Prohormone Protocol?

I got some epistane from a buddy of mine for free, I don’t know much about prohormones, only use gear. Is it worth taking it? I don’t like orals from the fact that it can cause liver toxicity, but I heard It’s somewhat safe, like I said I don’t know much about prohormones.

What’s the protocol for it? and liver support and on cycle substances to stack with it? I plan on taking my HCG and anastrozole with it if I use it, anyone have experience with pro hormones?
