I've has USN muscle fuel anabolic a couple of times now after switching from the hyperbolic mass. I much prefer this shake because it makes me less bloated and gives me the same amount of protein as opposed to hyperbolic. I find that it's much easier to have a 2/3 of these without feeling too bloated or sick, whereas with hyperbolic mass I found myself not wanting to eat food .
I use it mid-morning between breakfast and lunch as a snack, and then lost workout or as a mid afternoon snack if I can't get to the gym, I find that it digests really easily and I can eat all my other meals throughout the day as well so overall it's a fantastic shake and it puts size on well.
High CK levels are common in bodybuilders and athletes for two reasons: 1) we use creatine and 2) we train hard. Both are known to increase CK. The best thing to do is to take a week off training and creatine before your next liver enzyme test and you may find that your CK returns to normal. If not take a month of creatine (to bring levels back to baseline) and a week off training before the next test. If CK is still high, then you may have a legitimate liver problem, which you need to discuss with your doctor (as I'm not qualified to diagnose disease).
