Notes for this study:
Creatine loading in amateur athletes improved their swimming performance on a single 50-m sprint (by 4.6% relative to placebo) but failed to improve the 100-m sprint. When all hormones were measured in a rested state, neither growth hormone nor cortisol had changed significantly, but testosterone had increased by at least 15%.
