I'm looking at going to California for training. I currenntly want to gain around 8 lbs, and am looking at being in California in 2 weeks. I can usually get to a PX at least every two weeks. I'm looking for something that doesn't take up a lot of room, no big jugs due to logistic reasons that is a protein supplement and preferably one that has high calories, low sugar. But heres the kicker I'm going to be in very hot weather, a lot. Oh and after reading that article about the lead in the Chinese sourced protein supplements scared me away from muscle milk I think permenantly... would prefer american made. If its a powder I could put 2 weeks worth in a quart sized container (canteen) that would work. Or bars, and I don't mind mildly expensive. The way I think though different brands have different things in them so a couple good ones to alternate would be nice. Any suggestions? Toss stuff out there that doesn't have a serious melting problem, or dense powders. I'll do a lot of research before I buy something. I plan on doing this until early december then slowing down because in Afghanistan I don't believe I will be able to get anything like this I don't bring with me. For everyone saying eat more and stuff... I'm goingn to be eating MREs 5 or 6 days a week, so this has the potential to help out.
