    Why is it a bad idea to take clomid/gonadorelin while on TRT?

    I have read in this and other forums that taking clomid, gonadorelin, or kisspeptin while on TRT is a waste - that those things are used more for PCT, to regain testicular function. But why is it wasteful, or even contraindicated, to use those medications while on TRT? How does one harm the...

    TL;DR: Over a period of seven weeks, treatment with GnRH and enclomiphene raised LH and FSH from around 0.1 mIU/mL to about 1.0 mIU/mL, even though TRT and hCG dosing were continued. Subjective results have been encouraging. I had written previously on the subject of GnRH suppression on TRT...

    Admittedly the last thing we need is some other nebulous danger to worry about that may not even exist. Read on at your peril. TL;DR: Testosterone replacement therapy suppresses the production of GnRH. Receptors for GnRH are found in places besides the pituitary. One animal model suggests GnRH...

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.
