Medium confidenceUpdated 2 days agoMethodology →

Reta One Labs is a newer vendor with a limited community history but maintains a public per-batch COA library verified by an independent lab, placing them in the highest tier for purity testing. They offer credit card payments only, which limits payment security options. The vendor's catalog is relatively small with 17 listings, and community engagement is minimal with only a few Reddit mentions and no Trustpilot reviews. Pricing appears competitive based on available data. There are no known FDA warnings against them.

Pros & Cons

Pros

  • Public per-batch COA gallery at /test-results/ from Kovera Labs (independent compound testing CRO in Buffalo Grove, IL with HPLC/LC-MS purity + identity testing and verifiable COAs) — same community-independent tier as Janoshik / Finnrick / Vanguard / Chromate
  • Aggressive Retatrutide tiering — six single-vial sizes (RO-3R 10/20/30/40/50/60mg) covering the full dose-scaling range without committing to a 10-vial kit
  • Cold-chain shipping option exposed as an explicit checkout add-on — most peptide vendors handle this implicitly or not at all
  • Multi-tier Tirzepatide (RO-2T 10/30/60mg) and Semaglutide (RO-1S 10/20mg) sizing alongside the deep Retatrutide line
  • Hero blend lineup — BPC/TB, CJC/IPA, KLOW 80mg, GLOW 70mg — at competitive single-vial pricing
  • 60mg single-vial Retatrutide ($239) and 60mg single-vial Tirzepatide ($159) — uncommonly large sizes at this price tier
  • Customer coupon STACKEDHQ for 5% off at checkout

Cons

  • Several SKUs out of stock at last scrape (RO-2T 30mg, MOTS-C 10mg, Tesamorelin 10mg, GHK-Cu 50mg, BAC Water 3/10mL)
  • GHK-Cu topical serum + bacteriostatic water + cold-chain shipping listed alongside injectable peptides; researchers focused on a single delivery format may need to filter manually
