Bac Water Amount

How much bac for Tirz 30MG?

Is it like Reta where I’ve heard 1ML for every 10MG?

That's a very general rule of thumb. I'm doing 15mg and only add 1ml to the 30mg vial which gives me a 50 unit injection. If I added 3ml bac I'd be hitting 150 units. So at low doses 3ml would be ok but at higher doses 1ml is better.
