Right now i'm taking creatine (creapure), and results are not that spectacular.
I'm not really seeing any water-retention or bloating. Which is kinda a shame, because now i don't know if it's working at all. I'm in a bulking phase now and have gained 2 kg, but i don't feel it's due to creatine, because there's some fat as well (+2 cm on waist). Calves have grown 0,5 cm and arms are +1 cm. But that's probably because i'm focussing better on this. Back, chest, leg strenght have actually gone down a bit (maybe that's because of exam stress).
Looking back it's not really worth it. I was stupid enough to buy a whole kg.
