Howdy y'all,
As I've posted about in the past, I've been taking HCG Monotherapy for low T for about seven years now with good results - my last bloodwork had my total T at 707ng/dL with no change to my total weekly dosage since I started in 2017 (just tweaks to my dosing protocol)...

For many years, the ‘KNDy hypothesis’ has been the main mechanistic explanation of the pulsatile secretion of gonadotropin hormones. New research in Cell Reports proposes an...

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.
