Sides are possible thinning of the hair, limp dick if you dont counter it with test, zits, moodiness, and gyno in very few cases. I did a 6 week 75mg EOD cycle and started getting ta sore and swollen nip so I stopped in week 5. Your strength gains will be terrific, will nake you vascular, helps in cutting, and can also aid in size to an extent. I had no sides other than the nip problem, but everyone is different.
