With the EQ you need to run it for 12 to 14 weeks minimum. It's a long-ass sir. It takes a long time to reach peak concentrations in the body and I think 500 mg is the sweet spot.
RAD is the go if you want size. I would add some LGD in that case. If you want to do more of a recomp, then add some GW to it. You could also add some ostarine. I would go 20 mg on the RAD. That is perfect.
I wouldn't say Primo is necessarily for weak people but it is a weak steroid. If you use it solo you're not getting the androgens you need to grow and get stronger.
