i'm about to get my first bw done since starting trt. i've been advised to schedule bloodwork at least one day after my normal injection, but not to taken the injection. i guess the logic here is to see what test serum and free test are after depletion from trt. somehow this doesn't make sense to me.

what are the trade-offs and recommendations for BW timing vis a vis trt injection timing?

interestingly, the same logic is applied to hcg (wait until after normal dose 'wears off'), but not AI. any additional thoughts here?
