I have finally decided to start HRT but I am at a loss and I am sorry for being an idiot...

I got my vial from HeraHRT (Thank you) and I got the syringes that u/A_Whole_Lot_Of_Not
recommended here... https://www.reddit.com/r/TransDIY/comments/1q6frmw/comment/ny79sui/?context=3
but I want to make sure I am doing it correctly and being a little over-cautious.
I just need to know if starting with 8mg so do I want to put EE to the number 8 in the syringe or am I doing it wrong?
Thank you and again I am sorry I know nothing about any of this.
