I keep things consistent.
I don't like to mess around with complicated cycles or food plans. They can really fuck around with your weight. So if you add anadrol and suddenly gain 10lbs of water that could put me over my weight class. If I ate a shit load of carbs a few days out my gut may be bigger which will impact my performance on the squat and deadlift.
Honestly if I were you, you look like you have been training a while, shoot 1000-1500mg of testosterone per week for as long as you can.
If you have anadrol and tren use it. I would just consider using it at the start and hitting up the meet with ONLY testosterone in your system so you know your weight. But then again your fairly new so just train hard and juice hard and see what you do.
