Live (blocks automated checks) Transparency score 15/100* Checked Oct 15, 2026. Visit greatbasinbiosupply.com

Our findings in brief

In short: We could complete only 3 of our 6 checks on Great Basin Bio Supply, because its site blocks automated checks, so its 15/100 mostly reflects what we couldn't check, not what it hides.

We haven't lab-tested anything from Great Basin Bio Supply, so this covers public evidence only, not product quality. As of Oct 15, 2026:
