at low doses (20mg ED) the sides arent that bad at all, barely even get chapped lips....when you venture into the moderate to high dosages is when the shit hits the fan for side effects, you will experience:
Severely Dry skin and Lips
Higher sensitivity to sunlight (you will burn very easy)
Its very liver toxic at the recommended dosage (80mgED)
Nose Bleeds
Cracked lips
Dry skin inside of nose(which usually causes the nosebleeds)
Blurred vision
Probably some others also, cant think of them all of the top of my head.
Now all of these side effects can be avoided with taking a low dose (20mgED) and the results will be unreal, I took 40mg for 2 months then down to 20mg ED for the next 4 months and stayed zit free on and off cycle, and believe me I used to get HORRIBLE back acne from AAS use
