Each sachet contained 30g whey protein powder and 5g creatine powder, administered twice a day. The first serving was consumed with breakfast and the second serving was consumed within 60 minutes of completing training or in the evening on non-training days. Participants also drank at least 2 litres of water per day

To evaluate the effect of combined whey protein and creatine supplement, as compared with whey protein supplement alone, on change in upper body strength from Baseline to Week 4.
Body strength will be evaluated using Repetition maximum (1-RM) and bench and leg press exercise testing. 1-RM in weight training is the maximum amount of weight one can lift in a single repetition for a given exercise
Time frame: Baseline, Week 2, 4, 8 and 12
To evaluate the effect of combined whey protein and creatine supplement, as compared with whey protein supplement alone, on changes in upper and lower body strength from Baseline through Week 12
Body strength will be evaluated using 1-RM and bench and leg press exercise testing
Time frame: Baseline, Week 2, 4, 8 and 12
To evaluate the effect of combined whey protein and creatine supplement, as compared with placebo, on changes in upper and lower body strength from Baseline through Week 12.
Body strength will be evaluated using 1-RM and bench and leg press exercise testing
Time frame: Baseline, Week 2, 4, 8 and 12
To compare changes in upper and lower body strength from Baseline through Week 12, between combined whey protein and creatine supplement, whey protein supplement alone, and placebo.
Body strength will be evaluated using 1-RM and bench and leg press exercise testing
Time frame: Baseline, Week 2, 4, 8 and 12
To compare changes in upper and lower body endurance from Baseline through Week 12, between combined whey protein and creatine supplement, whey protein supplement alone, and placebo.
Body endurance will be measured using bench press and leg press exercise testing
Time frame: Baseline, Week 2, 4, 8 and 12

Each sachet contained 30g of isocaloric carbohydrate powder and 5g of bulking agent powder, administered twice a day. The first serving was consumed with breakfast and the second serving was consumed within 60 minutes of completing training or in the evening on non-training days. Participants also drank at least 2 litres of water per day
To compare the changes in lean vs. fat body mass composition from Baseline to Week 12 between combined whey protein and creatine supplement, whey protein supplement alone, and placebo.
Body composition \[(fat-free mass and fat mass (grams and % body fat, bone mass)\] will be calculated using Dual X-Ray Absorptiometry (DXA)
Time frame: Baseline and Week 12
