No one can tell you what injection frequency would suit you best.
Trial and error is the only way to find out.
Everyone is different.
Many men end up starting out injecting once weekly mind you twice-weekly is more the norm.
Downfall when injecting once weekly is there will be a big difference in peak--->trough (7 days) post-injection and blood levels will not be as stable throughout the week as T levels will be very high and in some cases sky-high (depending on dose of T) 8-12 hrs post-injection (peak)/during the first few days only to be followed by much lower levels come weeks end mind you many may still end up hitting a high-end/high trough if the weekly T dose is too high which would clearly mean they are being OVERMEDICATED!
The big swing in peak--->trough can easily have a negative impact on energy, mood, libido, erectile function and recovery due to the rollercoaster effect.
Some men prefer the big weekly swings.
Again depends on the individual.
Much more common now to start on twice-weekly and although there will still be a difference between peak--->trough it will not be as extreme as blood levels will be more stable throughout the week especially when injecting strictly sub-q which can have a positive impact on how one feels overall throughout the week.
Would not get too caught up on switching up your protocol (dose of T/injection frequency) as you need to retest your TT/FT to see where your levels truly sit.
Again highly doubtful you are hitting a ridiculously high TT 2500+ ng/dL 1 day before your true trough injecting 75 mg TC twice-weekly (150 mg/week).
As I stated previously even if one was hitting such at true peak it would be absurdly high as in no one using therapeutic doses of T would be hitting such let alone would never be needed for treating symptoms of hypogonadism!
What brand of TC are you using (big pharma/generic) or are you self treating using UGL gear?
