First, welcome to the forum. Second, you need to find a new doc as yours does not know hormones at all. The half life of test is 5-7 days. He is dosing you on it's terminal life which is idiotic. None of the best doc's in the country would recommend this. It puts you on a hormonal roller coaster ride. Take a look at the graph below to give you a quick idea:

At a minimum you should be on weekly injections. Every 5 days is popular as is twice per week but we are obviously talking about more reasonable doses due to the frequency. I'd strongly suggest (if you can self inject) that you drop back to about 100 mgs every 5 days and retest some basic BW in about 4 weeks or so. What your doc has you on is simply not a healthy protocol.
I'm curious, are you on any form of estrogen control right now?
How is your hematocrit level?
Can you post up any current BW?
Regarding your question about pct it is not needed like 73 said above. Visit the AAS Q & A Forum and read the Successful First Cycle sticky thread at the top of the forum. It will explain all you need to know for a first cycle, including for those on TRT.
