Okay, you don't need SARMs for progression. I'm sort of surprised you stalled off Stronglifts, but I don't know, maybe at 31 years old there was a little too much frequency, or maybe not enough accessory work, or who knows. Also possible there are technique issues if you want to post videos.
Look into Candito Linear:

First of all, I realize this is under beginner programs and you've been training a few years. Hear me out. At 178lbs, with a 200lb bench and 225lb squat, I think we can still get some linear progression out of you. That one is an upper/lower split that utilizes weekly progression. So the frequency is a little lower, but there's more opportunity for accessory work (pick whatever is appropriate based on where and why you miss your lifts...if you need help with that, describe where you miss lifts and/or post videos. No periodization, but you don't need that right now. If you try that, and really plateau again early, there's an intermediate 6 week program up there...that one's not bad either, but seriously start with the linear one first and run it as long as you can. I think you may surprise yourself. (Also I'm assuming you're male...if you're female, go straight to the 6 week...a 178lb woman might be able to linear progress a 225 squat, but you won't be able to linear progress a 200lb bench if you're a woman, at that point you'd need something a little fancier).
