Cons
- Newer vendor - operating footprint and long-term community history are thinner than top established shops
- Uses coded GLP names (EZP-1P / EZP-2P / EZP-3P / EZP-CG), so researchers need Stacked's mapping layer to compare cleanly
- Some products are tablets, diluent, shipping upgrades, or non-catalog compounds; those are intentionally excluded from Stacked's vial-focused listings
- Cookie window is not surfaced in the affiliate dashboard; pending direct confirmation
