Gosh, I've seen some doozies over the years. Hmm, some of the ones off the top of my head:
I don't need an AI, that hurts my gains!
Masteron/proviron are anti-estrogens, which is the same as an AI.
Deca dick comes from running anything other than a 2:1 ratio of test and nandrolone. (of course, which is supposed to be higher varies from place to place)
The key to bulking is drinking at LEAST a gallon of milk a day.
Don't masturbate or have sex on cycle, that will ruin your gains. This is double true if you're natty. (easily one of my favorites)
Oral only cycles are for guys that just want the fitness model look. As there aren't any needles, no PCT is needed either.
