I was in Weights & Wimps Monthly about a year ago. I was a contest photo submission reject for their gain 5 lbs in 5 weeks competition. It's a good magazine.-lots of pics of guys sacks.
Another good one is Miniscule & Fatness. I'm on the cover this month posing with Gary Coleman and Verne Troyer(Mini Me). This magazine is not as hardcore but the sell a lot of different penis enlargement products in it so I buy it anyway.
Seriously I wouldn't buy one of those magazines cuz all they're good for is looking at contest photos-which can easily be done online for free. They aren't even magazines-just catalogs selling a bunch of snake oil that doesn't work. They also write articles that contradict themselves every other month just to keep you confused and frustrated from making no gains. This way out of desperation you may buy some of the shit they sell that doesn't work.
If I had the $$$ to burn on a subscription I'd get Maxim-normally I'd say Hustler's Barely Legal but I refuse to pay for porn when there's an unlimited free supply online.
