Creatinol-O-Phosphate is a synthetic compound related to creatine. Developers intended it as an ergogenic aid. Only a few small human trials have looked at its impact on exercise performance and recovery.
People take it by mouth, usually as capsules or powder. Some pre-workout and sports nutrition formulas include it. But the evidence is thin. Solid clinical data on its effectiveness and safety are missing. Compared to standard creatine monohydrate, far less is known about this compound.
Quality and purity differ between brands because supplements are not tightly regulated.
