Mass spectrometry says what's actually there. We test the peptide, measure the purity, weigh the contents, and screen for endotoxin, microbes and fentanyl — then publish every result, pass or fail, with the vendor named.

Each test answers one thing a label can't. Method and limit are printed on every result.Each test answers one thing a label can't. The method and detection limit are printed on every result, so you can compare our numbers with anyone else's.

| Test | What it answers | Method | Reported as |
|---|---|---|---|
| Identity | Is this molecule the peptide on the label — not a cheaper analog with a similar name? | LC-MS/MS Shimadzu triple quadrupole | observed m/z, charge state, calculated mass vs expected |
| Purity | How much of what's in the vial is that peptide, versus truncated chains, deletions and leftover synthesis reagents? | HPLC-UV / DAD 214 nm, gradient | main peak % area, with the chromatogram |
| Content | Does a "10 mg" vial contain 10 mg? | Gravimetric calibrated balance, tare and gross | mg found vs mg on label, as % |
| Endotoxin | Is there bacterial endotoxin — the pyrogen that causes fever and reactions — in the vial? | LAL kinetic chromogenic | not detected at 0.01 EU/mL, or the value found |
| Microbial screen | Is there bacterial, fungal or viral DNA/RNA in the vial? | PCR per target panel | detected / not detected, per target |
| Fentanyl | Is there fentanyl or a fentanyl analog present? | LC-MS/MS targeted | not detected at 0.5 ng/mL, or the value found |
Identity, purity and content are included in every test. Endotoxin, the microbial screen and fentanyl are add-ons. How each test works, and why two labs can disagree.
Every result is public. Including the fails.Every result is public. Including the ones vendors wish weren't.
The registry is the product. A lot that fails is published with the same detail as one that passes, and the vendor can post a response underneath it.

Every vial gets an accession number the moment you order. That number follows it through the lab and onto the result, so nothing is ever confused with anything else.

Things we will never print on a result.
A test is only as honest as its wording. These phrases sound reassuring and mean nothing, so they don't appear here.
- "Endotoxin free"
- No assay can prove zero. We report not detected at 0.01 EU/mL — the cutoff is the claim.
- "Sterile"
- Sterility is a pharmacopeial test on a whole batch. We run a PCR screen on one vial and call it exactly that.
- "99% pure" without a chromatogram
- The number comes with the trace it was integrated from, so you can see the peaks we counted and the ones we didn't.
- "Safe" or "effective"
- We report what is in the vial. We don't give dosing, medical advice, or opinions on whether you should use it.

Earned per lot, never per vendor.The seal is earned per lot, never per vendor.
Identity confirmed · purity > 98% · contents ≥ 90% of label · endotoxin not detected. Scan the seal on any vial and it opens the data.A lot is Vialidated when, on that lot, identity is confirmed by mass, purity is greater than 98%, contents are at least 90% of the label, and endotoxin is not detected at 0.01 EU/mL. Three tests; the three icons in the seal. The next lot starts from zero. Scan the seal on any vial and it opens the data it was awarded on.
Vendors with a volume agreement are listed as Preferred Partners. That is a commercial relationship and is always labeled as one — it never changes a result.
