How to Mix Retatrutide
You will need:
- 1 vial Retatrutide 10mg (lyophilized powder)
- 2ml Bacteriostatic Water (BAC water)
- 1 syringe (3ml or 5ml)
- Alcohol swabs
Step-by-Step Instructions:
- Clean the tops of both the Retatrutide vial and the BAC water vial with alcohol swabs.
- Draw 2ml of BAC water into your syringe.
- Slowly inject the water into the Retatrutide vial by letting it run down the side of the glass (avoid direct pressure onto the powder). Please ensure you hold the plunger firmly to prevent fast water intake. The vial will quickly draw in the water due to the vacuum inside.
- Gently swirl (do not shake) the vial until the solution is fully dissolved and clear.
- Once mixed, store the vial in a refrigerator between 3°C and 6°C, protected with foil.
