I disagree. I would not tell him you're on, not unless you have a damn good reason to. I would not have test levels tested if you just finished your cycle either. When did you finish your PCT? If you are going for blood test though I'd have him check your blood lipids (fasting so they can break down HDL, LDL, VLDL) and LFT (liver finction). There will be alot of other info that will come back with these tests also. Keep in mind, depending on when you finished your cylce and what you were taking these values may all be skewed from normal. Still, good info to know though. Good luck.
