and no way to check legitimacy of their testing. In other cases, some vendors claim lab testing, but a report is nowhere to be found. Additional questionable lab reports are generic ones provided by the manufacturer. They look something like this:

We send every batch of peptides to a reputable and unaffiliated third party analytical testing lab recognized by the research community. You can find a batch number on the product label and lab report to match, as well as a unique key at the bottom of the report to verify the lab report is authentic with our testing lab. Contact us to find out how to verify our lab reports!

Our most recent failed lab report was for a new batch of AOD-9604 5mg.
It tested 99% pure, but only 1mg detected.

Here’s an example where AOD-9604 had double the expected quantity tested at 12.7mg instead of 5mg!
