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.

This was a great read in that "other" publication that came out this month... looks like I am going to have to up the creatine

what other publication?

Well, I don't know the rules regarding referencing the magazine, but it was MD. I know there is a huge dicey past and bitter relationship between Dave/John and Steve, they always talk about it on their HMR show; I just didn't want to specifically mention MD in their forum - but they had this same exact expanded research article in this month's issue.

When I get off my lazy a$$, will have to add the above when I update my creatine report. Creatine increases IGF-1 MnRA also.

what dose? the standard 5g?
