What’s Really in the Vial? How to Verify GLP-1s, NAD+, Glutathione and Other Compounded Prescriptions
For compounded meds and wellness injections, know what you're receiving, who prescribed it, which pharmacy prepared it, and what comes next

A vial can look perfectly legitimate and still leave important questions unanswered.
What exactly is in it? Is the medication compounded or FDA-approved? Who prescribed it? Which pharmacy prepared it? What concentration is being used? And who is responsible for monitoring the patient after the first dose?
Those questions matter for compounded GLP-1 medications, but they also apply to prescription wellness treatments such as NAD+, glutathione and other injectable preparations.
Compounded medications can serve an important role when a patient has a clinical need that cannot be met by an FDA-approved drug. But the FDA emphasizes an important distinction: compounded drugs themselves are not FDA-approved, which means the agency does not review each compounded product for safety, effectiveness or quality before it reaches a patient. Poor compounding practices can also create risks involving contamination, incorrect strength, purity or quality.
For patients in New Tampa, Lutz, Land O’ Lakes and Temple Terrace, knowing how to verify a prescription can be just as important as knowing what the treatment is supposed to do.

What should actually be on the medication label?
Patients should know more than the name of the treatment they purchased.
Before using a prescription or compounded injectable, confirm the medication name, concentration, dosing instructions and dispensing pharmacy. The provider should also be able to explain why that particular medication or concentration was selected.
If you were expecting semaglutide, for example, you should understand whether you are receiving an FDA-approved product or a compounded version.
The same principle applies to NAD+, glutathione or another wellness injection.
The treatment name on a website is not enough. Patients should know what is actually in the vial they receive.
Why does the pharmacy matter so much?
Compounding involves preparing medication for a specific medical purpose rather than simply dispensing a mass-manufactured finished product.
That places significant importance on the pharmacy’s sourcing, preparation practices and quality controls.
The FDA warns that poor compounding practices can lead to products that are contaminated or that do not contain the strength, quality or purity patients expect.
That concern becomes even more important when the medication is injected rather than taken by mouth.
Patients should be able to ask their medical provider for the pharmacy’s name and verify that it is appropriately licensed.
If no one can clearly identify where a prescription came from, that is a reason to ask more questions before using it.
Why has injectable glutathione received extra attention?
Glutathione offers one of the clearest recent examples of why ingredient sourcing matters.
On August 27, 2026, the FDA warned compounding pharmacies not to use dietary-supplement-grade glutathione in injectable medications after receiving reports involving at least 30 patients who experienced adverse events.
The FDA said ingredients intended for dietary supplements can contain impurities or contaminants that are not appropriate for injection. Reported reactions included fever, chills, pain, dizziness and other symptoms consistent with endotoxin exposure.
The lesson is broader than glutathione itself.
An ingredient may sound familiar or be commonly sold as a supplement, but that does not automatically mean every version of that ingredient is suitable for an injectable prescription.
What about NAD+?
NAD+ is another wellness treatment that has become increasingly common in IV and injectable programs.
Refresh - Aesthetics & Wellness in Tampa currently offers NAD+ through both IV infusions and intramuscular injection programs. Refresh states that its NAD+ is compounded through licensed pharmacies and administered by trained medical professionals, with protocols tailored to the individual patient.
That sourcing information matters.
Patients considering NAD+ should ask:
- What pharmacy prepared it?
- What dose and concentration am I receiving?
- How will it be administered?
- Who determined that dose?
- Who monitors me during and after treatment?
- What should I do if I experience a reaction?
The same questions should apply whether the treatment is being marketed for energy, wellness, recovery or another purpose.

