Good Morning,
When I started I read various things about the half-lives of TCyp and TEnan. 7 days. 10 days. One has a 1 day longer half life because of the longer ester.
I am aware that half-lives of all medications vary depending upon the patient. But a good estimate has clinical value for...
The relative level of SHBG has a pronounced effect on serum levels of testosterone delivered via TRT. This is through the influence of SHBG on the metabolic clearance rate of testosterone. But as far as I can tell the effect on the apparent half-lives of testosterone esters is subtle at best. Is...

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.
