Pinning and Blood Test Timeframe

I pinned last Friday 1/5 of test cyp 250mg, tren E 200mg, and EQ 200mg. I’ve been on the keto diet for 11 days now and haven’t lost a single pound so I would like to get blood work done to make sure everything is ok under the hood. There has been times before too where I have dieted hard for a month and saw no weight fluctuation. My workouts are on point and my macros are all calculated and everything so that shouldn’t be the problem (I’ve consulted with a dietitian)

How long should I wait to do the blood work so the pin last week won’t affect the numbers? I have also been taking arimidex throughout the last week because of nipple pains, should I stop taking that until the blood work?
