Step 1:
build yourself a fun cycle, preferrably short ester (so it clears your system quick)
example: Test e/ test prop @ 300 mg/week
sprinkle in some oral, nothing with heavy aromatisation (no gyno for your doctor to see)
Step 2:
run this for a while, look as your nuts shrivel up like a welting flower.
as soon as you reach anywhere between 1/2 to 1/3rd of original size,
around 3-5 months in, commence with
Step 3:
drop EVERYTHING
Step 4:
wait for the test to clear your system, (this is where using prop is better- it clears faster) you can pull bloods at an independent lab to gauge where you are, just make sure you dont go to a doctor for that bloodwork (INDEPENDENT lab)
Step 5:
once test is low enough ( sub 100 is the goal, the lower the better)
get your appointment with your doctor set up
If you know that they take blood at the doctors office, take enclomiphene or clomid ~24h beforehand, to raise FSH & LH, Lift heavy, or do excessive cardio, starve yourself, then commence to
Step 6:
Go to the doctor with your low T, seemingly normal LH and FSH, get your blood drawn, (remember, dont look too jacked on the day of your doctors visit

or else... )
Step 7:
have your concerned doctor tell you that you have low T and qualify for TRT, bonus points if you complained about low libido, lethargy and other stuff in the months leading up to the final appointment.
OR
you get lucky and get a doctor who just pulls test, nothing else.
Tldr:
You need
generous dose test prop, 1y x1.2g/month, aka 300mg/wk
1 or 2 bottles of non- aromatizing/non estrogenic orals
a tiny bit of enclomiphene (or clomid, both do the job well + its cheaper)
5 months of Androgen driven goodness and fun,
drop everything
wait for it to clear
take clomid+starve yourself+do excessive cardio/lift real heavy before you get your test measured
enjoy your Trt
