I like 'muscle & fitness' Australian edition, 'Australian musclemag' and 'ironman'. I would stay away from 'men's health' it is full of ads. The article to ads ratio in the magazines I have recommended is about 3:1, so it's really not that much.
One thing I've noticed though is that the whole issue of steroids is ignored, and you generally don't get bad reviews of supplements. Remember, these magazines are in the business of selling supplement ads, so if they mention that most supplements are crap and that what you really need is steroids they will lose advertising revenue.
