1ml vials

It's like trying to get the very last drop out of any vial, I leave it upended with the 1/2" needle barely in there just hanging, to get that last drop. I get it with those 1ml vials, its frustrating.
 
When I go to get my refill, Walgreens has been giving me 12 1ml vials even though my prescription is for 10 ml. I wonder if this is why?
 
Yep, they often overfill them because you waste a small amount with every injection if you're using syringes with removable needles.
 
I get the Pfizer 1ml bottles from Costco. Has to do with insurance since they will only cover 4ml per month. Each of those vials has 240mg in them. I can get (4) 60mg injections out of each bottle. I use insulin syringes so there is no waste.

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.
