I am not a bodybuilder so perhaps not the best to take advise from. If the goal is purely aesthetic development by all means listen to everyone here. The initial post is approaching the issue as though which compounds to utilize will illicit the next level to bump you out of this plateau.
Personally, I am a huge fan of batching. I try to maintain a 6 min mile, 600 pound squat and 600 pound deadlift year round while maintaining flexibility and durability. First several years I could hold strength based goals but not cardiovascular or vice versa or I was a walking injury.
I alternate months of training now of speed work, stregnth work, durability, distance work, etc. Somehow truly focusing on one modality over another really helps generate parabolic curves in advancement. As long as I maintain my baseline training in the other areas I will maintain what I worked for or maybe have a 5% drop off.
ID honestly say stay on a TRT +20% dosage and try something remarkably contrarian to what you have always done. Change the training for 4-6 months, add in 3x weekly swims, intermittent fasting, mobility work, etc.
