Actually, they aren't as crazy as it sounds, just misguided. The truth is that many studies of testosterone and body anthropometry have shown that must growth with androgens is mostly in the trunk and shoulder girdle. That is one of the things that makes a man a man in puberty. However, a recent study of deca showed growth mostly in the shoulder girdle and trunk, too. The point is, the more androgenic the substance, the more growth is concentrated in the trunk and shoulder girdle. The more "anabolic" and less androgenic, like say primo, the less classically "male" the resulting growth and buildup will be. However, there would be no difference between one testosterone preparation and another, and deca and eq won't avoid this androgenic look either. You would have to use only primo, and then your growth would be limited. Most people mix testosterone and a general less androgenic anabolic (deca or eq) for this reason. Lastly, it is primarily the broad shouldered thick look that makes a man look like a good-looking, strong man, so why would you want to avoid that? For your purposes too, the whole trunk and shoulder girdle are implicated in these studies, so you won't hit your traps and not your delts.
