Tirz-Reta dosing

Hey all, I saw a popular peptide company is starting to make a blend of Tirz-Reta. It is 25MG of Tirzepatide and 20MG of Retatrutide. I have been taking Tirz for about a year now and am on a 7mg dose weekly. I've lost about 90lbs.

How would you dose out a blend like this in the calculator? I know how to dose out my tirz, but I know reta you would start much lower than tirz. What would a dosing schedule look like for this?
