Verifying DSIP means matching the product name, the listed SKU, and the batch certificate of analysis for that SKU. The DSIP product page lists CAS number 62568-57-4, molecular formula C35H48N10O15, and molecular weight 848.8 as catalog specifications. Those fields identify the listed compound. They are not batch analytical results.
Listed SKUs, vial size, and pack quantity
Three public SKU codes are listed. Each row has its own nominal size per vial and vials-per-pack count:
| SKU code | Nominal size per vial | Vials per pack |
|---|---|---|
| DS5 | 5 mg | 10 |
| DS10 | 10 mg | 10 |
| DS15 | 15 mg | 15 |
Those figures are nominal catalog facts on the DSIP product page. The listing’s SKU scope is public listed variants only, at most 40, and is not a claim that the list is exhaustive.
Editorial guidance on per-vial size versus pack quantity is to read per-vial size, vials per pack, and pack price as three separate fields. A description such as 10 mg × 10 vials means ten vials with a nominal size of 10 mg each; it is not one vial of 100 mg. On that reading, DS5 is 5 mg per vial in a 10-vial pack, DS10 is 10 mg per vial in a 10-vial pack, and DS15 is 15 mg per vial in a 15-vial pack. Any milligram total obtained by multiplying those fields is label arithmetic, not an analytical measurement. Actual fill and peptide content belong to the particular batch report.
How to locate and check a DSIP COA
A SKU identifies a listed product variant. A batch number identifies a batch record. Finding a COA therefore requires both: the product name alone is not enough when several sizes or batches exist. Open the product page, select the SKU, and read the matching certificate panel. Compare product, SKU, batch, and certificate number.
Do not use a DS5 report as evidence for DS10 or DS15 merely because all three are named DSIP. An older published batch is not evidence of the batch that will be shipped next. A missing public result is not a failed test and is not a passed test. Ask support for the exact SKU and batch when a public record is missing.
Verification guidance describes this sequence: read product and SKU from the product page or order documentation; find the batch record, asking support to confirm it if the allocated batch is not stated; check certificate number, sample identity, test date, and listed laboratory; compare values and units with the original report; then follow the report-specific verification link. A verification page may require an account with the report provider. Seeing a link alone does not prove that a report is currently valid. Provider verification links on the batch pages below were not independently fetched.
If SKU, size, or values differ, do not substitute another size or product. Send support the SKU, batch number, and the specific difference.
Recorded results for three published batches
Each COA below applies only to the named batch and SKU. None of these records is evidence of every DSIP batch, and none is evidence of clinical suitability.

On these three records, gravimetric actual fill is 5.67 mg against a 5 mg specification, 11.67 mg against 10 mg, and 16.32 mg against 15 mg. Those values apply only to the named batches. They are not a fill promise for other lots.
Checklist before you rely on a DSIP label or COA
- Match the product name DSIP and the exact SKU (DS5, DS10, or DS15).
- Read per-vial size and unit separately from vials per pack.
- Set pack count as its own field; do not treat pack arithmetic as a measured total.
- Match batch number and certificate number to that SKU.
- Compare each COA line using the same analyte, method, units, qualifiers, and determination shown on the record.
- If a verification link cannot be confirmed, or if any identifier disagrees, do not substitute a different SKU or batch.
Unknown results are not zeros, passes, or evidence of absence. Bacterial endotoxin figures here are LAL (gel-clot) results against NMT 10 EU/mg; they are not a sterility determination. These sources do not record storage temperature, shipping conditions, or legal conclusions.
Frequently Asked Questions
Does a published DSIP COA mean every order receives that batch?
No. Confirm the batch allocated to the order separately. An older published batch is not evidence of the batch that will be shipped next.
Can a DS5 COA be used as evidence for DS10 or DS15?
No. A report for one listed size should not be used as evidence for another size merely because both are named DSIP.
What if a public DSIP COA is missing for a SKU or batch?
A missing public result is not automatically a failed test, and it is not a passed test either. Ask support for the exact SKU and batch.
Which identifiers should match before relying on a DSIP COA?
Match product name, SKU, batch number, and certificate number, then check sample identity, test date, and listed laboratory on the batch record.
