Score overview
How we score →Weighted composite across 8 criteria; the letter grade follows our published bands and integrity gate.
Key facts
Pros
- Best-in-class, independently verifiable testing for the industry: 96 per-batch COAs across 48 products from ILS Laboratories (ISO/IEC 17025-accredited, San Diego), with multi-vial (3-vial) HPLC plus identity, fentanyl, heavy-metals and endotoxin panels – three certificates personally opened (BPC-157 99.86%, Retatrutide 99.79% mean, KLOW 99.95% mean), and even the few sub-99% batches are published honestly
- Buyer-friendly commerce and clean tech: three payment rails (card via Stripe/NMI/Apple Pay, plus crypto and bank/Zelle) with card chargeback recourse, fast tracked US FedEx shipping (same/next-day dispatch, 3-5 day delivery, free over $200) with a damaged/incorrect replace-or-refund policy, transparent compare-at pricing, RUO + 21+ terms, and hardened security (valid HTTPS, HSTS+includeSubDomains, strict CSP, X-Frame DENY); Trustpilot ~4.4/5 with no scam or non-delivery complaints
Cons
- Newcomer with a thin public identity: domain created 2025-09-26 (founded Oct 2025, ~9 months old) with only modest review volume, and NO legal entity name (LLC/Inc) or physical street address published anywhere – contact is a single support email and a named founder ('Rory')
- Operational rough edges: several SKUs out of stock (BPC-157 10mg variant, TB-500), stale/contradictory site copy (About/FAQ still say 'we ship worldwide' while a banner and the shipping policy say international shipping is discontinued; damage-report window is 48h in the FAQ vs 7 days on the Refund page), no explicit lost-in-transit or seizure reship guarantee (risk passes on carrier handoff), and lab metadata that tags some records Freedom Diagnostics/BTLabs while the current PDFs all render as ILS (looks like consolidation/re-testing, not fraud)

When was this Crush Research review last updated?
This grade was last reviewed on 2026-07-04 under methodology v1.0.
A young but unusually testing-serious domestic vendor whose real, named-ISO-17025 (ILS Laboratories), per-batch, multi-vial COA program and card-plus-crypto-plus-bank payments outclass most of the field; personally verified independent purities sit at ~99.8-99.95% on the flagships. Held back mainly by newcomer status (domain <1 year, modest review volume), a thin public identity (no legal entity or physical address), stock gaps, and some stale/contradictory site copy.
