Metabolic
GLP-3 RT (Retatrutide)
Three-pathway metabolic research compound
Quick answer
A 10 mg vial with 2 mL of water makes 5 mg/mL. A 1 mg dose is 20 units. Once a week, stepped up every 4 weeks.
- Mix it
- 10 mg vial + 2 mL water
- Draw
- About 20 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
Retatrutide acts on three pathways: GLP-1, GIP, and glucagon. The third pathway is linked to energy burn, which is what separates it from tirzepatide in research.
Most used for
- Body weight
- Appetite control
- Liver fat
- Metabolic rate
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 30 mg
- Dose range
- 1 mg to 12 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-3 RT is a 10 mg vial with 2 mL of bac water.
That makes 5 mg per mL. A 1 mg dose is about 20 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.
