I would always suggest doing the loading phase with any creatine product. Take 2 servings per day for the first 5 days (one immediately after your workout on training days). Thereafter, take 1 serving immediately after workouts on training days and just before you biggest meal on non-workout days. You may also want to re-load every 6-8 weeks, as some research suggests this can top up muscle creatine levels further with the accompanying benefits. For excellent information on creatine and all other supplements, I would strongly suggest that you read the articles - http:///view/v/article/a/25 & http:///view/v/article/a/10 in the Articles section.
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.
