I'm good now, I've been training like a maniac, and I see results. I'm back to 87kg's, but also I'm more leaner now, so I'm really satisfied. I used weight gainer (one box, 38 servings, 400Kcal with around 40g of protein per serving) and it helped me, now I'm using Caseine and whey protein, along with Creatine. I'm also thinking about adding Beta-alanine, but I'm not sure yet.
