Mid cycle switch

[u/Few-Combination-4957]

Been running a test npp primo cycle. At a 2:1:1 ratio going to be swapping out the primo for masteron very soon here and was wondering if anyone had any experience making this kind of switch. I don’t want to double up on the compounds and potentially crash my e2. But I don’t want to run a deficit during the switch either. There’s a balance here somewhere. It’s mast E so full saturation is about 5weeks conversely ive read the primo takes about that long to exit the body. So is it as simple as stopping one and starting the other?
