Stacked Score

/ 100Solid

Medium confidenceUpdated 6h agoMethodology →

Reta One Labs is a newer peptide vendor with a public per-batch COA library and independent third-party testing, placing them in a high trust category for purity testing. However, they have limited community presence and no significant Reddit or Trustpilot reviews, impacting their community reputation and customer service scores. They offer credit card payments but lack alternative methods, and their catalog is relatively small with only 17 listings. No FDA warnings have been noted, maintaining a clean regulatory record.

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
