EQ (if you're taking a prohormone to EQ) can make people break out bad. I've read about it a lot before.
I'm prone and formestane didn't effect me negatively. Epistane (havoc) completely cleared me up! Was interesting..had no acne at all while on it until pct.
Accutane might be the only solution if it doesn't slow down, in combination with antibacterial soap, etc. Don't let it get too bad...see a dermatolgist before you end up with scaring. It's easy to let it go especially if it's mostly just on the back.
btw, Toronto's my home too.. or was my home for 10 years before I came to nyc for my job. I was just back there this weekend, beautiful weather, got a nice tan boating out on the lake
