REFERRAL OFFER
Affiliate link active via referral link
Our referral link records attribution without a percentage discount. On October 29, 2026 the new ?ref=XVVXY route opened product pages and set the affiliate cookie; the former /ref/XVVXY/ route returned not found. Comparison prices include verified public BOGO pairs where eligible. PeptideBenchmark may earn commission and occasional free product; those are not shopper savings.
PeptideBenchmark has a disclosed affiliate relationship with Zeptix Labs. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.

Zeptix Labs lists single-vial research peptides, including the house codes GLP-1 S, GLP-2 T, and GLP-3 R. The public COA library publishes a certificate PDF for many listed strengths. The October 29, 2026 check uses current merchandise prices and verified buy-one-get-one pairs for eligible strengths. The referral link records attribution without an extra percentage discount. The vendor’s other codes and bulk offers are not combined with those prices.
Readers who want a short U.S. catalog with house GLP codes mapped on the pricing board and a public certificate library that includes laboratory-hosted Freedom reports.
GLP-1 S, GLP-2 T, and GLP-3 R are house codes for semaglutide, tirzepatide, and retatrutide. The BPC-157 and TB-500 blend was in stock at the October 29, 2026 check. The semaglutide listing at the larger strength links the smaller-strength certificate, so that file does not establish coverage for the larger vial. Some library cards share a document. Match the certificate to the actual strength and lot. Public BOGO pairs are compared separately from single vials; the referral link adds no percentage discount.

Checked September 24, 2026Public COA library with Freedom Diagnostics and Accumark Labs provider verification
The public COA library hosts certificate PDFs. Freedom Diagnostics reports and Accumark Labs AccuVerify pages resolve under the Zeptix Labs client. Freedom reports support identity, HPLC purity, and net content, with endotoxin and microbial results on some of those reports. Accumark pages support identity and HPLC purity. A strength-specific report is not treated as testing every other strength.
