Each status is quoted from its source. A shop with no working website may still sell through messaging apps, which is a reason for more caution, not less.

Before you order 5-Amino-1MQ
- Look at the shop's grade for 5-Amino-1MQ, not its average. Retalux has the most 5-Amino-1MQ tests (3); a shop with one or two tests has not shown it is consistent.
- 100% of these vials were bought and sent in by customers; the rest were sent by Finnrick or by the shop itself. Results from vials a shop chose to send are the weakest evidence.
- 2 labs tested them, mostly Krause Analytical and BTLabs. Ask for the certificate for your batch and check it on the lab's own site.
- Run the vendor checklist before paying, and read how the grades work.
