I bought a weight gainer because I needed a new jug of protein and I saw this ten pound jug with 55 grams of protein per serving for 50% off. I jumped for that and didn't realize it was a weight gainer until I got home. I have never really heard of weight gainers before and so I'm wondering if I wasted 25 bucks or not. Note: My goal is to gain weight, but now I'm worried that it'll all be fat. I'm awfully confused with my purchase right now.
