Key Takeaways

• Real semaglutide always requires a prescription, if it's available without one, it's likely fake

• Legitimate semaglutide comes in liquid injection or oral pill form, never as a powder

• Semaglutide salts like semaglutide sodium or semaglutide acetate are not the same as pharmaceutical-grade semaglutide and have not been tested for safety

• If a seller tells you to hide your medication source from your healthcare team, that's a major red flag

• If you believe you've been given counterfeit semaglutide, stop taking it and speak to your healthcare provider

Why Fake Semaglutide Is A Growing Safety Concern

Taking a GLP-1 medication like semaglutide is a major step in your weight-loss journey. It can be anxiety-inducing to start any new medication, especially an injection! 

One worry comes to many people’s minds when they start semaglutide: How do you know that you’re getting the real deal when you purchase semaglutide?

Common Signs of Fake or Unsafe Semaglutide Products

Semaglutide Without a Prescription

Both compounded semaglutide and brand-name semaglutide (Ozempic/Wegovy) are available by prescription only. They always require a doctor or nurse practitioner’s approval to access. Semaglutide is a powerful medication that can make a huge difference in people’s lives, and like many other powerful medications, it requires the supervision of a healthcare provider. 

If someone claims to have semaglutide available without a prescription, it’s very likely to be fake medication, and may be dangerous.

Semaglutide Sold as a Powder or DIY Injection

Legitimate semaglutide is typically available in a liquid form for injection or a pill form to take orally. Semaglutide in a powdered form is either not medication at all, or it is a lower-grade version for use in research. This research-grade powdered semaglutide is not intended for medical treatment. It is not tested to the same standards of quality and safety as pharmaceutical-grade semaglutide.

If you see a powder claiming to be semaglutide, it’s not real prescription-quality medication.

Products Containing Semaglutide Salts

Real pharmaceutical semaglutide is the base form of the medication. This base form has gone through rigorous testing in clinical trials to confirm safety and efficacy. The salt form of semaglutide is different, because the chemical makeup of it includes different elements. Semaglutide sodium and semaglutide acetate are examples of semaglutide salts. These salt forms have not been tested for safety or effectiveness and should not be used. 

If it’s not the base form of semaglutide, it’s not legitimate and may not be safe or effective.

Sellers That Avoid Medical Oversight or Transparency

Your obesity medicine provider is one part of your healthcare team. Other members of that team may include your primary care provider, an endocrinologist (hormone specialist), a dietitian, a mental health provider, a surgeon, or a pharmacist. Collaboration is very important in medical care. If the provider of your semaglutide tells you to keep members of your healthcare team in the dark about the source of your medication, that’s a major red flag! 

If the source of your semaglutide tells you to hide information about where you get the medication, it may be fake semaglutide!

What to do if your Semaglutide is fake

If you believe you’ve been given counterfeit or unsafe semaglutide, do not continue to take the medication. Instead, speak to your healthcare provider about what you’ve been taking, where you got it, and any symptoms you may have experienced. They can help you safely transition to a prescription medication, and they can help you address any potential side effects or health concerns. You can also report counterfeit or unsafe products to the FDA through their MedWatch program. The most important thing is your safety, and there are safe and legitimate options out there for you.

FAQs

Is compounded semaglutide safe?

Compounded semaglutide from reputable pharmacies, prescribed by a doctor or nurse practitioner, can be a safe and effective option. The key is making sure it uses the base form of semaglutide, not a salt form like semaglutide sodium or semaglutide acetate. Mochi Health partners with a network of reputable compounding pharmacies to ensure you have access to safe, effective, individualized weight loss medications.

How can I tell if my semaglutide is fake?

There are several warning signs: it's available without a prescription, it comes in a powder form instead of liquid or oral pill, it contains a salt form like semaglutide sodium or semaglutide acetate instead of base semaglutide, or the seller tells you to hide information from your healthcare team. If any of these apply, it may not be legitimate medication.

What is semaglutide sodium?

Semaglutide sodium is a salt form of semaglutide. The chemical makeup includes different elements than the base form that has gone through rigorous testing in clinical trials.

What should I do if I think my semaglutide is fake?

Do not continue to take the medication. Speak to your healthcare provider about what you've been taking, where you got it, and any symptoms you may have experienced. They can help you safely transition to a prescription medication. You can also report counterfeit or unsafe products to the FDA through their MedWatch program.
