If cruising to give yourself a break for health purposes I would not add var, it is hard on lipids which kind of defeats the purpose of a cruise. Adding other steroids to a cruise, at a decent dose, creates a cycle. I would look into something like iconic b-AET or Suppress-C. Perfect for cutting and will not defeat the purpose of the cruise.
You could also run a natty product like x-gels, follidrone, anabolic effect, vector.
I personally would feel like garbage adding a non-aromatizing steroid to trt test while using an AI and a serm. If you are trying to reduce gyno I think reducing your external hormone additions is the best choice. Fewer variables while addressing your primary goal, gyno reduction. Even non-aromatizing compounds can aggravate gyno through non-direct roundabout kinda ways.
