Insulin vs tuberculin syringe

I am currently using 25 gauge, 5/8" tuberculin syringe.

I am considering going to 27 gauge, 1/2" and see some on the forum are using the insulin syringe.

With the tuberculin syringe the scale on the barrel is marked in .01 increments. If I understand correctly the insulin syringes are marked in in 2 "units".

If you are injecting 0.35 of 200ml Test Cyp how on the insulin syringe are you getting the correct dosage since in is in units of 2? Are you all just eyeing the dosage?

Thanks.
 
On my Easy Touch insulin syringe, 10 equals 20 mg of testosterone from my 200ml testosterone cypionate vial.

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.
