Full Transparency
We believe you should know exactly where your peptides come from and how they are verified before they reach you. Here is our complete process.
Step-by-Step
Every order moves through the same process, start to finish.
We source from established manufacturers and re-verify supplier relationships on an ongoing basis. We request full manufacturing and analytical documentation from every supplier. Independent verification of what we receive is a programme we are building, not one that is running yet.
We rebuilt our testing programme in 2026. We previously published Certificates of Analysis supplied by our vendor and have withdrawn them, because their verification keys could not be independently checked. We now test samples we buy and submit ourselves, and we publish each report as it arrives.
Vials are secured against transit damage. Every order goes out in plain, discreet packaging with no branding or contents indication. Orders before 2 PM EST ship same day.
Certificates of Analysis
Our first Certificates of Analysis from our own testing are now published, starting with Tirzepatide 60mg. The ones we used to show came from our supplier, and their verification keys could not be checked independently, so we took them down rather than imply a level of proof we could not deliver. We test our own inventory, and results are published on our Lab Testing & Verification page as they land — including any that fail.

Can I see a Certificate of Analysis before I buy?
Yes, for the products we have tested so far. Each report is listed on our Lab Testing & Verification page with a link to verify it on the laboratory’s own site. We withdrew the supplier-submitted certificates we used to show because they could not be independently verified; the reports we publish now come from samples we buy and submit ourselves. If you want the current testing status of a specific compound before you order, ask us and we will tell you plainly.
Who does the third-party testing?
Our results come from an independent analytical laboratory, Janoshik Analytical, that we commission and pay directly, so the report carries our name rather than a supplier’s. Each is published with the lab name, test date and batch number.
How will I know what is in my package?
The outer packaging is plain and discreet – no brand name, no contents description. Inside, your order is properly labeled with product and batch information.
Why is PTW different from other peptide vendors?
We built this business because we were skeptical buyers first. Our process is documented, our testing position is stated plainly rather than dressed up, and our support team is reachable. Read the Lab Testing & Verification page and reach out with any questions before you order.
