So uhm, is this true? <_<

Mmmk, long story short, one of my friends (who IS Asian), and he lifts a LOT, told me that Asians builds muscles faster than most races/nationalities, is this true or not? I honestly can't tell. I started lifting recently (3 weeks ago), and I do notice that I've gotten a lot more buff. But then again, I'm sure so can most people.. right? <___< I mean, my arms are huge in comparison to what it was a month back, either that or I'm just imagining things. But maybe whatever my friend told me was true, who knows.
