EZ Peptides is a newer vendor with a strong foundation in purity testing, utilizing Janoshik Analytical for community-independent COAs and maintaining a public COA library. They offer fast shipping options and multiple payment methods, including card and crypto. However, their community reputation and customer service scores are limited due to a lack of Reddit and Trustpilot presence. Their catalog is moderately deep with 57 listings, and they maintain a clean FDA record.

Pros & Cons

Pros

  • Public COA library plus per-product Janoshik / verify.janoshik.com links on active product pages
  • Deep GLP-class coverage across Semaglutide, Tirzepatide, Retatrutide, Cagrilintide, and Survodutide
  • Strong kit pricing on Tirzepatide and Retatrutide - 10-vial kits materially lower the per-mg floor versus single vials
  • Broad standard peptide coverage including BPC-157, KPV, GHK-Cu, CJC-1295 No DAC, Ipamorelin, Tesamorelin, MOTS-C, DSIP, Semax, Selank, PT-141, and Melanotan I/II
  • Stacked visitor discount gives researchers 10% off through the partner link and checkout offer
  • US-only fulfillment with published 0-2 business day processing, tracking, and free standard shipping over $200

Cons

  • Newer vendor - operating footprint and long-term community history are thinner than top established shops
  • Uses coded GLP names (EZP-1P / EZP-2P / EZP-3P / EZP-CG), so researchers need Stacked's mapping layer to compare cleanly
  • Some products are tablets, diluent, shipping upgrades, or non-catalog compounds; those are intentionally excluded from Stacked's vial-focused listings
  • Cookie window is not surfaced in the affiliate dashboard; pending direct confirmation
