.45ml of 200mg/ml Testosterone is 90mg Testosterone


This is the first post that addresses my own confusion. I'm new to TRT and when I went home yesterday, I assumed I was starting out with 45mg Testosterone Cypionate twice a week for a total of 90mg TC a week. 


 I thought about it this morning and wanted clarification as I'm taking .45ml of 200mg/ml TC, meaning Im taking 90mg per dose twice a week for a total of 180mg Testosterone Cypionate per week if I am correct. 


I get the posters confusion as this is all foreign aside from the reading Ive done here and a T-nation and Im still not 100%. I have asked my doctor to clarify my mg dose, so I dont confuse my ml dose with mg of medication. I am assuming I will hear back today but this was a hard thing to double check online. Its very wordy.


I do understand now from the OP post that mg and ml were being, I think accidentally exchanged.  I had to bounce this off my wifes big head in order to understand.
