Probolic is okay, but too expensive. Up your mass is a rip off and not a very good product IMO.

Really you don't need a weight gainer if you eat right. Read the How to Bulk sticky if you haven't already.

The best weight gainer for the money that I've seen is the 10lb tub of Muscle Juice. Also, for protein you'll probably want to go with optimum nutrition's 100% whey. Or something similar. You can make your own blend at trueprotein.com...something similar to probolic and it will probably be cheaper.
