The Claim
Short-term creatine supplementation (21 g/day for 5 days) does not enhance myofibrillar or sarcoplasmic protein synthesis in the legs of young, healthy men following acute resistance exercise, despite increasing total muscle creatine content by approximately 21%, indicating that the muscle hypertrophy effects of creatine may not be mediated by acute stimulation of post-exercise muscle protein synthesis.
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.
Taking a lot of creatine for 5 days doesn’t seem to boost muscle repair or growth right after a workout in young, healthy guys—even though it does increase creatine levels in their muscles. So, creatine might help muscles grow in other ways, not by speeding up protein building right after exercise.

What the research says
1 studyThe study found that taking creatine for 5 days didn’t boost muscle repair after a workout, even though it increased creatine levels in the muscle. This supports the idea that creatine helps muscles grow in other ways, not by speeding up protein building right after exercise.
