EQ gives me horrible anxiety. I get all the benefits at 400mg with minimal to nonexistent sides but at 600mg i get this weird "shaking" in the back of my neck accompanied with an all around sense of feeling horrible. It's absurd but it is very real. I've gone as high as 800mg and after a while i got more used to it but every now and then I would have a full blown panic attack. Worst feeling ever. The higher the test dose the worse it is but even with low dose test it still hits hard. I'm just lucky like that..
