For bloods during your cycle i would get something like
CBC (blood panel)
liver & Kidney function
E2 (sensitive estrogen) to check AI dosing
prolactic to see if you need caber with your deca dose.
prolactin probably isn't neccesary if there is an extra cost involved. On 400mg deca you should be fine just keep estrogen under control and probably won't need caber.
@flipcollar can probably advise you better on the blood tests within the USA. I think all of the above should be available as a 'deal' of some sort, excluding the prolactin, for around the $100 mark.
