Sample source: supplier-provided. The shop's supplier had this batch tested before it reached the shop, and the shop passed the certificate on. No vial bought from the shop was tested. If the lot on your vial reads RT30-061526, this is your batch's certificate. Supplier certificates are listed for information and don't count toward the Trust Score.How we weigh evidence →
