Metabolic

GLP-2 TZ (Tirzepatide)

Appetite, blood sugar, and weight research

Quick answer

A 30 mg vial with 3 mL of water makes 10 mg/mL. A 2.5 mg dose is 25 units. Once a week, stepped up every 4 weeks.

Mix it
30 mg vial + 3 mL water
Draw
About 25 units on a U-100 syringe
How often
Once a week, same day each week
Store it
Refrigerate after mixing. Use within about 4 weeks.

What it is

Tirzepatide acts on two gut hormone pathways at once, GLP-1 and GIP. Research looks at appetite, how full you feel, and blood sugar control.

Most used for

  • Appetite and portion size
  • Body weight
  • Blood sugar control
  • Food noise and cravings

These are things researchers study. They are not promised results.

Dosing at a glance

These are the amounts used most often in research. Always start at the low end.

Vial size
10 mg to 60 mg
Dose range
2.5 mg to 15 mg per week, increased slowly
How often
Once a week, same day each week
Cycle length
Long term, dose stepped up every 4 weeks
Mix with
Bacteriostatic water (also called bac water or reconstitution solution).
Storage
Refrigerate after mixing. Use within about 4 weeks.

Mixing it

A common setup for GLP-2 TZ is a 30 mg vial with 3 mL of bac water.

That makes 10 mg per mL. A 2.5 mg dose is about 25 units on a standard insulin syringe.

Bacteriostatic water is all you need here. Acetic acid is only for powders that will not dissolve. See the mixing guide.
