He asks because that is part of the protocol that is generally accepted on this site. Without bloodwork you dont know if you have recovered or if your estrogen is too high or too low.
So....bloodwork before cycle (especially first cycle) then bloodwork mid cycle (to adjust your AI) and bloodwork after pct (to evaluate recovery).
I'm guessing you don't use an AI? No hcg either right? Do you blast and cruise or do you cycle? Are you on trt yet?
We all need to know your stats. Age, weight, height, bfp. I could talk and ask questions of you for hours. Lol. Sorry......the "why do you ask" threw me a little. The beginner cycle sticky is a good place for you to start. Read there and you will find most your answers.
Your first cycle sounds like a MONSTER. No ai then either? How were your sides? What were your gains like? If you didn't have significant sides at that dose for a first cycle then I'd find a new source.
Anyway.....in case I don't hear from ya.....take care bro, good luck and God bless
