Compare observed vial prices, price per mg, and current indexed COA records across vendors.
Indexed documents do not establish product quality. Missing means we have not indexed one. Index as of Aug 2026.
Some outbound vendor links are affiliate links. Commission status does not change the displayed prices, indexed COA fields, or certificate filters.
Observed market data
Document coverage, not product quality.
Observed PNC-27 listings span $34.99-$500 in total vial price, with a median of $15.80 per mg across 25 usable listings as of Aug 30, 2026. Compare PNC-27 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 has a current certificate on file for 10 of 21 tracked PNC-27 vendors, with 26 public documents. Vendors may have testing that we have not indexed.
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.

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.
