Start my TRT Injections Now or Wait Two Months (Because of Uni?)

So I get my first vials of test cypionate and hcg at the end of this month.
I start my teaching practicum (teaching intermediate level kids for eight weeks) next month.
This is the second year into my degree and the practicum is decently important.
I was hoping to have started TRT the previous month but the endo delayed me.
Now I am debating starting TRT at the end of this month as planned or waiting until after the practicum.

I am also unsure on how long before I’ll notice the effects of the injections? The protocol I’m going to try is
50mg Test CYP every 3.5 days
HCG 250iu EOD.

Should I wait until after practicum as I may need to get dialed in and that could affect my teaching ability? Or should I start at the end of the month as the fatigue and brain fog from low T may already be impacting on my teaching ability.

I would start as soon as possible. Many notice improvement quickly. I did in two weeks.

If anything, fixing hypogonadism should improve cognitive function as the typically symptoms (brain fog, fatigue, irritability) will subside. That being said if the dose isn’t high enough you may not notice much of an improvement. 100mg/week works for many but some individuals (such as myself) will only get to around 4-500ng/DL on such a dose. Start TRT asap though.

As to how long to notice benefits from the injections, testosterone cypionate is a fairly medium-long ester, in about 3ish weeks blood levels should increase to a notable extend and improvements should start to become apparent. By week 8-10 the test will reach peak concentrations, from then on testosterone levels will remain stable.

What were your labs like prior to TRT?