What should patients verify with a GLP-1 prescription?
GLP-1 medications deserve the same level of scrutiny.
Refresh’s Tampa GLP-1 program currently uses semaglutide and tirzepatide and states that patients first receive a medical evaluation, lab work and health-history review to determine whether either medication is appropriate. The starting dose and titration schedule are then based on the individual patient.
Before beginning a GLP-1 program, patients should understand:
- The exact medication being prescribed
- Whether it is FDA-approved or compounded
- The pharmacy dispensing or preparing it
- The concentration and prescribed dose
- How frequently the dose may change
- Who will manage side effects
- How follow-up will be handled
A legitimate program should not treat every patient as though the same vial and same dose are appropriate.
Why does concentration matter?
With compounded medications, patients should not assume that every vial contains the same concentration.
Two vials may contain the same active ingredient while requiring different volumes to deliver the prescribed dose.
That is one reason a patient should follow the specific instructions attached to their own prescription rather than copying a friend's dose, an old prescription or instructions found online.
The prescribing provider should be able to explain both the prescribed dose and how much medication the patient is expected to administer.
If that explanation is unclear, patients should ask before injecting anything.
What is the difference between a pharmacy and a provider?
They play different roles.
The medical provider evaluates the patient, determines whether a prescription is appropriate and establishes the treatment plan.
The pharmacy prepares or dispenses the prescribed medication according to the prescription and applicable pharmacy standards.
A safe process depends on both sides working correctly.
A properly licensed pharmacy does not replace the need for an appropriate medical evaluation, and seeing a licensed provider does not eliminate the importance of knowing where the medication itself came from.
Should there be a medical evaluation before wellness prescriptions?
Yes, when prescription medication is involved.
The level of evaluation will vary depending on the treatment, but patients should expect their health history, medications and relevant medical conditions to be reviewed.
For GLP-1 treatment at Refresh in Tampa, the practice states that every program begins with a medical evaluation, laboratory testing and review of health history before determining whether treatment is appropriate.
Refresh also describes its Tampa NAD+ programs as personalized according to factors including the patient's health status and individual goals.
Medical oversight should continue after treatment begins, especially when dosing changes or a patient experiences side effects.
What about glutathione and other wellness injections?
Refresh's Tampa office lists several injectable wellness options, including glutathione, amino injections, B-complex, biotin, minerals, Tri-Immune, vitamin C, Bio Boost+ and NAD+.
That variety is exactly why patients should avoid treating all wellness injections as interchangeable.
Each ingredient has a different purpose, dose, route of administration and potential risk profile.
Patients should know exactly what they are receiving rather than simply asking for a generic “wellness shot.”
What is LegitScript certification?
LegitScript certification can serve as an additional check when patients are evaluating healthcare businesses that advertise or operate online.
LegitScript says its Healthcare Merchant Certification applies to businesses involved with telemedicine, online prescription services, pharmacies and medical spas. Its standards include compliance with applicable laws, verification of healthcare practitioner licenses and requirements related to valid prescriptions.
Certification should not replace basic verification.
Patients should still confirm the actual provider and pharmacy involved in their care.
Think of LegitScript as one more layer, not the only layer.
What should you verify before using the vial?
Before taking home or using a compounded GLP-1, NAD+, glutathione or another prescription product, patients can run through a simple checklist:
- What is the exact medication?
Know the name and active ingredient. - Is it FDA-approved or compounded?
Those terms do not mean the same thing. - What concentration is in the vial?
Do not assume it matches another prescription. - Who prescribed it?
Know the provider's name and credentials. - What pharmacy made or dispensed it?
Get the full pharmacy name. - Can the pharmacy be verified?
Check the applicable state pharmacy license. - How should it be stored?
Some prescriptions have specific refrigeration or handling requirements. - Who handles questions or side effects?
There should be a clear point of contact. - When is the next follow-up?
Prescription wellness care should not end when the vial leaves the office. - Is there an additional compliance credential?
LegitScript certification can provide another point of verification for applicable healthcare businesses, but it should complement—not replace—license and pharmacy checks.
The Halloween version of the advice is simple: the scariest part of a prescription should not be wondering what is actually inside the vial.
