MORE THAN A VENDOR
A supply partner.
For the long run.
There is a difference between buying a product and building a relationship with a supplier who understands your business.
As your practice grows, purchasing requirements change. Volume increases. New categories become relevant. Inventory becomes more important. Our goal is to be the supplier you can call for product, pricing, information, or a straight answer.

ONE 503A PHARMACY
Direct fulfillment.
No platform in between.
RX503 fulfills from a single 503A compounding pharmacy. A prescription is prepared for one patient and dispensed for home use. The practice works with the pharmacy directly.
No middleman markup
Pricing comes from the pharmacy. A platform does not take a cut in between.
No monthly fees
No platform subscription between the practice and the pharmacy.
No setup costs
Catalog access and direct pricing, without a setup charge.
No hidden charges
The price you review is the price. No fees added on later.
WHAT 503A MEANS
A pharmacy for one patient at a time.
A 503A compounding pharmacy is a traditional pharmacy overseen by the state board of pharmacy. It prepares a medication for an individual patient after a licensed provider writes a prescription.
Patient-specific
Compounded only after a valid prescription for that patient. Not produced as a large batch in advance.
State oversight
Primarily overseen by the state board of pharmacy.
USP standards
Follows USP <795> for non-sterile preparations, USP <797> for sterile preparations, and USP <800> for hazardous materials.
Home use
Dispensed for that patient's use at home. Not sold in bulk as clinic or office stock.
DIRECT PRICING FOR YOUR PRACTICE
Margins matter.
So does your supplier.
RX503 offers direct pricing for clinics, med spas, wellness practices, and other qualified purchasers. No middleman markups, setup costs, monthly fees, or hidden charges.
Clear costs. More room to grow. As your purchasing volume increases, talk with our team about available volume pricing.
