Wood, K. K., Zabik, R. M., Dawson, M. L., & Frye, P. A. (1998). The effects of creatine monohydrate supplementation on strength, lean body mass, and circumferences in male weightlifters. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 1542.

Males (N = 44) who had been weight training for at least six months were divided into creatine supplementation, placebo supplementation, and control (no supplementation) groups. After six weeks there were no significant differences between the groups for 1 RM bench press, chest circumference, abdominal circumference, right upper-arm circumference, right proximal thigh, or lean body mass.

Implication. Creatine supplementation did not affect strength or body proportions after six weeks of ingestion and weight training.
