It can be a symptom of anxiety, depression, or other mental health conditions, but can also be a learned behavior or a response to stress. Strategies for managing...

    Limited lab testing by endocrinologists

    A lot of times. I think we overthink it. You can keep it simple and do just as good as someone doing multiple tests. Most men do good on simple protocol.

    Personally, I don't believe it. I have kids and grandkids with over 130 IQs. Top 2% in comprehension and math. Their T is not super high.

    Personally, I've never had any issues with estrogen. My e2 runs on a low end of range. It doesn't mean others don't have issues with estrogen.

    Male...gaining slight fat with cellulite in thighs all of a sudden even with normal lab results

    As most members of this forum knows Belly fat is unhealthy fat. Below the waist is healthy fat. I would concentrate on squats and lots of walking it should firm up any fat you have on your hips or legs. I also had nerve damage in my right leg and tendon damage in my left leg. From when I broke...

    Sperm result after 3 months of HCG. What would you do?

    Stop TRT for now. If I was in your shoes I would definitely first try clomid. I believe it will be the best bet for you to become fertile again. It appears that most do better with low dose clomid, 12.5mg everyday or every other day or sometimes twice a week. You can buy it in Mexico or...

    Dosages

    I say would say a good starting dose would be 50 mg of T and 500 IU of HCG combined in the same syringe. My understanding is that's @Nelson Vergel protocol. Here's mine. I just had Labs done yesterday will post when available...

    Dosages

    No. What I mostly see is younger men need lower doses. The reason behind it is when you were at your peak. What was your T level at. Most younger men had lower levels when they were at their peak. Older men had higher levels when they were at their peak, so now the older men need higher levels...

    Testosterone dropped after a few months on the same dose

    Your first labs were done after 8 weeks. Not long enough. You need to wait at least 12 weeks. So your 2nd Labs I would consider more accurate. Every time you do Labs they will vary. Injecting is not 100% accurate and of course vial strength will vary. I feel my best at higher levels so I see...

    Does arthritic elbow mean I can't lift weights?

    This is what worked for me. Of course it may not work for you. I had tennis elbow about 3 years ago, it was very painful. I had to resort to pull-ups and chin-ups really stretch out my elbow. It did work for me. Now I'm completely pain-free.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
