I did not get my rad 140 from a form sponsor for stop because I know you're going to ask me. I bought it from another company. I regret my decision but I'm looking for help figuring out how to fix the issue. I have been taking rad 140 15 mg a day and I'm 3 weeks and I'm having erection issues. I cannot get it up. I stopped using it and 2 weeks later the problem is still here. What can I do to fix it
