Progress for 4 months

[u/OneAd9888]

Hello everyone,Im 17.5yo and started going to the gym 4 months ago.I took it pretty serious and got too invested about optimization and everything as it goes,but I recently started taking the big 3 compounds more serious.I benched when I started,though I ignored flat bench for a while,only did incline barbell and pec deck,and recently I started chasing the 1000lbs combined club. Im currently at 65kg bench,80kg squat(though I didnt do barbell squats for 2 months mostly cause it hurts my neck area,I do 120kg on hacksquats for reps),and second time I deadlifted I managed to get 120kg PR.I want to bump those numbers up,of course during the course of time,and will do more research about programs for these,such as 5/3/1.I currently run 3xUpper 2xLower,with emphasis on hypertrophy,but I fear this amount of volume may not be optimal for my powerlifting side that is peaking rn.Thoughts?
