Wrong section. Move to Testosterone Replacement
You don’t need HCG unless you care about fertility and preventing atrophy. Recommend getting Test dialed in before including HCG, then only at minimal effective dose, which is dependent on your goal.
200/wk is high, recommend starting at maybe 140-150/wk to see how you feel. If doing fine and no estrogen issues, bump to 200mg if you want to. More == better for many (myself included).
Splitting dose to 2x per week is ideal for most. Low SHBG guys may need to inject more frequently. I have super low SHBG so i was recommended daily injections, but i feel fine at 3x/wk too.
You can inject SubQ or IM. Some have preferences for one over another; I like SubQ.
Try not to touch AI. This is why i recommended starting lower than 200 negate because 200 causes too much E for some. 140-150/wk most never need AI to control estrogen. Dialing in E is troublesome… figure out 1 compound at a time.
Also great information
