If you listened to Danny Roddy and Georgi you may have heard the talking about myostatin a how mutations in the genome can lead to lower myostatin production and induce hypertrophy-Myostatin - Wikipedia
The below study shows creatine in the regular dosing routine of 30g loading and 5g thereafter can lower myostatin ,it may explain creatine’s effect on muscle growth combined with resistance training.
Effects of oral creatine and resistance training on serum myostatin and GASP-1 - ScienceDirect
"Myostatin is a catabolic regulator of skeletal muscle mass. The purpose of this study was to determine the effect of resistance training for 8 weeks in conjunction with creatine supplementation on muscle strength, lean body mass, and serum levels of myostatin and growth and differentiation factor-associated serum protein-1 (GASP-1). In a double-blinded design 27 healthy male subjects (23.42 ± 2.2 years) were assigned to control (CON), resistance training + placebo (RT + PL) and resistance training + creatine supplementation (RT + CR) groups. The protocol consisted of 3 days per week of training for 8 weeks, each session including three sets of 8–10 repetitions at 60–70% of 1 RM for whole-body exercise. Blood sampling, muscular strength testing and body composition analysis (full body DEXA) were performed at 0, 4th and 8th weeks. Myostatin and GASP-1 was measured. Resistance training caused significant decrease in serum levels of myostatin and increase in that of GASP-1. Creatine supplementation in conjunction with resistance training lead to greater decreases in serum myostatin (p < 0.05), but had not additional effect on GASP-1 (p > 0.05). The effects of resistance training on serum levels of myostatin and GASP-1, may explain the increased muscle mass that is amplified by creatine supplementation".
