I am almost 6 years into TRT and I am thinking about stopping if I could get my HPTA axis to restart. I have very low SHBG and TRT does indeed feel like I am injecting water - as does HCG, and topical T feels like I am applying lotion. Thyroid meds seem to have no effect either.


I literally have no idea what injecting Test feels like because I have never felt anything. My life consists of low to no libido, seriously sh*tty recovery from exercise and a strong desire to take a nap every day after lunch even though I am otherwise healthy. Not obese, not diabetic, not depressed, no sleep apnea. Just tired of TRT doing next to nothing.

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.
