    3 month lab update...still feel blah...

    That's a very interesting take...I have often thought it was weird that reference ranges for certain blood tests can vary widely when in reality each person may need their levels to be kept in a smaller range to experience a true "homeostasis."

    3 month lab update...still feel blah...

    Definitely will be donating asap. You think although I still feel basically the same as where I started the solution may be to lower my test dosage? And I have complete faith in Defy and whichever protocol they believe is best, just want to become more educated and aware of what my body is...

    3 month lab update...still feel blah...

    Wow, that's really good advice. I honestly had not heard of the blood donation issue. I think I need to make a point of getting my BP tested once a month or so, would that be often enough? I'm going to read more into the E2 symptoms and see...perhaps trying it out for the next couple months...

    I should add, my PCP has previously mentioned I have some sort of harmless condition where my bilirubin appears slightly elevated.

    Switching to Defy

    Hey everybody! I wanted to start by saying the help I've received just by spending the last couple weeks on this site has been immense. I'm currently 6 months into my TRT journey and although I'm still excited to see progress moving forward, to date I haven't been too happy with the results. I...

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.
