Key Takeaways

• Compounded semaglutide is a customized version of semaglutide, prepared by specialized pharmacies. It is often used for weight management and blood sugar control when commercially available options are limited.
• Shelf life varies: Liquid formulations typically last 4 to 6 weeks and Lyophilized (freeze-dried) powder can remain stable for several months before mixing with proper storage. Proper refrigeration and protection from heat and light help maintain potency. 
• Improper storage can cause the medication to degrade, reducing effectiveness and potentially leading to adverse effects.
• Using expired compounded semaglutide may result in reduced potency or health risks. Always check expiration dates and consult a healthcare provider if unsure.

If you’re using compounded semaglutide, you want it to work as effectively as possible—but how long does it actually last? Since compounded medications don’t always have standardized expiration dates, it’s understandable to have concerns about shelf life, potency, and safety.

The good news? With proper storage, you can help ensure your semaglutide remains effective for as long as possible. 

In this guide, we’ll walk you through everything you need to know about how long compounded semaglutide lasts, what affects its shelf life, and how to store it correctly—so you can feel confident you’re getting the most out of your treatment.

What is Compounded Semaglutide?

Compounded semaglutide is a custom-made version of the medication, prepared by specialized compounding pharmacies. Unlike commercially manufactured semaglutide (such as Ozempic or Wegovy), compounded versions are created when brand-name options are unavailable or when patients need a tailored formulation.

These formulations often combine semaglutide with other ingredients, such as vitamin B12, to enhance absorption or reduce side effects. 

While compounded semaglutide can be a cost-effective alternative, its quality, potency, and shelf life depend on proper formulation and storage.

Because compounded medications are not FDA-approved in the same way as commercial versions, it’s essential to get them from a reputable pharmacy that follows strict quality standards. If you’re considering compounded semaglutide, IVY RX provides high-quality options to help you stay on track with your weight loss goals.

How Long Does Compounded Semaglutide Last?

The shelf life of compounded semaglutide depends on its formulation, storage conditions, and whether it’s in liquid or powder form. Typically:

• Liquid compounded semaglutide (pre-mixed) lasts around 4-6 weeks when stored properly in the refrigerator.
• Lyophilized (freeze-dried) semaglutide powder can remain stable for several months if kept in a cool, dry place before being reconstituted.

Proper storage is key to maintaining potency. Heat, light, or contamination exposure can cause the medication to degrade more quickly, reducing its effectiveness. 

Factors Affecting Compounded Semaglutide Shelf Life

Several factors influence how long compounded semaglutide remains effective. Understanding these can help you store and use your medication properly for the best results.

1. Storage Temperature

Temperature control is the most critical factor affecting semaglutide’s shelf life. It should be stored at 36-46°F (2-8°C) in the refrigerator. If left at room temperature for extended periods:

• It may lose potency faster, making it less effective.
• Exposure to temperatures above 86°F (30°C) can degrade the medication rapidly, rendering it unusable.
• Freezing can damage the protein structure, making it ineffective even after thawing.

If your semaglutide has been left out of the fridge, check the pharmacy guidelines on how long it remains stable at room temperature. When in doubt, consult a pharmacist before using it.

2. Light Exposure

Semaglutide is sensitive to light, which can break down its active compounds over time. To prevent degradation:

• Always store vials in their original opaque packaging or a dark area of the fridge.
• Avoid placing the medication near direct sunlight or under strong artificial lighting for long periods.
• If using pre-filled syringes, keep them covered when not in use.
  ‍

3. Air & Moisture Exposure

Once opened or mixed, compounded semaglutide is more vulnerable to air and moisture, which can shorten its shelf life.

• Multi-dose vials should be sealed tightly after each use.
• Lyophilized (freeze-dried) semaglutide should be stored in a dry environment before being reconstituted.
• Avoid leaving syringes or vials open to humid conditions, such as bathrooms or kitchens.
  ‍

4. Contamination Risks

Improper handling can lead to bacterial contamination, which not only affects potency but also increases infection risk.

• Always use sterile syringes and needles.
• Clean the vial’s rubber stopper with an alcohol swab before drawing a dose.
• Avoid touching the needle or vial opening to minimize contamination.

‍

5. Formulation Type

The type of compounded semaglutide you use will also determine its shelf life:

• Liquid formulations: Typically last 4 to 6 weeks when stored properly.
• Lyophilized (freeze-dried) powder: Can remain stable for several months before mixing, as long as it's kept in a cool, dry place.

IVYrx’s Top Tip: If your compounded semaglutide appears cloudy, discolored, or has an unusual odor, do not use it—it may have degraded or become contaminated.

Storing Compounded Semaglutide Properly

Proper storage is crucial to maintaining the potency and effectiveness of compounded semaglutide. Even minor temperature fluctuations or improper handling can cause the medication to degrade, reducing its ability to support weight loss and blood sugar control. Follow these best practices to ensure it stays safe and effective.

Refrigeration Best Practices

• Keep compounded semaglutide stored at 36-46°F (2-8°C) in the refrigerator. Avoid placing it in the freezer, as freezing damages the medication.
• Store vials or pre-filled syringes on a middle shelf, not in the fridge door—this prevents temperature fluctuations when opening and closing the fridge.
• Keep the vial or syringe in its original packaging to protect it from light exposure.
• Avoid storing it near fridge vents, as excessive cold can affect stability.
  ‍

Travel & Short-Term Storage

• If you need to transport your semaglutide, use an insulated travel case with ice packs to maintain proper temperature.
• Compounded semaglutide can remain stable at room temperature (below 86°F / 30°C) for up to 24 hours, but refrigeration is always preferred.
• Never leave semaglutide in a hot car, direct sunlight, or near heat sources like stoves or radiators.
  ‍

Handling & Usage Tips

• Always wash your hands before handling the vial or syringe to prevent contamination.
• Wipe the vial’s rubber stopper with an alcohol swab before inserting a needle.
• If using a multi-dose vial, never reinsert a used needle, as this can introduce bacteria.
• Check for signs of spoilage, such as discoloration, cloudiness, or an unusual odor—if you notice any changes, discard the medication immediately.

IVYrx’s Top Tip: If you’re unsure whether your semaglutide is still effective, consult your pharmacist or healthcare provider before taking a dose.

Safety Tips for Compounded Semaglutide Intake

Proper intake of compounded semaglutide ensures it works effectively while minimizing potential side effects. Follow these best practices:

‍

IVYrx’s Top Tip: Set a weekly reminder to take your semaglutide dose on time—consistency is key for the best results.

Risk of taking expired compounded semaglutide

Using expired compounded semaglutide can lead to several potential risks, including:

• Reduced effectiveness – Expired medication may not work as intended, leading to stalled weight loss progress or poor blood sugar control.
• Increased side effects – Degraded compounds can cause unexpected reactions, including nausea, dizziness, or digestive issues.
• Higher risk of contamination – Bacteria or mold can develop in expired liquid formulations, potentially leading to infections.
• Wasted doses – If potency is compromised, you may unknowingly be using an ineffective medication, delaying your results.

Always check expiration dates and dispose of any questionable medication. If you need a reliable source for high-quality compounded semaglutide, IVY RX offers pharmacy-grade formulations to support your journey.
