Why We Only Prescribe FDA-Approved Weight Loss Medication
There is a lot of noise about weight loss drugs right now, including some being sold before they are approved for use at all. Here is where Renew MedSpa stands, and why.
The science of medical weight loss is moving faster than at any point in my career, and I love that. GLP-1 medications have genuinely changed lives, including for patients in our own weight loss program. But fast-moving science attracts a fast-moving marketplace, and lately that marketplace has crossed a line that matters: national reporting in 2026 identified dozens of clinics and more than a hundred websites selling weight loss drugs that have not been approved by the FDA, some labeled “for research use only” while being sold with dosing instructions for people to inject.
Patients ask me about these drugs, and I understand why. The early trial numbers on some investigational medications look remarkable, and when something promising exists, waiting feels unfair. So I want to be completely clear about our standard, and honest about the reasoning behind it.
If a medication is not FDA approved, we do not prescribe it. No exceptions, no matter how promising the headlines.
What FDA approval actually protects you from
It is easy to hear “FDA approval” as paperwork, a government stamp that slows good medicine down. Having spent my career in medical aesthetics, I see it differently. Approval is the difference between a promising molecule and a medicine, and it protects you on three levels most people never think about.
The evidence level. Approval means the full clinical trial program is complete and independently reviewed: not just “did people lose weight,” but long-term safety, appropriate dosing, drug interactions, side effects, and which patients should and should not take it. Early trial results, however exciting, answer only the first question.
The manufacturing level. An approved medication comes from regulated manufacturing with verified purity, accurate dosing in every pen and vial, and a controlled supply chain. An unapproved product sold online might contain the wrong concentration, contaminants, or something else entirely, and there is no system checking. This is not hypothetical: the FDA has published detailed warnings about unapproved GLP-1 products, and US poison control centers reported a surge in exposures to one investigational weight loss drug in early 2026.
The accountability level. Approved medications live inside a monitoring system: adverse events get reported, prescribing gets refined, and problems surface. Products sold “for research purposes only” live outside all of it, which is precisely why they are labeled that way, the label is a legal shield for the seller, not a safety measure for you.
About retatrutide, since you may be hearing that name
The investigational drug generating the most buzz right now is retatrutide, a “triple agonist” that works on three hormone receptors at once. Its phase 3 trial results are genuinely impressive, with average weight loss well beyond current medications. I understand completely why people are excited. I am too.
And we still will not prescribe it, because it is not approved. As of this writing, retatrutide has not even been submitted to the FDA, with submission expected late in 2026 and availability likely years away. It cannot legally be compounded, because compounding is only permitted for components of FDA-approved drugs. That means every vial being sold today comes from outside the legitimate pharmaceutical supply chain, and no one can verify exactly what is in it, because no regulated system is checking.
If retatrutide earns approval, we will evaluate it the same way we evaluated Zepbound: carefully, and then honestly. Until then, the only legitimate path to it is a clinical trial.
A promising drug and an approved drug are not the same thing, and the gap between them is exactly where patients get hurt. I would rather lose a sale than gamble with what goes into your body. That is not caution for its own sake; it is the whole job.
What we do offer, and how it works
Our medical weight loss program is built on Zepbound, an FDA-approved medication with completed trials behind it: in clinical trials, participants on the highest dose lost an average of about 20% of their body weight. In our program, average loss runs 1 to 3 pounds per week, and individual results vary.
Just as important as the medication is the structure around it. You are evaluated by a licensed medical provider before anything is prescribed. Your medication is prescribed through LillyDirect, Eli Lilly’s own pharmacy service, and arrives as the solution form with syringes included in every order, not from a website with a research-use disclaimer. And you check in with us as you go, with provider review before refills, so your dose, your side effects, and your progress are actually being watched by people accountable for your care. That is what “medically supervised” means when it is real.
How to vet any weight loss provider, including us
Wherever you go, and I mean that, even if it is not Renew MedSpa, four questions will tell you nearly everything about whether a weight loss program is safe:
- Is the medication FDA approved? Ask by name, and look it up yourself. If the answer involves “it works just as well” or “the trials are basically done,” that is a no.
- Where does the medication come from? The right answer is a licensed pharmacy. Walk away from anything labeled “for research use only” or “not for human consumption,” those words mean exactly what they say.
- Who evaluates you first? A licensed provider should review your health history before prescribing, not a checkout page.
- Who monitors you after? Weight loss medication needs dose management and side effect support over months. If the plan ends at the sale, it was a sale, not care.
Any legitimate provider will welcome these questions. The ones who get defensive have answered them for you.
Questions we hear about this
No. Retatrutide is investigational and not FDA approved, so we do not offer it, and we would be honest with you about any provider who does. If it earns approval in the coming years, we will evaluate it carefully and let our patients know where we land. In the meantime, our program is built on FDA-approved Zepbound, which has delivered excellent results for our patients.
Compounding has a legitimate place in medicine, and the rules around it are actually a good example of how the system protects you. During the national GLP-1 shortage, the FDA permitted compounding pharmacies to prepare copies of the approved medication, and our program used that pathway while it was authorized. When the shortage officially ended, so did that permission, and we returned to brand medication right along with the rules. Today our program uses brand Zepbound prescribed through LillyDirect, so what is in the vial is exactly what the label says. What was never permitted, shortage or no shortage, is compounding a drug that has never been approved at all.
A medical evaluation by a licensed provider before anything is prescribed, FDA-approved Zepbound prescribed through LillyDirect with syringes included in every order, and ongoing check-ins with provider review before refills so your dose and side effects are managed as you lose. The details are on our weight loss program page, and a consultation is complimentary.
It depends entirely on the source. A telehealth service prescribing FDA-approved medication through licensed pharmacies after a real medical evaluation can be legitimate. A website selling vials labeled for research use, or offering drugs that are not approved anywhere, is not, no matter how professional the site looks. The four questions above apply online exactly as they do in person.
When a new medication earns FDA approval, we will evaluate it carefully and decide whether it makes sense for our clinic and our patients. We are not against new medicine; we are against skipping the part that makes it medicine. Approval is where our evaluation begins, not where it ends.
