Cagrilintide - am I immune?!

There's more on survodutide and cagrilintide if you're comparing the two.

The unit versus milligram question is really worth pinning down - the effective dose range in milligrams is completely different from units, and running a protocol based on the wrong unit has caused real issues for people. What does your actual weekly total come out to in milligrams when you do the math?

The cagri response kicking in at 2.4 but not before is a really common pattern. A lot of people find it does nothing until they push past the entry doses. Not taking it same day as Tirz also helps avoid the overlap on sides. If the OP is at a lower cagri dose, there's more room to go.
