What I always do when I'm facing a yes or no question is make two lists. It's dorky but it usually clears things up in a jiffy.
List A: This should include the benefits such as increased muscle gain, increased self-satisfaction, potential romances?, etc...
List B: This should include the drawbacks, which would be cost, legality, and health benefits like severe acne, jaundice, cardiovascular or heart disease, stunted growth, psychological effects (increased aggresiveness, mood swings, sleeping disorders), testicular atrophy (shrinkage), erectile dysfunction, impotence, etc
Then you look at which list seems more appealing. Or you can cross out things on the drawbacks list that you wouldn't like to have and cross off things on the benefits list that you can do without because of drawbacks.
Also, look at the benefits and check to see if they can be acheived elsewhere. I'm guessing they could. Check the drawbacks for items that are unbearable...and I'm guessing you'll find alot.
I don't care how much muscle I have or don't have. I'm just glad my penis works and I am mentally stable.
But if the benefits are all too appealing, start using juice like you've got scurvy.
