That image brings me memories...
As a young teenager gym rat in the early 90's i had a "imported muscle magazine" with that ad. on the back cover.
I lent said magazine to a buddy who was also a gym rat, so he could write down all the "secret" workouts the pros were doing.
After seeing lots of colorful ads showing magical muscle building supplements, he started to ask his mom some money to buy "vitamin supplements".
One day his mom saw the magazine in his room and came screaming holding the magazine, "I will never give you money to buy those "medicines"!
You have no idea of how ugly you will get with your legs covered in veins like that!
Good times.
