Reading a SS-31 certificate

Purity is measured by reverse-phase HPLC on a C18 column with detection at 214 nm — the trace shown under each batch above. The figure is the share of the signal in the SS-31 peak, and it is reported against the specification printed beside it.

Identity is confirmed separately by LC-MS, which checks the mass of what is in the vial against what is expected for SS-31. Purity without identity would say how clean the sample is, not what it is.

Net content is the measured quantity in the vial against its stated fill. Endotoxin is reported against its limit, sterility as growth or no growth, and heavy metals as a screen for arsenic, cadmium, lead, mercury.

Verify a batch yourself

Every certificate carries the lab’s report number and access code, both published above. Enter them on the lab’s verification page and the laboratory returns its own copy of the record. Vials ship unlabeled, so the batch number for your order is on your invoice.

FREQUENTLY ASKED

4 ITEMS
Does SS-31 come with a certificate of analysis?

Yes. 2 batches of SS-31 have a published certificate, covering the 10 mg fill (BATCH-234561) and the 50 mg fill (BATCH-772210). Every fill currently in the catalog is covered. SS-31 is sold wholesale in 10-vial kits from $64.00 per vial, with per-tier pricing on the SS-31 product page.

What purity is SS-31 tested to?

The published batches were tested by reverse-phase HPLC against a purity specification of more than 98%. They returned 99.346%–99.351%, reported at the precision the laboratory issued.

Who tests SS-31?

An independent third-party laboratory. The 2 published batches of SS-31 (BATCH-234561, 10 mg and BATCH-772210, 50 mg) were certified August 5, 2026, each tested for purity, identity by LC-MS, net content, endotoxin, sterility, and heavy metals, with the lab's report number on the certificate.

How do I verify a SS-31 certificate?

Enter the report number and access code printed on the certificate on the lab's verification page, linked from this page. Both are published here for batches BATCH-234561 and BATCH-772210. Vials ship unlabeled, so an order's batch number is on its invoice.
