sarms in between steroid cycles

I’m doing 12 weeks cycles of steroids using Deca and equipoise with testosterone. I’m going to be taking about 15 weeks in between the cycles and cruising and I would like to use sarms during that cruise where I will be doing 150 milligrams of testosterone only.
What are the best sarms that you recommend for holding onto gains? I’m currently 185 pounds and five foot six. Don’t want to lose any of my mass that I’ve worked hard for
