The Claim
Creatine supplementation during resistance training in young men increases skeletal muscle mass and muscular cross-sectional area by approximately 10–15% over eight weeks, regardless of whether creatine monohydrate or hydrochloride is used.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In young men doing resistance training, taking creatine for eight weeks results in a 10–15% increase in skeletal muscle mass and muscle cross-sectional area, whether they take creatine monohydrate or creatine hydrochloride.
See the scientific wording
Creatine supplementation during resistance training in young men likely increases skeletal muscle mass and muscular cross-sectional area by approximately 10–15% over eight weeks, independent of whether creatine monohydrate or hydrochloride is used.
Creatine enters muscle cells and boosts energy reserves, allowing more intense and longer workouts. This extra energy lets muscles work harder, triggering growth signals. At the same time, creatine pulls water into muscle cells, swelling them, which tells the cells to build more protein and stop breaking it down. Together, these effects cause muscles to grow larger and stronger.
What the research says
1 studyWhen young men took creatine (either kind) while lifting weights for 8 weeks, they gained about 10–15% more muscle in their arms and thighs than those who didn’t take creatine — and neither kind of creatine was better than the other.
