Pump Buddy Magazine

Pump Buddy Magazine (or Pump Buddy) is a bodybuilding related magazine in Grand Theft Auto V. Its advert can be seen in the first trailer at Muscle Sands Gym. The magazine's motto is "Plenty of issues to work out!". It is also sponsoring Muscle Sands, as the sign says.

Trivia

 * The word "PUMP" on the sign is edited with a yellow spray to "BUM" (with the last P removed and the first P changed to a B). Thus the full name would be "Bum Buddy", referring to the common homosexuality of budybuilders.
