YES, its ok to do cardio on EQ. There is nothing wrong with that. If you were taking winny, then i would say cardio is up to you. Personally i dont like doing cardio on winny cause it weakens your tendonds/joints makes it easier to injure yourslef. So therefore winny is not the best for cardio. But with EQ, its fine. AND, when on cycle, cardio should be 45-min to 1hr. 4 times a week.

Im 5 1/2 weeks into a eq/sust cycle and do cardio twice a week. Every time cardio gets better, I'm liking it. Kinda bummed about lack of gains so far tho - 2 or 3 lbs, slight strength increase. I was planning on more from the sust by now. Oh well still got about 8 - 9 more weeks of gear to go.

Hey bud your g2g with EQ, it actually will help you since it produces more red blood cells so no worries on that, btw am currently on this stuff and it is slow but solid you won't notice a thing on it until the 5th week or more but no bloating or water retention! So keep doing your card as it will definitely help!
