    Introduce an AI or Dosage Adjustment?

    Please, anyone, let me know what you think. Interesting that my E2 jumped from 63 at E3.5D injections and 200IU HCG EOD to 100 on a more frequent injection protocol (same weekly dose) and less HCG???

    Introduce an AI or Dosage Adjustment?

    Neither actually. I took my first AI dose a day after this blood draw. Maybe 1mg wasn't too high afterall?

    Introduce an AI or Dosage Adjustment?

    My ultra sensitive estradiol E2 results from this past Monday that I requested on my own after my change to EOD injections came back from Quest today at a whopping 100 on their scale of <=29. Should I be worried? How long before my AI should presumably lower that some? Thanks again

    Introduce an AI or Dosage Adjustment?

    Ok, I already took the 1mg yesterday. I will plan on starting with .25 e3.5days along with my HCG injections. This is a well known testosterone doctor which had me conflicted.

    Introduce an AI or Dosage Adjustment?

    I told my doctor that I switched to EOD Cypionate and 250IU E3.5D HCG. He prescribed .25mg Anastrozole EOD on injection day and asked me to front load 1mg for my first dose (yesterday). Thoughts? I am at this point almost hopeless..

    Introduce an AI or Dosage Adjustment?

    Question on starting EOD, on Monday, I injected my normal 70mg dose. Should I divide the remaining 70mg and take half today, half on Saturday and then start my routine of 40mg EOD on Monday? Also, is there benefit in cutting back my HCG from 200IU EOD to 250IU E3.5D?

    Introduce an AI or Dosage Adjustment?

    I'll try EOD injecrions. Would you recommend I keep my HCG dosage of 200IU EOD the same? I've only been on HCG for 2 weeks and I guess I haven't noticed anything from that specifically. What is strange is with my increased testosterone, my low libido and ED issues are exactly the same as Pre...

    Introduce an AI or Dosage Adjustment?

    I posted a few weeks back about having no benefits of TRT after a few weeks in with a protocol of 70mg E3.5D and 200IU of HCG EOD (HCG only started for the last 2 weeks..and I had no effects of 4 weeks TRT without it). I am now in my 7th week, still with no effects. My libido and erections are...

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.
