Pros & Cons

Pros

  • Vanguard Lab UKAS ISO/IEC 17025:2017 accredited HPLC testing on every batch (peptide-specialized accredited lab, same tier as Chromate / Freedom / BioViridian) — ≥99% chromatographic purity guarantee
  • Public per-batch COA library — every batch's certificate accessible by direct URL at /coa/<slug>-<batch>.pdf (e.g. gip3-retatrutide-V260212-5.pdf), with the Vanguard batch number on the file
  • Veteran-owned, Stillwater Oklahoma based — adds operational accountability beyond a typical anonymous research-peptide vendor
  • Polished Next.js storefront with structured JSON-LD product data on every page (clean, fast, conversion-tuned)
  • Deep GIP3 (Retatrutide / triple-agonist GLP-1+GIP+glucagon) tiering at 10/15/20/30mg single vials — wider sizing flexibility than most peers' Retatrutide lines
  • Pre-mixed hero blends — BPC-157+TB-500 (5/5 + 10/10), CJC-1295+Ipamorelin (5/5), Tesamorelin+Ipamorelin (5/5 + 10/5), Glow (10+10+50 BPC/TB/GHK)
  • Free US shipping over $200, ships via UPS from cold storage
  • Customer code 'STACKED' applies 10% off at checkout

Cons

  • Per-batch COA PDFs are accessible by direct URL rather than indexed on a single COA library page
  • No Tirzepatide or Semaglutide in catalog — Retatrutide via GIP3 is the only GLP-class option
  • Credit/debit cards only (Visa/Mastercard/Amex) — no crypto, Zelle, or ACH for customers
  • US-only shipping
