Rejected lots
Not every lot passes. These lots were tested, did not meet our release standard, and were rejected and disposed. None were sold. Each lot’s laboratory report is linked on its card once published. Why we threw away 710 vials
Our testing laboratories
Our first four lots were tested at Vanguard Laboratory in Olympia, Washington. Newer batches are tested at independent U.S. labs. Each lab issues the Certificate of Analysis we publish here, and every report names the lab that issued it.
What we test
Up to ten checks for every batch, never fewer than eight. Full methods and results appear in its Certificate of Analysis.
Purity
Measures the proportion of peptide relative to detectable impurities. The result is reported as a purity percentage.
Quantity
Measures the amount of peptide in the tested sample, in milligrams. This lets you check the amount against the vial label.
Identity
Checks that the sample matches the expected peptide. The result helps confirm that the contents match the product label.
Heavy metals
Screens for heavy metals such as lead, arsenic, cadmium, and mercury. Measures any detected metals to assess contamination.
Endotoxins
Checks for endotoxins produced by Gram-negative bacteria. Measures the amount present in the tested sample.
Fentanyl screening
Screens the sample for fentanyl contamination. Shows whether fentanyl was detected within the test’s detection limit.
Multi-vial conformity
Compares purity and peptide content across several vials from the same batch. Shows how closely the tested vials agree.
Solubility
Checks how the sample dissolves in the lab’s test solution. The lab looks for undissolved material and other visible changes.
Product integrity
Inspects the sample, vial, closure, and seal for visible damage or leakage. Records the condition of the product and its packaging.
Sterility
Checks the samples for bacterial and fungal contamination.
Not all “tested” is the same.
Most local sellers don’t test at all, so purity comes down to which factory vial you get. Some test for purity. We don’t stop there.
Untested seller
No lab report. Purity depends on which factory vial you happen to get.

What this means for your vial Every batch
- Fentanyl screening and sterility on every batch, never skipped.
- At least 8 of our 10 checks, and the COA lists exactly which were run.
- Five vials pulled at random from the production run, not a hand-picked sample.
- Your lot number matches a published report you can verify with the lab.
✓ Yes · ~ Sometimes or unclear · ✕ No. “In our panel” means the check is part of our 10-point panel; each batch’s COA shows the checks it received. Seller columns describe common practice in the Philippine market, not any specific company.
Common questions
Answers about ordering, batch testing, storage and delivery.
Who tests your batches?
Independent U.S. laboratories perform our testing. Our first lots were tested at Vanguard Laboratory in Olympia, Washington, and every report names the lab that issued it.
What are the 10 checks?
Purity, quantity, identity, endotoxins, heavy metals, multi-vial conformity, fentanyl screening, solubility, product integrity and sterility. The batch COA lists the results and methods.
Do you test restocks from the same manufacturer lot?
Yes. Every newly received batch is independently tested before release, including a restock from a manufacturer lot we have already purchased.
Why is purity testing alone not enough?
Purity does not tell you the vial’s quantity, confirm every contaminant is absent, or establish sterility. That is why we check identity, quantity, contamination and the other items in our 10-point panel separately.
What does “testing in progress” mean?
The completed batch report is not published yet. It is not a passing result. We publish the batch COA when testing is complete and do not substitute another batch’s report.
How do I verify my vial and COA?
Find the lot number on your Morris Peppy vial label. Use Verify Product to match that number and the cap color to the batch record, then verify the report with the issuing lab. This helps identify reused or mismatched COAs, but cannot completely prevent fraud.
