All I do is EQ, winny, and var... and I don't use test. And no, I don't feel like crap without test. But I do feel like like crap when I'm all bloated out from test. But ****, at least my dick is hard!
EQ and winny is in fact a dangerous combo. I have never had more injuries when I was on that combo and going heavy. Fortunately none of them were serious and I was able to bounce right back. My recommendation would be to not max out, and don't go to failure. If you can't get 8-10 reps then don't try it.
You will get great definition and vascularity. I put on 17lbs from my last EQ/winny cycle and kept just about all of it.
Winny is a collagen builder and makes the tendons larger, but affects the cross-linking integrity making them more brittle.
IMO winny though more dangerous than var, is a much better cutter than var.
