Higher intensity cardio, like running 3-4 miles at one time, will have an adverse effect on muscle hypertrophy. Best to do low intensity cardio for 30 mins 3 days a week. Keep the running for post cycle. It took me awhile to give up the cardio, but it worked.
Also, I don't think that you are getting enough cals at enough times during the day. You need to be eating 6 times and getting at least 4000 cals. 200g of protein at least. Try having a shake in the middle of the night when you get up to pee because of the 2 gallons of water you are taking.

Make a protein shake at night before you go to bed, then when you wake up in the middle of the night slam it down. Then, have a whey protein shake as soon as you wake up. Within 30 minutes of finishing your workout, you should have a protein shake with at least 40 grams of protein and about 75 grams of simple sugars. Then eat a regular meal with plenty of protein and complex carbohydrates within the next two hours after workout. You should also drink a slow acting protein shake(casein) before you go to bed. Eat meals every three hours during the day or substitute with protein shakes. In other words, eat even if you don't want to, but eat clean.
