You CAN of course but I would suggest caution. Many doctors want to draw labs relatively quickly after initiating TRT to see where the initial script has you sitting. I think Drs are just as worried about putting you over the top, and thus potentially making them liable were you to encounter a health issue, as they are about the dose being too low.
I had this happen when I attempted to work with a local endo. I was on 200mg/week FOR YEARS, with a script that I presented at the appointment and he still wanted me to start at 200mg Once every THREE WEEKS, so <70mg/wk. I very quickly found a new provider.
Anyways if you add in your UG and the Dr. tests you and you are a little high, and a 200mg dose timed poorly/absorbed/metabolized funny MAY have you above the top end of normal or even whatever number your Dr. wants to see. The last thing you want is to have him reduce the script further.
Now a clever fella could simply reverse this scenario if looking to increase your script.....................just saying lol.
