How to Read an SS-31 Certificate of Analysis
What KYIN Peptides' SS-31 certificate of analysis actually reports, and how to independently verify it.
What KYIN's SS-31 COA Reports
Every batch of KYIN's SS-31 is independently tested by Janoshik to 99.716% purity. The certificate reports an HPLC purity result and a mass spectrometry identity confirmation verifying the sample's molecular weight matches SS-31's expected amphipathic tetrapeptide sequence.
Why Identity Confirmation Matters for a Clinically Relevant Peptide
SS-31 (elamipretide) is one of the few compounds referenced on this site with a related FDA-approved drug (FORZINITY, for Barth syndrome), which means the exact sequence has real clinical significance rather than being purely a research curiosity. Confirming the sample's identity via mass spectrometry, not just its purity percentage, is the most reliable way to verify you have the correct amphipathic tetrapeptide sequence.
Elamipretide Branding and Search Confusion
Because SS-31's approved-drug name (elamipretide) and brand name (FORZINITY) both circulate online, searches for the compound sometimes surface pages describing the FDA-approved drug's clinical use rather than the research-grade peptide. A certificate of analysis is specific to the research compound KYIN sells, tested for laboratory use, and doesn't carry over any claims associated with the approved pharmaceutical.
How to Verify Independently
Given SS-31's clinical relevance, independently confirming a certificate is particularly worthwhile: search the batch number at janoshik.com/verify to cross-reference it against Janoshik's own records. See our general How to Read a Certificate of Analysis guide for the principles that apply to every compound in KYIN's catalogue.
SS-31 testing questions
What purity does KYIN Peptides' SS-31 meet?
KYIN Peptides' SS-31 is independently tested by Janoshik to 99.716% purity, with mass spectrometry identity confirmation — see the current batch's certificate of analysis on the product page.
Why does identity confirmation matter more for SS-31?
SS-31 (elamipretide) has a related FDA-approved drug (FORZINITY), giving its exact sequence real clinical significance. Mass spectrometry identity confirmation, not purity percentage alone, is the most reliable way to verify the correct sequence is present.
