There's a college in my town that is looking for volunteers for a clinical study of testosterone and dutasteride taken together for 20 weeks. The test could be any one of four study groups at 50, 150 300, or 600mg per day, dutas at 2.5m. Can anyone tell me about risks or side effects of participating in this? I don't think that they are giving an estrogen blocker.....should I do this or not? I'm obviously new to all of this. Thanks for any advice.
