Men do experience side effects; it happens with any drug. I was one of those men.
Cut your dosage in half and try that. I've done that for the last 5 months and haven't had ANY problems this time. Libido is the same, no tender nipples, no funky semen, no weak erections. I still had my crown thicken up and a little bit of thickening in my front area. It's probably not as much as I would achieve at full dosage, but it's an excellent trade-off.
