Tirz + Reta or Cagri... or split dose?

I'm at 6mg Tirz and just got some Cagri. Thinking I'll try your split approach and check results before going higher - I prefer starting low.
 
Why are insulin vials 90 days, compounded meds 90 days, but the water says 28? Is 28 some industry safety thing or did someone just make it up? I go 90 days in a ziploc in the fridge, filter everything to new vials. Would love to see a real test of old water.
 
Nausea at 6mg is worth troubleshooting before stacking. The first thing to look at: is it consistent through the week or peaks in the 24-48h after injection? If it's injection-day nausea specifically, splitting the weekly dose into two smaller shots several days apart often helps substantially. If it's persistent through the week, that's a different profile and might point to dose being too high for your current adaptation level. Stacking Reta at that point could amplify the GI effects before you've found stability on tirz. Cagrilintide works differently (amylin analog) and is generally less nauseating, but it's less available. The split dose approach is worth trying first before adding a second compound.
 
Nausea at 6mg is often a titration signal rather than a ceiling - the stomach needs more time to adapt than the scale response suggests. Splitting the 6mg into two 3mg doses weekly can reduce peak plasma levels and significantly lower the GI response. Adding Reta on top of active nausea isn't the move - the glucagon receptor activation typically amplifies GI effects. The cleaner path is stabilizing at 6mg with split dosing first, then evaluating whether the nausea resolved before deciding on a stack.
 
Switching to Reta after a solid run on Tirz and pushing the dose aggressively to close the gap is a pattern that comes up here fairly often. The question worth asking: are side effects still active at the current dose? If tolerance is holding and the pace is good, the approach makes sense. If side effect burden is still present, a step back and slower re-titration usually preserves more progress while reducing the symptom load.
 
At 6mg Tirz with persistent nausea, injection day food approach is the first variable to check. Stacking Reta makes sense once baseline side effects settle - it adds a distinct mechanism rather than more of the same input.
 
That stash lineup covers the major bases - a year of multi-compound supply is solid by any standard, and the combinations give you real flexibility to dial in what works.
