Not sure what you mean how do you dose it, when it says 100mg they mean per milliliter.
So to achieve 400mg of cypionate if you are doing Ttokkyo and Upjohn at the same time, that is 3 milliliters leaving no room for Deca in the pin. Sounds like your going to be doing 2 shots a week which is ideal anyway.
If you are not comfortable measuring out 1/2ml, then:
Tuesday - 1cc Ttokkyo cypionate, 1cc Deca (300mg/ml right?)
Friday - 2cc Upjohn Cypionate
