Creatine Monohydrate vs. HCL: Which Should You Choose?
Creatine monohydrate is the original and most-researched form — and for most people it's the sensible default. You'll see other forms marketed as upgrades: hydrochloride (HCL), buffered versions, and others, often promising better absorption or less water retention. The thing to know is that monohydrate remains the benchmark precisely because it has the longest track record and the most research behind it.
The alternative forms aren't necessarily bad, but they're usually more expensive and don't have the same depth of evidence. Unless you have a specific reason to try something else, plain monohydrate is the proven, economical choice — ideally a single-ingredient, micronized version for easier mixing. Don't let "advanced" marketing talk you out of the form that's actually best studied. More in creatine monohydrate basics.
