    How many 1 ml doses out of a 10ml vial?

    I am new to this. My doctor sends me a 10ml vial every 8 weeks. Is 2ml wasted in the process of taking eight 1 ml doses or is it possible to get a full ten 1 ml doses out of it? He prescribed 1ml weekly (8 weeks x 7 days = 56 days). After reading it seems smaller more frequent doses would be...

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.
