    Primary Hypo, TRT for 7 years, Good T, Low Free T

    I will check them out. Thanks. A few general questions about injections... The local doc suggested 100mg once per week into my glute muscle. In my case if the goal is to elevate both free T and E2, is there a preference for injection site? IM v.s. SubQ? The doc also seemed to think it was...

    Primary Hypo, TRT for 7 years, Good T, Low Free T

    I agree. The thought initially was that I would not use the AI (despite what that clinic suggested) unless I had evidence of high E2. This seemed at least possible if I were to take 200mg/test per week, but I'm going to try 100mg/wk and see where things end up with no AI. It would be...

    Primary Hypo, TRT for 7 years, Good T, Low Free T

    Those labs look great! That's closer to where I was when I started TRT but I'm pretty far off at the moment.

    Primary Hypo, TRT for 7 years, Good T, Low Free T

    So I found a local endo who is willing to prescribe me 100mg per week injectable without AI and it will only cost $30 when I need to refill. I'd like to start with this and see where my free testosterone and E2 end up.

    Primary Hypo, TRT for 7 years, Good T, Low Free T

    Thanks, yes I feel like I have to be my own advocate! That estradiol reading was from the most recent labs requested by the clinic. Believe I've had the sensitive test done once before and that e2 reading was also on the lower end. And yeah, my thought is I could recheck e2 (sensitive), T and...

    Primary Hypo, TRT for 7 years, Good T, Low Free T

    Yeah, I didn't actually get my SHBG tested recently, so unsure if it is high or low. Figured if my free test were that low, the SHBG was high. Think maybe the doc told me that, but as I mentioned, this is a "clinic". And I agree about the AI. I forgot to mention that I had actually tried Adex...

    Primary Hypo, TRT for 7 years, Good T, Low Free T

    Hi all, Please bear with me as I have a story to share and a number of questions. I'm 29 years old, about 6'1 215 20-22% BF, and been on TRT for over 7 years. I was diagnosed as primary with low testosterone (270 ng/dl), very high LH and FSH, small testicle volume (< kidney bean size), and...

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.
