Retatrutide is a new peptide therapy being used for weight management and metabolic support. As with any peptide or compounded injectable, how you store it can affect how well it works. At Amazing Meds, we want to make sure our patients get the full benefit of their treatment. That starts with understanding the proper way to handle and store your medication.
Does retatrutide need to be refrigerated before use?
Yes, retatrutide should be stored in the refrigerator before it is mixed or injected. The proper temperature range is between 36°F and 46°F (2°C to 8°C). Keeping it cold helps protect the active ingredients from breaking down too early. If you have retatrutide in powder form, it should be kept in its original vial, inside a clean and dry refrigerator.
Do not store the medication in the freezer unless directed by a healthcare professional. Freezing it can damage the peptide, especially if it goes through repeated freeze-thaw cycles. If your refrigerator has cold spots that might freeze liquids, keep the vial in the middle or a produce drawer where temperatures stay more stable.
Can retatrutide be kept at room temperature?
Unmixed retatrutide (the powder) can sometimes be kept at room temperature for short periods, but it’s not ideal. Warm temperatures, moisture, and light can all cause the medication to lose strength. If you plan to store it for more than a few days before use, it should be kept in the fridge.
If you accidentally leave a vial out at room temperature for a few hours, it’s probably still fine, but it’s better not to make a habit of it. Always return it to the refrigerator as soon as you can.
What about retatrutide that has already been mixed?
Once you mix retatrutide with bacteriostatic water (or another approved diluent), it becomes much more sensitive to heat and contamination. At this point, the vial or pen must be kept in the refrigerator. After mixing, it can usually be used for up to 30 days when stored properly in the fridge.
Make sure the container is tightly sealed and kept away from direct light. If you notice any color changes, cloudiness, or particles floating in the solution, do not use it. Those are signs that the product may have been compromised.
Can you freeze retatrutide?
No. Do not freeze retatrutide after it’s been mixed. Freezing can change the shape of the peptide, which may make it less effective or even unusable. The medication should stay in the fridge, but never go in the freezer. If you freeze a vial by mistake, call your provider or pharmacy before using it.
How long can retatrutide stay out of the fridge?
For short periods, such as during travel or if you’re moving the vial from one location to another, retatrutide can be kept at room temperature, but only for a limited time. In general, try to keep it out of the refrigerator for less than 24 hours, and always return it to the fridge as soon as possible.
If you travel often, use an insulated medication cooler with a cold pack to maintain safe temperatures. Avoid letting the medication sit in a hot car, near heaters, or under direct sunlight.
What signs show that retatrutide is no longer good?
Here are some signs that your medication may have gone bad:
- The liquid looks cloudy or discolored
- You see small particles floating in it
- The vial or pen was left out of the fridge for too long
- It smells strange or looks different than when you first got it
If you notice anything unusual, don’t inject it. Contact your provider or pharmacy and ask for guidance.
