Compare observed vial prices, price per mg, and current indexed COA records across vendors.
Based on the certificates our crawler found; vendors may publish more than we index. Indexed documents do not establish product quality. Index as of Oct 2026.
Price-drop alert
Today’s lowest in-stock price is $2/mg. We check daily and email you once if it drops 10% or more. The alert ends after that, or after six months.
Some outbound vendor links are affiliate links. Commission status does not change the displayed prices, indexed COA fields, or certificate filters.
Observed market data
Based on the certificates our crawler found; vendors may publish more than we index.
Observed SS-31 listings span $20-$950 in total vial price, with a median of $5 per mg across 155 usable listings as of Oct 14, 2026. Compare SS-31 by vial size, total price, price per mg, stock signal, vendor coverage, and last-checked date. These market observations do not verify product quality or recommend a seller. Each vendor row shows its current COA record, including the reported purity, named lab, and printed test date.

The index holds 107 public SS-31 certificates of analysis. We found certificates from a few of the SS-31 vendors we track. Based on the certificates our crawler found; vendors may publish more than we index.
Choose “Highest COA purity” to sort vendors by the value printed on each current certificate. The number belongs to that document, lab, lot, and test date. It cannot establish product quality or safety, and values from different labs or methods are not directly comparable.

Certificate assessment
9 evaluated certificates
9 graded · 0 not graded · 3 in the A range.
Each result belongs to the named vendor’s certificate. Grades assess the document and its reported tests, not the vendor’s whole catalog or the safety of a product.
Automated checks can make mistakes. Open “Why this result?” for the reason and any review notice, and check the linked COA’s lot against your product. How grading works
9 evaluated records
Document grade
X2: The certificate's identity evidence (TM-1011 SS-31 ID by RT; TM-1011 SS-31 ID by Spectral) can't confirm the peptide on its own; that needs mass spectrometry or a side-by-side match to a reference standard.

A record appears on file after our pipeline identifies the document as a certificate of analysis and matches its printed compound to a catalog peptide. The record cannot prove authenticity, chain of custody, sterility, product safety, or suitability for use.
Lab, lot, date, compound, and purity fields are transcribed from the document and can contain extraction errors. “Older record” means the reported test date is more than 18 months old.
