I have been suffering from weight gain, fatigue and muscle loss. Can anyone give me any advice on supplements, what to get tested for? What the likely cause of this could be?
Loss of androgen function or metabolism. Get your Testosterone levels checked.
I also have those side effects. My Free and Total T levels have been in upper levels though. There have been some guys here who have been able to regain muscle by boosting T. Have full panel hormone testing done if you can. Most docs who attempt to treat PFS will begin with HPTA restart protocol. ie, low dose clomid over time.
