Vial cap?

Rookie question. Went to learn how to self inject at my Endo's office today. When the nurse opened the box containing my vial, she popped off a blue cap that covers the membrane and threw it away. She stated that it is not necessary to keep it on the vial for storage. Is this true? I figured it was some sort of safety cap for a new vial.
 
In the hospital, if we were doing chemo drugs from vials, the vial top was considered sterile if you used it immediately after removing the cap. A second usage would then require cleaning with an alcohol wipe.
Note on worrying you are screwing up: Although it is good to be cautious, and clean the cap carefully, if you forget, there is very little risk to your health. I worked with many diabetics over my retirement career in public health, and I asked questions about this exact topic every admission to service. Many people reuse needles for testing, and also reuse diabetic syringes more than once. Same goes with air bubbles, it would take a huge amount to kill someone.Actually a small bubble at the end of an IM injection prevents fluid leaking up the needle track. Never had any issues with these things, that break every rule RN's learn in school. We won't discuss how many people who self-cath (for urine) rewashed the (one time usage) catheters in the dishwasher, some of you may be preparing to eat.

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.
