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 $6/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.

The index holds 81 public LL-37 certificates of analysis. We found certificates from some of the LL-37 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
1 evaluated certificates
1 graded · 0 not graded · 1 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

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.
