* Keep an anti-e such as exemestane on hand. Always.
* Liver protection. Get it. Synthergine is the best you can find. (No, I'm not affiliated with them. Wish I was, I'd really stock up.)
* Up your protein to 2gm/lb of bodyweight. Adjust as you gain. Get plenty of healthy fats too. Nuts, seeds and oils are your friends.
* Eat as much clean food as possible. People usually bloat because their diets are sloppy.
* Food means FOOD. Every 2.5 hrs or so. Superior to shakes. Shakes are great as a compliment to food, but always have food unless you absolutely can't then do a shake.
* You want to grow. Then train like it. Use an off season 3 (maybe 4) day split. You're not prepping - no reason to train 5-6 days a week. Drugs or not.
Chest/abs
Legs/calves
Back/abs
Maybe an arm only day if they lag.
No delt day? Many don't do any direct delt work early off season as the hard, heavy work on the chest and back hit delts nicely. Do traps on back day as well. Want to do a couple sets of shoulder presses and lateral DB work every other week on that arm day, fine. Just don't throw an hour of delts on top of the other work, no need.
* Do cardio. 3x a week for 20 minutes is fine. THis will help to keep your appetite up and use your food. Orals make your appetite dry up sometimes. This will help keep any fat at bay as well.
* Sleep. As obvious as it is, most people (yours truly included) miss this one. I know life gets in the way, but try to sleep as much as possible.
Good luck, keep us posted.
