I started EQ@400mg test@400mg for 6 weeks then bumped EQ up to 600mg. I'm @ week 9 and just started seeing my veins trying to wiggle out of my skin and pumps are torture. As for joints i've never felt anything abnormal.
Holyshit is right...it takes about 8-9 weeks to start seeing the effects of EQ. Last time I ran it I didn't like it that much. Dries you out a bit with a clean diet. EQ should also be ran at the higher dose of 600mg per week to get the full benefits. Just my opinion. Some guys will say running less is fine too.
