Long Ester to Short

Hey guys, I was doing Test and Tren E had horrible sides and had to cut the tren out and wait it out…
I am currently taking 250 of Test… with 12.5 Arimidex e3d…
I am looking to salvage this and I am planning on ordering Test Prop with Mast Prop… so I can drop it quick this time incase of sides (mast) has anyone had bad sides with mast?

I am looking at running 100 of each eod… for 8-10 weeks.
When should I up the AI, should I start at .5 on week 2?
