DSIP certificates of analysis
Every DSIP batch below was tested by HPLC and mass spectrometry at Janoshik Analytical, an independent laboratory. The figures are read from the certificates themselves, and each row carries the key that pulls the original report from the laboratory directly.
2 certificates carrying a purity result, spanning 3 months of production. Measured purity ranges 99.46% to 99.63%, averaging 99.54%. One certificate says a batch was clean; a run of them says the process is.
Measured content against label: across the 2certificates where the tested vial’s label size is known, the laboratory measured an average of 114.7% of the labelled amount (range 107.4% to 122.0%). Rows where the size cannot be read reliably from the certificate show a dash rather than a guess.

“Content tested” is the peptide mass the laboratory measured in the vial it received, reported exactly as printed. It describes that vial, not the retail fill: several sizes are drawn from the same certified bulk lot, so a figure here can differ from the size you buy. Purity is a property of the material itself and applies to every fill from that lot.
Every row also links the report document itself, hosted here so it can be read without leaving the site. That copy is a convenience; the laboratory's record is the authority, and it is the first link in each row. Take any key from the table and enter it at janoshik.com/verification — the laboratory returns the original report. We neither issue nor host these results, which is the point: the confirmation does not depend on our word. Holding a vial and want the certificate for that exact lot? Use the batch lookup.

Common questions
- How do I verify a DSIP certificate myself?
- Every row below carries the verification key printed on that certificate. Enter it at janoshik.com/verification and the laboratory returns the original report. Lyra Vital does not host or issue the result, so the confirmation does not depend on us.
- Who performed the DSIP testing?
- Janoshik Analytical, an independent laboratory. The tests were commissioned by the manufacturer rather than by Lyra Vital, and each certificate names both the laboratory and the batch it covers. In October 2026 Lyra Vital also sent sealed retail vials to Janoshik in its own name; those reports are added to the matching certificate page, marked Ordered by Lyra Vital, as they are issued.
- What does the purity figure measure?
- HPLC purity for the batch named on that certificate. It is the figure printed on the document, not a specification or a target. Where a certificate also reports measured peptide content, that is shown alongside it.
- Why does the content tested differ from the size I buy?
- The content figure is the mass the laboratory measured in the vial it received, and several retail sizes are filled from the same certified bulk lot. So a certificate can report a different mass from the vial you order. Purity belongs to the material and applies to every fill from that lot; the fill volume does not change it.
