Alternative to Stacking Tirzepatide and Cagrilintide?

I've only taken two minimum doses of Cagri so far stacking it with my 15mg Tirz. It most definitely worked. 1st dose of Cagri kind of hit me like a truck and 2nd not as much but still effective.

Anyways after reading about Cagri and this PH stuff etc, I reconstituted mine with BAC water 3 weeks ago. Just tested the PH and it was at around 7.

I'd rather not risk it if there are safer and just as effective options out there to stack with Tirz. Are there any?
