Changing Inj Frequency - Please Help

So I am changing from 1 injection of 180 mg per week going to two injections. I was previously using a 3cc syringe. I now purchased a 1 cc syringe. My plan is to inject 2 x per week for a total of 140mg. Would I inject 35 cc twice per week?

The testosterone vial I have is 1ml 200mg.
 
The easiest way to do the math is if your Testosterone was 1ml 100mg, you'd need 1.4ml a week to get 140mg, but since your Testosterone is 200mg per ml, you need half of that which is .75ml a week. And since you're trying to take twice a week, you need .35ml per injection so yes .35.

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.
