I'm going on my third week at 5iu's. First time running growth. I started at 1.5, then to 2,3,4,5. Moved up every week. I'm reading about people having numbness at 1iu. The only side I'm getting is sweating a ton in the gym again, hot flashes and facial hair might be growing a little faster. Does some people just not experience the numbness or do I need to keep uping the dosage?
