Well I gave my friend something called creatine matrix back in february , by 'olimp' which is a combo of different creatines, wanted rid of it,as it involved taking a dose at night and it made me want to piss all night. But anyway, he credits this with startng off his transformation,he got really serious in his training and has gone from strength to strength.The creatine gave him enough extra energy to see the gym is a whole new light whereas before he was plateauing. Creatine isn't a miracle supplement, but what it does do, is give me a bit of extra energy and it does have the added benefit of adding on some size to your frame,but remember that unless you train hard and put muscle on , that size will go if you stop taking creatine as it's simply water in the muscles.
Creatine is also extremely cheap, you don't need to bother with a designer one really, although this matrix by olimp has worked wonders for my friend, but in general designer ones are just about making supplement companys extra money because again creatine is not only proven to work in studies but it's very cheap. Just get some creatine monohydrate to start off with, you don't need to cycle off it, only look at other types of creatines if your stomach has trouble tolerating monohydrate,my friend is one of those people.He used monohydrate at the suggested doses , did what was in the instructions, and he got the shyts so bad at work he had to miss a meeting apparently. But the vast majority of people can tolerate mono just fine.
Also last thing, stay away from krealkyln , a designer creatine which is supposedly 'easy on the stomach', not only is it more expensive than mono ,but I know two people who had to stop taking it when they got some weird kidney infection .
I personally use animal pump which has 3 gs of creatine in it, and I also take 2 g's of universal creatine mono extra later in the day, because Iam a big boy and train six days a week before work.
