Low doses year round is a non issue. Plus the quality of life improvement you get far outweights the possible issues.
I think there are other aspects to the bodybuilding "life style" that are way more dangerous: abuse of pain killers, over eating, no cardio, not moving very much, using orals, gay4p etc.
Abuse is bad. I know most people want to look very huge but injecting 4 grams of steroids when your body produces about 100 mg a week is just playing with fire.
Besides, I'm with Groink and AJ: using 250 mg a week WILL get you good results in the long term (it will take years instead of weeks but worth it IMO). Frankly, I wish I had fallen to the dark side a couple of years ago. I probably would kept on lifting instead of getting discouraged and stopping to do cardio only instead.
I was wondering if I should stop but seeing my bloodwork immaculate (my cholesterol actually got lower, maybe because of the small amount of equi I am using, plus all of my joint pains are just gone... low dose equi is amazing, I'm taking 100 mg test/150 mgs equi a week, I know pussy dosage but works for ME), there is no reason to come off. ...
Plus, genetics is huge, biggest factor by far.
