Well, you need to maintain ample supply of Protein, to just maintain your current muscle mass, and increase your consumption if you want to build more.
And you need to keep your carbohydrates ample to supply you with the necessary glycohen for your activity level, if not, it will cannabilze muscle tissue. You dont want that.
So keeping carbs up spares muscle protein from being used as fuel.
You also need to keep up your intake of healthy fats.
Mainly, Omega 3.
Make sure your Test levels are at least steady by taking ZMA every night before bed.
So calculate your body weight, and calculate the time and rough energy expenditure to decide how much carbs you want to keep up.
It's ok to experiment.
But you're in a position where you're lifting, and performing another strenous exercise. You have to keep in mind the demands of both.
Im sure you're following the general rule of about 1 gram of protein for pound of body mass. To about 2 grams per pound, divided throughout meals throughout your day. This is to maintain, or help increase muscle mass.
WBA would be able to make you a sound nutrition program if you ask nicely.

Good luck.
