about to be on TRT, looking to quell fears

starting TRT soon.

got glute shot and sore af (2 days ago). HCG subq (is that right abbreviation?)

here is my regiment, hopefully i start next monday:

1. 1ml T, split into 2/week dosages (so 0.5 ea)
2. 1ml HCG split into 2/week dosages
3. anastrozole 0.5 (1 cap)/week

18 gauge draw, 25 distribute

6 weeks from now, blood work.

questions:

1. they recommended IM for T and subQ for HCG - im scared of needles and the pain in my glute makes me think subQ for both would be better. thoughts? I dont want sore quad then i can foamroll to squat lol
2. They said 1ml = 210 test cyp. is that normal for first time (both test and HCG)
3. how about that stack, is that pretty normal?

its 225/mo + lab fees T_T
