    Relationship between testosterone levels and ED

    I hear you ERO, I was the same from an early age. Very high drive but as soon as I hit 40 this year it's like my libido just went down a couple of notches. I bet if you ask my wife she would probably tell you its not a bad thing ;)

    Relationship between testosterone levels and ED

    ERO, do you have any test result numbers for your DHT level? I have low testosterone but high DHT and have very little issue with libido. Just curious if there is a co-relation between the two?

    Assistance evaluating thyroid blood test levels

    Thanks Chris! I start taking my temps tomorrow and post them up once I have reached the 5 day mark. I will try and get those other tests organized as well. Can you comment on how much inactivity can contribute to thyroid levels? I am just starting back in the gym after a very long absence and...

    Assistance evaluating thyroid blood test levels

    I was wondering if someone could have a look at these thyroid numbers and let me know what your thoughts are. I recently started TRT due to low testosterone in my lab reports but after researching this site I suspect I may have thyroid issues as I seem to suffer from a lot of the symptoms which...

    Lab results, just started TRT

    Do you guys know is there a way to narrow down the reason for low T? Would my blood labs indicate if I was a case of primary or secondary hypogonadism? I had surgery for a vericocele when I was in my teens but have had no issue fathering children so I doubt that is a cause. The TRT doc I am...

    Lab results, just started TRT

    Thanks Vince, I actually did have one question regarding the HCG. Someone from another board recommended just using HCG to try and restart my own testosterone thereby not having to use test for the remainder of my time on earth. Is this an option for some? I have read really mixed reviews about...

    Lab results, just started TRT

    Hi guys, he actually did prescribe me TRT at 50mg twice per week and bloods will be taken again in 3 months and reviewed. This is an anti aging clinic and from what I can tell he is fairly up to date on everything but because I am in Canada my options are limited. The reason I went this route...

    Lab results, just started TRT

    Can anyone comment? I should also say he prescribed 50mg test twice per week as well as HCG 250 units two times a week.

    Lab results, just started TRT

    Hi everyone, I just got my labs back from my TRT doctor. Just wondering if you guys could go over it and give me any input. The doctor went through the values quickly he thought my cholesterol was borderline and that I need to keep an eye on that as well as my iron levels. I don't suffer from...

    Low T no sexual sides?

    Thanks Guys, So here are some of the numbers I could find from my first test I did in 2013, I asked to have my Testosterone and Thyroid levels checked. Below are the results so if someone could kindly interpret that would be great! Testosterone 8.2 nmol/L the reference range on the form says...

    Low T no sexual sides?

    Hi Nelson, The only thing I can say is that my erections are less rigid for lack of a better word but I doubt that puts me in the realm of ED. I have sleep apnea and have been on cpap therapy for the past 4 years. The only medication I take is nexium for GERD which is a result of a faulty...

    Low T no sexual sides?

    Hey All, I have had a number of blood tests that have come back with my T levels below the normal. I don't have any issues maintaining an erection and "getting the job done" and enjoy it when I am doing it but I would say my drive has decreased fairly significantly. My main issues are lack of...

    Looking for some assistance with lab results

    Hey, thanks a ton for your input guys, that is really helpful information. I wonder why so many doctors/practitioners are so against TRT? She was dead set on convincing me my levels are perfectly normal?

Free Testosterone

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