Medication made for the person taking it
Sometimes the version on the shelf doesn't work. Wrong dose. Impossible to swallow. A dye your body won't tolerate. We're an independent compounding pharmacy off Woodruff Road in Simpsonville, and we make the medication fit the patient.

What goes into every preparation
A cream looks like a cream. You can't tell sourcing, potency, or process by looking at the jar. So here's what goes into ours, and how you can check each one.
We know where our ingredients come from.
We source our bulk active pharmaceutical ingredients through qualified suppliers, including PCCA, a leading supplier to compounding pharmacies. Certificates of analysis and documented chain of custody help us verify what an ingredient is and where it came from before we use it.
We pay to have our own work tested.
We go a step further by randomly selecting finished preparations for independent potency testing. We do it because “we made it correctly” is something a pharmacy says about itself. A third-party assay is something you can actually look at.
We follow applicable standards.
We prepare patient-specific nonsterile medications following applicable USP guidelines and South Carolina pharmacy requirements, with a record for every preparation.
You're welcome to come watch.
If you want to see how your medication gets made, come in and we'll show you. Call ahead so we can time it right. We'd rather you trust what you've seen than what we've written on a page.
Your provider writes the prescription
Compounded medication needs a prescription, same as anything else. If your provider already knows what they want, they can send it straight to us by e-prescribe, fax, or phone.
If they're not sure what's possible, we'll talk to them
This is the part people don't expect. Providers don't always know what a compounding pharmacy can do, and that's reasonable: it isn't taught much. Have them call us, or tell us who they are and we'll reach out. We'll walk through the options with them and they decide.
We prepare it
Most preparations are ready in 48 to 72 hours. Some take longer depending on the compound, and we'll tell you which yours is when we take the order.
You pick it up, or we bring it to you
Curbside pickup at the Woodruff Road location, or free local delivery.
Don't have a prescription yet, or not sure whether compounding is even the answer? Tell us what's going on and we'll tell you whether this is something we can help with.
What we compound
Six areas cover most of what comes through our door. Pick the one that sounds like your situation, or tell us what you need if it isn't here.
Hormone Therapy (BHRT)
Bioidentical estradiol, progesterone, and testosterone, in the form and strength your provider prescribes. Creams, capsules, troches, and suppositories.
For: anyone starting or already on hormone therapy.
Men's Health
Compounded testosterone in several forms, enclomiphene, and other men's hormone preparations.
For: men working with a provider on testosterone or hormone support.
Women's Health
Vulvovaginal preparations, sexual-health formulations, and other women's compounding beyond hormone therapy.
For: women whose needs go past — or sit alongside — hormone therapy.
Pediatric
Preparations made without specified dyes, allergens, or inactive ingredients when prescribed, plus strengths made for a child's actual weight.
For: parents of a kid who won't or can't take the commercial version.
Veterinary
Flavored suspensions, transdermals, and capsules — cats and dogs through to the occasional reptile.
For: pet owners and veterinary practices.
Weight & Metabolic
Non-injectable metabolic support prepared to your provider's prescription.
For: patients working on weight or metabolic health with a provider.
Also compounded here: thyroid · dermatology and topicals · dental · hospice and palliative · sports medicine · nail preparations · flavoring. Don't see it? Ask us . If it's compoundable and your provider prescribes it, there's a good chance we make it.

Mass-produced medicine assumes an average patient
Commercial drug manufacturing is built around the most common case, one strength, one form, one set of inactive ingredients, for millions of people. It works most of the time, which is exactly why it's the default.
But there's a real population it doesn't serve. The child who gags on every tablet. The adult whose commercial dose is twice what their body needs. The patient with a documented dye allergy and no dye-free version on the market. The pet nobody makes a 4-milligram capsule for.
None of those are difficult problems. They're just problems mass manufacturing was never designed to solve.
When a compounding pharmacy is the answer
| The situation | What compounding does about it |
|---|---|
| The commercial dose is wrong for you | We prepare the strength your provider actually wants — including strengths that don't exist commercially. |
| You can't swallow pills | The same medication as a flavored liquid, a cream, a troche that dissolves under the tongue, or a suppository. |
| There's an ingredient you react to | We prepare it without the dye, filler, preservative, gluten, or lactose that's causing the problem. |
| The medication was discontinued | If the active ingredient is still available and it's appropriate, we can often prepare it again. |
| A child won't take it | We flavor it and adjust the form until it's something they'll actually accept. |
| Your pet needs a dose nobody makes | Small-animal doses, flavored to the species. |
| You need several things in one preparation | Where clinically appropriate, we can combine medications into a single cream or capsule your provider specifies. |
What "503A" means
You'll see 503A on this page and in our licensing. It's the section of federal law that covers pharmacies preparing medication for an individual patient with a prescription — which is what we do, and all we do.
Greenhill Pharmacy prepares patient-specific medications pursuant to valid prescriptions. We do not manufacture medications for general distribution. If you've read that compounded medications aren't FDA-approved, that's accurate and it applies to us. FDA approval is a process for mass-manufactured drug products, and a preparation made for one person doesn't go through it. What governs us instead is the South Carolina Board of Pharmacy, applicable USP guidelines and South Carolina pharmacy requirements, and the prescription itself.
