Addition to
ursuLenes Mag post.
Muscle&Fitness > only does Dom and Strength. (it alone will not increase STR, but will increase the speed at which you gain points).
Guns > Dom only
Maxim > Dom only + Ad for Penis Pump to buy.
And the Fashon mag actually is randomly 3 different sets:
a fem boost, a fashion boost, or both.
(the actual hidden fashion stat is apparently attached to one of the later paths in the office job).
Also the first 4 mags in Fairhaven, only work once, the first time you read them.
Their 1st initial boosts are more than each respective single mag, but its not much more.
Considering the mags restock once a week on Monday, it gives you a bit of a head start.
