i have a 3cc syringe. my problem is for ex: between 1 & 2cc's there are 4 lines. how can u determine the half way mark. i need to split my deca & test shots to 2 times a week. test 400mgs/wk, deca 300mgs/wk. so i would have to do 150mgs of deca & 200mgs of test, but i cant figure out the half way mark.![]()
