Compounded support for weight and metabolic health
We compound several non-injectable options for weight and metabolic health, including low-dose naltrexone and sublingual preparations, all to your provider's prescription. We don't compound injectables of any kind.
Every prescription reviewed by a pharmacist before anything is dispensed.
Licensed 503A pharmacy in South Carolina — patient-specific preparations, prepared here.
Non-injectable preparations only — no sterile compounding, stated up front.
We work from your provider's prescription — we don't prescribe, and we don't sell programs.
When the standard option isn't the right fit
What gets prescribed most often isn't always what fits the person taking it. Commercial medications come in fixed strengths. When the commercial dose doesn't fit, your provider can prescribe a strength made for you.
And sometimes the right dose is a fraction of what the manufacturer makes — a tenth of a tablet, not a whole one. That's the version a pharmacy has to make from scratch, and it's where compounding does its most useful work.
What we compound
All of these require a prescription from your provider. None of them are injectables.
When a provider determines that a patient prescribed a GLP-1 medication needs a non-injectable form, we can prepare a sublingual preparation to that prescription. Compounded medications are not FDA-approved. FDA has not reviewed this preparation for safety, effectiveness, or quality, and absorption and clinical response may differ from FDA-approved products.
Low-dose naltrexone (LDN)
Capsules or oral liquid, at low strengths that aren't commercially manufactured
Some providers prescribe LDN for metabolic and inflammatory conditions; the research is still developing. Your provider determines whether it's appropriate.
Naltrexone / bupropion combinations
Capsules, at the strength your provider specifies
Prescribed as part of a provider-managed approach to weight and appetite.
Sublingual GLP-1 preparations
Sublingual preparation, when a provider determines a non-injectable form is needed
For patients prescribed a compounded GLP-1 medication. Compounded preparations are not FDA approved, and absorption and clinical response may differ from FDA-approved products. Treatment decisions should be made with the prescribing provider.
Sublingual B-12
Under-the-tongue
For patients whose provider prescribes B-12. Sublingual only. We don't prepare B-12 injections.
On injectables: we don't compound them. No sterile preparations of any kind, including injectable GLP-1 medications. If you're not sure whether something your provider prescribed is something we make, call us.
Why the strength has to be exact
Low doses are where precision matters most
LDN is prescribed at a fraction of the commercially available naltrexone strength, which is the whole reason it has to be compounded. Getting that fraction right is the job, and a pharmacist verifies it before anything is dispensed.
We source and document our ingredients
We use qualified suppliers, including PCCA, and maintain ingredient documentation. See our Compounding page for the full sourcing, testing, and standards process.
Call us first if you're not sure
We can tell you whether what you're considering is something we prepare, before you spend an appointment on it. That's a two-minute phone call.
Your provider writes the prescription
These are prescription medications and the clinical decision is your provider's. If they want to discuss strengths or forms with a pharmacist, we're glad to take that call.
We compound it to the prescription
Typically 48 to 72 hours, depending on the preparation.
Pick it up, or we'll deliver locally
Curbside pickup and local delivery are available.
Don't have a provider managing this yet? Weight changes are sometimes tied to hormones. Our hormone consultation is one place to raise that, and any therapy starts with a licensed provider's evaluation.
Not sure if we make it?
If you're not sure whether what you need is compoundable, that's the call to make. The answer is sometimes a strength nobody manufactures.
