    Anxiety about IM injections

    Sweet mother, I would have experienced anxiety too about using that harpoon 2x per week! My favorite insulin needle for delt was 29 gauge x 1/2". I have long since moved on to subq with 31 gauge x 5/16

    I need help getting dialed in

    I learned my lesson on that tendency early in the TRT process. I was 100% certain that [x] was causing [y], but eventually realized that you need to give it time before making proclamations. I look back at my journal and see so many foolish conclusions later proven wrong. Now I give it at...

    I need help getting dialed in

    So you stopped taking DHEA and Preg? I saw above that you had previously concluded that these two were the answer to the riddle.

    6 months into TRT - minimal effects - no libido - thinking of stopping?

    I wouldn't recommend chasing that 20s dragon. TRT's suppression of HTPA system makes that virtually impossible. My TRT benchmark is to feel better than I did pre-TRT in my late 40s (which was basically shit)

    Truth About Testosterone and Your Libido

    This thread reminded me to give Selegiline a shot to increase dopamine which @Cataceous mentioned in post below. Cat - are you still microdosing Selegiline? https://www.excelmale.com/forum/threads/using-protocol-change-to-spike-dopamine.25879/#post-231118...

    Truth About Testosterone and Your Libido

    I don't know how I missed this one thanks Madman. Should be required reading for men contemplating TRT. I was one of the suckers who fell for the Low T marktease about libido (although TRT has certainly been helpful in other respects) This quote still holds the key IMO: Dopamine, serotonin...

    Low Total T and Normal Free T. Became hyper sensitive after HCG

    Where did you read this? Many of us low dose guys can confirm that even small amounts (well below 9mg per day) shut down LH. I would agree that there are degrees of HTPA suppression - i.e., 200mg per week versus 50mg per week - although even that is debatable

    Low Total T and Normal Free T. Became hyper sensitive after HCG

    5mg per week? I'm all for micro dosing, but that is extreme. I have found that 6mg of Enanthate daily is low as I can go and still get some benefit from the TRT

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.
