Side-by-side
| Monohydrate | HCl | |
|---|---|---|
| Research | Extensive, decades | Limited |
| Typical dose | 3–5 g | Often 1–2 g (marketing claim) |
| Solubility | Moderate (micronized helps) | High |
| Bloating/GI | Rare at 3–5 g | Rare |
| Cost per effective dose | Low | Higher |
| Proven superior? | Gold standard | No |
The "smaller dose" claim
HCl is often marketed at much smaller doses because it's more soluble. But solubility in a glass isn't the same as how much creatine ends up stored in muscle, and monohydrate is already very well absorbed. There isn't good evidence that 1 to 2 g of HCl matches 3 to 5 g of monohydrate for muscle saturation.
Who might choose HCl?
If monohydrate genuinely upsets your stomach even at 3 g split into smaller doses, HCl is a reasonable alternative to try. For everyone else, monohydrate is the better value.
