When pinning twice a week, Tuesday and Saturday, how long to wait before having blood work completed? I know if injections are once a week, say Tuesday, then you would get tested the following Tuesday before your injection. I'm not sure about the procedure for 2W

Pick the day of your injection but do your blood draw BEFORE you inject. So if you inject Monday mornings and Thursday evenings, do your blood draw Thursday before you inject as an example.
 
ERO's advice is on the mark. The goal of more frequent injections is to minimize the peak and valley problems that can present with once-weekly shots. Hopefully, you'll find that your levels will be relatively smooth.

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.
