Creatine

[Journeyman]

i remember at my old gym there were brothers only a year apart in age and one of em took creatine while the other didnt...the one who did take it got bigger but the one who didnt always outdid his sibling in sparring cause he was simply quicker.

ofcourse skill level isnt taken into account but they were pretty even from what i had previously seen. and this was throughout a stretch of like 6 months or so...
