Best and most drinkable gainer
Most weight gainer powders are overly thick, overly sweet or leave you bloated and feeling nasty for hours. I've used ISO-Mass since the days GNC used to stock it, and quite honestly there's not another gainer that can come anywhere close. I used to, on two shakes a day, be able to pack on 10-15 pounds in a month on this stuff. I've never had that kind of luck with other gainers. This one is a thinner consistency, mixes easily and goes down easily. Yes, it is expensive, but when you look at the breadth of ingredients in it, you'll understand why. Not only is the protein blend amazing, but it has several types creatine, NO precursors, beta alanine, omega 3s, vitamins and other goodies. It's supposed to be an all-in-one formula. This is the first tub I've purchased in about three years because I thought it was no longer being made. But it must have just been that GNC stopped carrying it. Either way, I'm happy to have found it.
