    First Blood Work after 6 weeks of Injections-Canadian Numbers

    Maybe it seemed he was a bit annoyed but just overall get a sense that he has his way of doing things and keep things short and to the point. I am leaning towards heading to the US and just paying for it myself but again not sure exactly what I would do with the results as it seems the doctor...

    First Blood Work after 6 weeks of Injections-Canadian Numbers

    So went and saw Dr. Greenspan approx. two weeks ago. Protocol is to stay the same of 100mg a week and then redo blood work in 3 months to see if test has gone up more. I have gone ahead and decided to split the dose this time around and do 50mg every 3.5 days. Asked him to test for SHBG and his...

    First Blood Work after 6 weeks of Injections-Canadian Numbers

    Yes I have PSA from June which was .70. I will ask for the most important ones and then see how he reacts to that and bring up DHT and DHEA. How often should I get PSA done once on TRT?

    First Blood Work after 6 weeks of Injections-Canadian Numbers

    Thanks CoastWatcher! I will push for those tests you recommend. Hopefully he is open to it. Why test DHT and DHEA? I will do a search for those here but curious on your take on the importance of them. Appreciate the help! Thanks, AR

    First Blood Work after 6 weeks of Injections-Canadian Numbers

    So had my first follow up blood work done after 6 weeks of 100mg a week via SubQ injection. I am Canadian and with Dr. Greenspan in Ontario, Canada. He did not measure my SHBG levels for some reason or estradiol. I know that estradiol tests in Canada can measure high anyway so I guess not a big...

    More magnesium, more free testosterone

    Men with more magnesium in their blood are likely to have a higher amount of free testosterone in their body. Chemical analysts draw this conclusion in an article published in the Journal of Pharmaceutical and Biomedical Analysis. http://www.ergo-log.com/magnesiumtest.html

    Hi Madman, Finally got my referral to Dr. Greenspan and see him next Wednesday. Curious if you can tell me a bit more about his approach and what sort of treatment he has given you and how your numbers have turned around? Any input would be greatly appreciated. Thanks, AR

    Thanks for the welcome Madman. I have been reading your past posts and have learned a lot. Thanks for sharing your experience and what to potentially expect with Greenspan. Hope I can get a second opinion and a referral from my GP. Yeah, never really occurred to me that my testosterone would...

    That is odd. I will aim to get a referral to Greenspan then. Do doctors mind if you bring lab work in from the US as I was planning on heading over to Michigan to go the needed blood work while I wait for my referral? Thanks again!

    Thanks CoastWatcher. Much appreciated. I will get my GP to get a referral to Dr. Greenspan. A doctor friend of mine recommended Dr. Adam Millar. Have you heard good things about him?

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

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