Why Creatine Nitrate is tier 2

A dose-ranging safety/efficacy trial found comparable safety markers and performance outcomes to monohydrate, but the evidence base is much smaller and mostly industry-affiliated.

Why Creatine HCl (Hydrochloride) is tier 2

Marketed on higher-solubility claims, but the only real head-to-head human RCT (5g/day, 8wk, elite team-sport athletes) found similar effects on strength/jump/body composition to monohydrate -- no demonstrated superiority.
