Some of the guys I work out with know that i inject T. It has come up why then do I not put on more gains, I do heavy rssitance training and little cardio. I explained that I am on a theraputic dose. Shoot I take a paltry 30 mg twice a week to keep red blood cells in line, so i could never...
Comment: 125 mg per week was the lowest dose that provided statistically significant changes in lean body mass and fat mass.

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.
