    Wouldn’t an ai suppress estrogen?

    5 months into TRT

    Also if it matters, my shbg level before treatment was 20. At that time I was only on clomid for a few weeks.

    5 months into TRT

    Okay, I had the pharmacist order 29g needles so I’ll give the ed protocol a try. My only concern is that I won’t get symptom relief with anything under 600. Is it possible with low shbg to still maintain a steady upper-half range of total t while managing e with an ai ed or eod? For instance...

    5 months into TRT

    If my total test was only 599 on the third day after a shot of 100mg, wouldn’t it drop even lower if I dropped to say 20-25mg a day? That third day after a shot is when I start to feel a return in symptoms (ED, no morning wood, low sex drive, less energy). This makes me think that 599 is too low...

    5 months into TRT

    I am just as surprised with my total t. I thought it would’ve been higher as well. I’m thinking that with my low shbg I must be metabolizing it fast. I’ve been splitting the 200mg up into two shots a week since I’ve started. I’ve also tried 50mg eod but I started feeling like my levels were...

    5 months into TRT

    Hi all, So I started testosterone replacement about 5 months ago after testing low for total and free T over the span of a year and a half. My Doctor started me on transdermals but I eventually switched over to injections. I started on 100mg test cypionate twice/week. After a month on only the...

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.
