23 is really not right as muscle damage is cumulative and we are taking decades.
Suggest #29 0.5ml 1/2" insulin syringes, SC/SQ or IM if you have too. Slow to load, injection time is OK.
Self inject 50mg T twice a week
0.5 mg anastrozole at time of injections [- dose dependent on T dose]
250iu hCG SC/SQ EOD to preserve testes and fertility
250mg T cyp/eth per week is not the way to start.
Oral body temps can be used to eval and adjust thyroid med dosing.
Please read the thyroid basics sticky.
