Importance of Sleep for Muscle Protein Synthesis

I am hitting my macros and training hard, but I am only getting about five or six hours of sleep a night because of my work schedule in Philadelphia. I am wondering how much this is actually hurting my muscle growth. I know sleep is when you recover but is it a dealbreaker?

I have been reading about muscle protein synthesis and how it is affected by sleep deprivation. It sounds like I might be leaving a lot of gains on the table. I am trying to figure out if I should prioritize sleep over an extra meal or an extra session in the gym.

How much sleep do you guys get during a bulk? Have you noticed a big difference in your strength or recovery when you managed to get a full eight hours? I am really struggling to find a balance and I want to know if I need to make some serious changes to my lifestyle.
