Great info, Gene...thanks.  I have an unmixed/unconstituted vial of HCG that I thought was safe to store at room temperature until reconstitution.  I've had it in the back of a dark cabinet at room temperature for about 3 weeks.  Based on what you are saying, I only have about 5 weeks left before I would need to use it; is that correct?


I won't be ready for that vial yet as I still have a good amount of reconstituted HCG (stored in the fridge) left.  Would transferring the unmixed/unconstituted vial of HCG into the fridge or freezer extend its life or should I count that vial as a casualty of inexperience?

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.
