how would you run nutrobal here?

I’m curious about how would you recommend I use mk677 nutrobal in this stack.
A friend recommended that I use gw501516 but I’m not sure if that would be the best option.
My goals are recomping.
I’m currently in my early 30s and this will be the second time I’ve used sarms. First time I use them I did lgd and I didn’t have much results at all doing 10 milligrams a day for four weeks.
