Creatine might give you more size than Var. You're in your first week, how do you know what will happen from the 5th week on?? Now you have good results, you have your natty test + var doing the job. but soon you'll have test levels like a Little bish. var alone will be no longer as efective. and gains will probably stop.
I tell you this from experience. I did a Hdrol only cycle, and from the 5th week on, I started feeling weak with no libido. shure I saw some results, but they went away as soon as I ended my PCT.
