Dropping to a cruise

I’m currently taking 350mg/week of Test C (split EOD) and have been happy with the results. My test levels went up, as did much strength, endurance and measurements. But my E2 and Prolactin are rather high (468pmol/L & 1033mlU/L) although I have been side effect free (apart from some acne). I was previously advised on here and Telegram that if there were no problems to leave AI for now. I have about 4 weeks until I plan to drop to a cruise.

My question is when I drop my test down to a cruise dose will my E2 and prolactin drop as well or is there something I need to do to mitigate any problems. Prior to starting any AAS they were in normal ranges and i was about 14% BF (currently about 17% due to eating to build size and performance). Or will there be a period where they are totally out of whack with my dropping test levels?

Any advice greatly appreciated.
