Help with calculating testosterone injection volume

This is a stupid question I'm sure to the more experienced guys on the forum. I was prescribed a 10ml vial of testosterone in a concentration of 200mg of test per ml. The doctor prescribed me .25ml twice per week which I think is 50mg for each injection. I have 1cc syringes. How much do I draw into the syringe for each injection? Thanks

Your test is 200 mg... per ml AND per cc. The cc and ml are the same. .25ml is .25cc, so as Tom says draw to 25 on the syringe. That will get you 50mg of testosterone.

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.
