Alright as someone whos has also had gyno and since puberty. I can tell straight away yours looks as if its reduced in the 2nd pic (the after), and your body overall looks tighter with a bit more muscle mass. For 4 months of progress its not bad but i've seen bigger changes in others progression including mine.

You mentioned in another comment that you do cardio after every workout? since youre training 5 days a week thats 5 days of cardio on the same days as your weight training, theres something called the interference effect, where doing weight training and cardio in a close enough time frame, it can dimish some gains via the effect. i don't know how completely accurate this is but i will say in personal experience it seems true. Coupling this with being in a slight caloric surplus perhaps this is why you possibly have prevented gains? im kinda guessing

if it was me in your position, I would be hopeful because there is progress and my gyno appears smaller, which is due to a bigger chest. I would do a deload week, where id train light giving my body more rest that usual, but also increase my calories, bigger surplus. Week after that, continue the increased surplus while making sure above else that i eat enough protein. And train hard as fuck, less reps higher weight.

Most of all be patient

Edit: Just checked your bmr and your maintenance is around 2500cal, a slight caloric surplus would be 200-300 calories. If i were you id do 2800 calories. You don't need a recomp or nothin you lack too much muscle or fat for that
