17yr old on test, looking for advice on the next step

Id like a little advice on what i should do. Im 17 and 5’7 and have been on test since early September. Let me also say that going on test is the best decision ive ever made for overall mental and physical health. Please do not come at me saying im too young as it is monitored by my doctor and i have a coach. (Backstory- lifted for 4 years, diet, sleep, and exercises all optimized) Got my bloodwork done back in august and i had insanely low natural testosterone for my age even though i exercised, slept, and ate right. Since i couldn’t get prescribed trt by my doctor i decided to hop on 200 per week and notified him that i would be doing it. I ran 200 until i got bloods in December. All markers were perfect with no sides so i decided to bump up to 350 a week and decided i would do a bodybuilding show. I was on 350 till February and then i went up to 400 because this time of the year i deal with a lot of stress from just being involved in activities. Ive been on 400 ever since with no other compounds ever added. I have never had any side effects from test and have never used any other compounds like an ai or peptides (I have always pinned eod so levels don’t fluctuate) Since i started test i went from 135 lbs at 18% bf to 158 lbs at 10% bf. My show is may 30th and i dont plan on changing my dosage as there is no side effects and bloodwork that i got a week ago is still good. Pretty much i was wondering what do you guys think my next step should be. Im contemplating after my show pct-ing to see what my natural level could come back to and then hoping back on with other compounds also added. I love bodybuilding, dieting, and training, so i might pursue a future in it. If you have any questions please ask or just give me some advice on what my next steps should be.
