Conversion info for going from 3ml to 1ml syrings

I started with 3ml syringes. My RX script was for taking 1ml (200mg TestC) once a week. I started with spacing that does out in half. So I used to bring it out to the 1/2ml mark for 100mg of TestC. Later I brought my does down to 80 so I would go to the mark before 1/2ml.

Now that I'm looking at this 1ml syringe, I want to make sure what mark to bring it to when I'm drawing. I want to inject 60mg of TestC. The bottle says 2000mg/10ml (200mg/ml). I'm thinking it should go to the 30units mark on the 1ml syringe? Is that correct? Thanks

You are correct
 
60 was the wrong number was thinking 180 a week but its supposed to be 160 in three shots now. So I need 54mg of TestC so I would look for the 27 mark on the syringe correct?

Thanks again
 
Do to my lower doses (17.5mg EOD) I use 27 gauge insulin syringes and inject in shoulders for shallow IM.
Same Here. Easy and pain free. I don't feel a thing.
WrenchHead, yes I think the most common syringe used for TRT injections is the 1 ML. 1ML = 100IU. Very precise dosing is possible with the insulin syringe. And yes, you can draw and inject with the same needle. Hope this helps a little.

Driven Mad and regretting it.

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.
