I just wanted to discuss peak week as I’ve lately read a few posts around the sub-forums of this board. I’ve read some stuff in which manipulation of water and salt are discussed. My peak week was as simple as can be.
Here it was:
Sunday through Thursday: ketogenic diet with three depletion workouts for the upper body spread out through the week. No cardio.
Friday: Carb-up (with small amount of protein at every sitting) and supercompensation-pump workout for my lagging chest.
A LOT of water every day except show day.
Show day: small amount of protein and carbs in the morning. Then rest of day a shit ton of sugary carbs, some rice cakes, salt, and small amounts of water here and there. I went on stage SEVEN times in one day though. 
It doesn’t have to be complicated, and if you’re shredded already, I don’t think there’s much that can go wrong anyway.
