If you are trying to put on mass especially if you are on gear 2600 cals for a 200lbs person is far too low. More like 3500-4000 cals would be sufficient, also 200g of protein is a little on the low side I would reccomend 300-350g protein per day. You might get some fairly decent gains from that but I would reccomend upping the protein and cals. Try supplementing with some protein shakes too, good luck to ya.
