Hey brother, there is no exat formula for mass gains that will work for everyone. There are a lot of factors involved. For instance, some guys will have an easier time handling carbs than others. For 1 guy, 400 carbs is fine while the next guy gets fat. So start out with about 1-1.5g of protien per lb of body weight, then about .5g fat. Then add carbs as you go and watch your response. So we don't know what you can handle until we see your response. What I do is start carbs around maybe 200g and then adjust each week based off of progress pics. Then once you figure out how many carbs to eat, see if you can push it a little further. Keep cardio low but add it in if needed
