how much bac water for 20 mg of tirzepatide to mix with 30 tirzepatide mix with bacteriostatic water

The 5 mg vial + 2 mL gives 2.5 mg/mL, so a 2 mg start is a large, easy-to-measure 0.80 mL (80 units) convenient early on, though larger doses later exceed one barrel

Response timing varies

U100 insulin syringes, 0.5 mL barrel, 30G or 31G x 8 mm, ideally BD MICRO-FINE+ 0.5 mL U100 insulin syringes for the smallest needle gauge with reliable IU calibration

I agree with @Nackapan

177,178,179 Aspartic acid (Asp) is an essential energy source for the intestinal mucosa, and studies have shown that Asp can increase the abundance of Akkermansia in the intestine by regulating RIPK1 signaling, maintaining the integrity of the intestinal barrier, and promoting colonic mucosal functional repair

The honest boundary is that even the coherent pairing is a mechanistic hypothesis with no human validation, so the most defensible research posture is to study the single compound at its documented dose first, and treat any combination as a further, clearly-labelled research question rather than a default
