What we found at Crush Research

Read 31 October 2026 on the vendor's own pages

The most detailed batch record we have read from a small vendor: three vials per lot, sterility and heavy metals on recent lots, a certificate that checks out at the lab, and the light batches left up for anyone to see. It stops at eight because there is no registered company name and only 30 reviews so far.

Score history and the caveats

A score only moves when the evidence does
  1. 31 Oct 20268/10 — first assessment (rubric v2): ILS Laboratories certificate confirmed with its access code (10.42mg on a 10mg label, three vials); 197-result batch table including light lots; card checkout; not awarded: identity (no registered entity), review-base (Trustpilot 4.4 / 30)
Purgo Labs: the caveat

Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.

Crush Research: the caveat

The site names 'Crush Research Supply Company' with a Canoga Park, California suite address and phone number, but no registered entity (LLC, Inc.), so identity is not awarded. Thirty Trustpilot reviews is below our 50-review floor. A July 2026 reviewer reports a Visa payment billed by an international merchant in Mexican pesos. The shop grid showed every product as out of stock with no price on our read, while the product pages showed prices and stock counts. Refunds and cancellations can carry a fee of up to 10%.
