Good
Sells retatrutide under the code name "LCA-R3" in eight vial sizes from 10mg to 60mg; lab reports from Kovera Labs (verified on the lab's site) and Freedom Diagnostics name the compound retatrutide. The site gives no legal entity, address or shipping origin, and ordering requires a free research account.
Worth knowing (not scored)
- No legal entity named on the site
- Retatrutide identity: product name 'LCA-R3' only; the Kovera Labs reports name the sample 'Retatrutide' with CAS 2381089-83-2 and LC-MS identity 'Retatrutide', and the Freedom Diagnostics 60mg report names the product 'Retatrutide 60mg'.
- Kovera Labs verification (koveralabs.com) returned matching records for all four Kovera reports (lot, purity, net content, retatrutide identity; order IDs prefixed 'LOS-'). Freedom Diagnostics site blocked automated access.
- Also sells an 'LCA-T2 / LCA-R3 BLEND' 60mg vial ($77; 48mg/12mg in the description, 40mg/20mg in the title), not listed as a retatrutide product row.
- Prices are public, but adding to cart requires creating a free 'research account' (21+ confirmation).
- Catalog also includes IGF-1 LR3 (out of stock), oxytocin (out of stock), kisspeptin and 'Lipo C with B12' (out of stock); no steroids, SARMs, HGH, HCG or testosterone found.
- No legal entity, street address or phone on the site. The Trustpilot company description calls it 'a California-based research supply company'; the site itself does not state where it ships from or confirm US-only shipping.
Points in its favor
- Eight retatrutide vial sizes from 10mg to 60mg at low per-mg prices
- Kovera Labs reports verified on the lab's own site
- Recent Freedom Diagnostics reports (September 2026) with multi-vial purity and endotoxin results
- Trustpilot 4.7 from 37 reviews
Points against
- No legal entity, address or phone disclosed
- Shipping policy gives no carrier, cost, delivery time or origin
- Card payment only by manual invoice; otherwise Zelle, Cash App or bank link
- All sales final with a 24-hour damage-claim window
- Account registration required before ordering
