can you use sarms between steroid cycles?

So I did 12 week steroid cycle and pct. I’m in between my cycles now and planning my next cycle which will be test prop and anadrol for 8 weeks.
Looking to conserve my gains as much as possible by using sarms in between the cycle.
Don’t see much information about recommendations for this but I’m assuming that I’m all clear to use ostarine mk2866 and maybe nutrobal mk677.
Would both of those work and what dose?
I’m 24 years old and I’m six foot 1 and 216 pounds
