Every certificate, published in full.
Most sites ask you to trust a badge. We ask you to read the paperwork. Below are the real Certificates of Analysis for the products that have one — issued by two named, independent US laboratories, published in full, one click away.
Average purity is the mean of the fifteen published peptide COAs on this page, measured by HPLC-UV. It is a published figure, not a promise — future production may test differently. Bacteriostatic water is not a peptide and is excluded from the average.
Don’t take our word for it. Read the certificate.
We publish the raw lab reports — not a summary, not a badge image, not a screenshot we made ourselves. Every number on this page is one click from the source document it came from.
Open any certificate below. Check the product name, the purity, the lab’s name. If a seller won’t show you the actual report, ask why.
Read a certificateNever read a lab report before? Here are the assays you will see on our certificates, in plain English. The panel is not the same on every certificate — it varies by compound and by laboratory, so each product below lists only the tests its own certificate actually performed.
Is it the real thing?
the molecule against its known molecular weight. You get the compound on the label — not a substitute.
How clean is it?
The sample is separated and measured to show what percentage is the actual compound versus anything else. Each product’s measured figure is published next to its certificate below — our current verified range is 98.68% to 99.95%.
Is the full amount there?
The vial’s contents are weighed and measured, so the amount in the vial matches the amount on the label.
Does it look right?
A visual confirmation of color and form — for example, a white freeze-dried powder, exactly as it should look.
Each certificate is limited to the assays printed on it, and those assays differ between certificates. Apart from the single BPC-157 10mg certificate that includes them, we make no claim of contaminant, adulterant, fentanyl, heavy-metal, endotoxin, sterility, or microbial testing, and no claim of laboratory accreditation, because the certificates do not cover them. Bacteriostatic water is not sterility tested. All of our testing is performed in the United States; manufacturing origin is not established and we make no made-in-USA claim.
Open any certificate below and check three things. It takes about thirty seconds.
- 01
Find the product name
It should match the product you’re buying — not a different compound or a generic title.
- 02
Check the purity number
Look for the HPLC-UV purity result. Each certificate shows the measured figure, and we publish it next to the link.
- 03
Check the identity line
The LC-MS result confirms the molecule matches the label. That’s the line that says it’s real.
Testing you can’t read isn’t testing.
In this space, many sellers show no testing at all. Others point to a generic certificate that doesn’t match what they actually ship. We think that’s not good enough.
So we do it the plain way: a current, product-specific report for every item we carry, the name of the American laboratory that ran it, and a direct link to the full document. Nothing to hide.
Tested in America — never China or unverified sources.
Our certificates are issued by two independent American laboratories: Freedom Diagnostics Testing in Franklin, Tennessee, and Kovera Labs in Buffalo Grove, Illinois. Both are independent of YouthfulLab and of our supply partner. Neither publishes ISO 17025 or CLIA accreditation, so we describe them only as independent. This concerns laboratory work only — we make no claim about where the material is manufactured.

Kovera Labs certificates carry an access code. Enter it at koveralabs.com/verify and the laboratory confirms the document directly with you — you do not have to take our word for it.
Verify with the lab ↗One certificate goes much further than the rest.
The Kovera Labs report for BPC-157 10mg adds a fentanyl presence analysis (not detected), heavy metal screening for arsenic, cadmium, lead and mercury (all negative), a microbial sterility screen (no growth), an endotoxin safety screen (pass, 0.5 EU/mL or less) and pH 5.6. That panel is rare on a research peptide. It applies to this certificate only — no other product on this page carries it.
Method: RP-HPLC, C18 column, DAD at 214nm. Purity 99.202% against a >98% specification, net content 9.71mg against a ~10mg specification, identity confirmed as BPC-157 by LC-MS.
One COA per product — the most recent document, opened directly as a PDF in a new tab. Products marked Certificate pending have no matching certificate for that exact strength yet, so we link nothing for them.
Test panels vary by compound and by laboratory. Each list shows only what that product’s own certificate performed — nothing is implied for any other product.
