Verifying a FOXO4-DRI listing means matching the product name, the exact SKU, the nominal size of each vial and the number of vials in the pack, then opening the certificate of analysis (COA) that belongs to that SKU and a named batch. A product name by itself is not enough when more than one size is listed.
Listed SKUs, vial size and pack quantity
The FOXO4-DRI catalog record lists CAS number 2460055-10-9, molecular formula C228H388N86O64 and molecular weight 5358.1. Two public SKUs are shown: F42 at a nominal 2 mg per vial with 10 vials per pack, and F410 at a nominal 10 mg per vial with 10 vials per pack. The catalog covers publicly listed variants only and is not a claim that the list is exhaustive.
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 a single vial containing 100 mg. The pack total is label arithmetic, not an analytical measurement.
| SKU | Nominal size per vial | Vials per pack | Nominal pack sum (label arithmetic) |
|---|---|---|---|
| F42 | 2 mg | 10 | 20 mg |
| F410 | 10 mg | 10 | 100 mg |
Actual fill and peptide-content measurements belong to the particular batch report, not to the SKU table. If a quotation or other documentation uses a different packaging description, ask support to reconcile it before relying on the calculation.
Matching a batch COA to the SKU
A SKU identifies a listed product variant; a batch number identifies a batch record. Use both when locating a COA. Open the product page, select the SKU and read the matching certificate panel. Selecting a SKU updates the report without moving the viewing position.
Do not treat a report for F42 as evidence for F410, or the reverse, merely because both say FOXO4-DRI. An older published batch is not evidence of the batch that will be shipped next. Confirm the batch allocated to the order separately. If a public result is missing, that absence is not automatically a failed test, and it is not a passed test either. If a previously shared report link is no longer available, ask support for the current documentation rather than substituting a different batch.

Published F410 record: batch B9L1J1QLR100
The published COA for batch B9L1J1QLR100 applies only to SKU F410 (10 mg) and this batch. Certificate number QC-2026-KDY7F7A3BB lists the same laboratory and test date 2026-08-18. Summary lines record identity 5357.3 Da, purity 99.4 %, weight 11.45 mg and endotoxin <3 EU/mg.

Both records are published results for those batches only. Provider verification links were not independently fetched. They are not evidence of clinical suitability or of every batch.
HPLC purity and peptide content are separate line items on each certificate; they are not interchangeable. Gravimetric actual fill is a batch measurement against the nominal vial size, not a pack total. Bacterial endotoxin results are recorded as <3 EU/mg against a specification of NMT 10 EU/mg; that line does not establish sterility. Catalog molecular weight 5358.1 is a listed specification; the mass-spectrum results of 5357.3 Da are batch measurements against 5358.1 +/- 1.0 Da.
Verification sequence and checklist
Start by matching product name, SKU and batch number. Open the original report and compare its certificate number and test date with the summary. Then use the verification link for that report, following the COA verification sequence. A verification page may require an account with the report provider; seeing a link alone does not prove that a report is currently valid.
- Read the product and SKU from the FOXO4-DRI product page or the order documentation (F42 or F410).
- Check the per-vial size and unit (2 mg or 10 mg) and the number of vials per pack (10 on both listed SKUs).
- Set the number of packs required and confirm the packaging description matches the SKU table.
- Find the batch. If the allocated batch is not stated, ask support to confirm it.
- Open the batch page and check the certificate number, sample identity, test date and listed laboratory.
- Open the original report and compare the values and units with the summary.
- Follow the report-specific verification link. If the provider requests login or the record cannot be confirmed, resolve that with the provider or support before treating verification as complete.
- If details differ, send support the SKU, batch number and the specific difference. Do not substitute a report for a different size or batch. A screenshot can help comparison, but the original document and provider record are stronger verification evidence.
These two published records illustrate how F42 and F410 reports look on the stated test date. They do not describe unlisted SKUs, later batches or fields that were not recorded.
Frequently Asked Questions
Can the F42 COA be used as evidence for SKU F410?
No. A report for one FOXO4-DRI size should not be used as evidence for the other merely because both share the product name. Match SKU and batch together.
Does a published FOXO4-DRI report 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.
What does F410 packaging of 10 mg and 10 vials per pack mean?
It describes ten vials with a nominal size of 10 mg each, not a single vial containing 100 mg. The 100 mg pack total is label arithmetic, not an analytical measurement.
What if the COA verification provider requires a login?
Use the provider’s normal access process. Seeing a verification link alone does not prove that a report is currently valid, and a login-protected record is not independently confirmed by the product site.
What if no public COA is listed for the allocated batch?
Ask support for the exact SKU and batch. A missing public result is not automatically a failed test, and it is not a passed test either.
