Retatrutide 30mg Dosing
Ensure that you sterilise the cartridge stopper with an alcohol swab before connecting the needle to the pen.
1. Prime the pen to remove any trapped air by turning the dial in increments of 5 to 10 units and pressing the button until a small drop of liquid appears at the tip of the needle.
2. Adjust the dose on the window to the recommended starting dose. Double check your dose before getting ready to insert the needle.
3. First sterilise the area to be injected with an alcohol swab. Pinch the skin on the area you plan to inject (usually the abdominal area) between your fingers, then insert the needle at a 90 degree angle to the full length of the needle, hold in place then press the button on the pen to fully dispense the peptide solution. Hold the needle in place for 5 to 10 seconds to allow the solution to diffuse into the tissue.
Retatrutide 30mg Dosing Recommendation (3ml Vial)
NEVER SHARE YOUR NEEDLES OR PEN WITH ANYONE.

Ensure you sterilise the cartridge stopper first by wiping the rubber port with an alcohol swab- do not touch the stopper once sterilised. Do not touch opened needles. Use a new needle for each injection. If you are reusing needles, wipe the needle tip with an alcohol swab before using.
