Creatine HCl

Alternative creatine form marketed for higher solubility; efficacy equivalent to monohydrate per gram active creatine.

Muscle GrowthAthletic Performance

Overview

Hydrochloride salt of creatine; more soluble than monohydrate but not more effective per dose.

Natural sources
  • Synthesized
Common forms
  • Creatine HCl

Mechanism of action

Same as monohydrate — replenishes ATP via phosphocreatine.

Pathways
  • · ATP regeneration
