What is the half life of nandrolone decanoate? Some sources say 6 days, others say 6 to 12 days...

Trying to figure out when, if one were to inject say 40mg today, the ND would no longer be active/in one’s system.

From this graph it looks like the half-life for moderate dosages is 6 to 9 days, with a proportional increase in time to half-life as the dosage increases.

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.
