creatine isn't for just bulking up at all - it's main purposes are to delay lactic acid buildup so you can train harder longer and it also aids in protein synthesis - bulking up is indirect so to speak. Cell volumizing due to water retention is a 'side effect'.. the newer types of creatine on the market these days do not do that as much. I know it's a relatively new thing, but studies show that most excess creatine intake is just 'pissed out' so to speak because your muscles can only store so much.
When i first tried creatine a few years back, i took cell-tech - gained almost 20 lbs after the first 2 weeks or so ... was able to work out longer, but the added water weight eventually wasn't worth it to me.. but i was able to stand it because i was as skinny as a rail before hand. I just tried it again recently - i forget which brand.. but water weight wasn't as big of a problem.. i added more glutamine at night , ala, arginine and protein to the mix -- wow. take it right and it's a killer mix
