Peptide Giants publishes a public Lab Reports table listing 45 certificates. Its Lab column names Vanguard Laboratory on all 44 rows that carry one, each giving the batch code, the measured purity with its tolerance and the test date — for example CJC-1295 no-DAC 5mg + BPC-157 5mg, batch PG-6012, 98.91% ± 0.18%, tested 10 August 2026. Janoshik remains in use alongside it: 21 rows link out to certificates hosted on janoshik.com, each individually verifiable there with a unique key and QR code and carrying a Janoshik task number and a PG batch code. Neither set prints the analytical method.
