Certificates, per batch
A purity claim without the document behind it is just a number. Here is what we publish, and when.
HPLC purity
High performance liquid chromatography, reported as issued by the testing lab.
Identity
Mass spectrometry confirming the compound is what the label says it is.
Lot traceability
Every certificate names the lot it belongs to, so it can be matched to your vial.
Independent lab
Testing is run by a laboratory Vantra has no ownership interest in.
Published certificates
This table fills in as each batch clears testing.
| Compound | Lot | Released | Purity | Certificate |
|---|---|---|---|---|
|
Awaiting the first batch release. No certificates are published yet, so no compound is marked documented. |

We would rather show an empty table than borrow someone else's paperwork. If you need the analysis for a specific lot before it appears here, email vantrapeptide@proton.me.
How to read a certificate
A certificate of analysis is a lab's report on one specific batch. It is worth knowing what to look for, because the useful parts are not the big number at the top.
The lot number. This is the whole point. A certificate that does not name a lot cannot be tied to the vial in your hand, so it tells you nothing verifiable about what you received. Match the lot on the certificate to the lot on the vial before reading anything else.
Who issued it. A report from a lab with no ownership relationship to the supplier is evidence. One produced in-house is a self-assessment. Both can be honest; only one is independent.
Purity by HPLC. High performance liquid chromatography separates the sample into its components and reports the target compound as a percentage of the total. It answers "how much of this is the thing", not "what is the thing".
Identity by mass spectrometry. This answers the other half, by measuring molecular mass against what the named compound should weigh. Purity without identity is incomplete: it tells you a sample is clean without telling you what it is clean of.
The date. A certificate describes the batch at the time it was tested. It is not a statement about material synthesised later.
Why this page is empty
Vantra has not released a lot yet, so there is no certificate to publish and nothing to put in the table above. Every product page reads "Pending" for purity for the same reason. A page like this one filled with figures from batches you cannot buy would be worse than an empty one.
