Is there an internet calculator or way to calculate how much mg of test you would be getting per amount of mL you are injecting.. its easy to calculate using .25mL .50mL etc for 200mg/mL test-c, but where I have been running into the problem is when I’m trying to get let’s say 125mg per week split in two doses.

I obviously suck at math and would like to just plot a number in and have it calculate the mL amount for the intended mg. I use a .50 mL insulin syringe and it would be outstanding if I knew what mg it is at the different marks eg .35 .36 .37 mL to make it more precise.
