01. Specialized expertise
We focus on peptides, GLP-1 therapies, hormones and specialty formulations, prepared by pharmacists who work with them every day. When the margin for error is small, depth beats breadth.
InterX is a 503A compounding pharmacy for providers and patients. We compound peptides, hormones and specialty formulations to the exact prescription, test every batch for identity, potency and sterility, and ship it with the certificate of analysis to prove it.
Why InterX
Most compounded medications arrive with nothing but a label, and the provider has to take the strength, the purity and the sterility on faith. We built InterX to remove that leap. Every order is made to the exact prescription, tested before it ships, and documented so the quality is something you can read, not something you hope for.
Every preparation is compounded to the prescribed strength and form, never a one-size dose. The formula on the script is the formula in the vial.
Each batch is tested for identity, potency and sterility, then released with its certificate of analysis. You see the result, not just the label.
Fast, tracked fulfillment and pharmacists you can actually reach, so prescribing is one less thing to worry about.
The case for compounding
Most pharmacies dispense what a manufacturer made: a fixed strength, a fixed form, produced in mass lots. That works, until it doesn’t. A patient needs a dose that was never commercialized. A widely used medication goes into shortage. A protocol calls for a strength, a combination or a delivery form the shelf simply doesn’t carry. That gap, between what is manufactured and what a patient actually needs, is where compounding lives.
It has never mattered more. Demand for GLP-1 therapies, peptides and personalized protocols has outrun the supply chain, and providers are left looking for a partner who can prepare exactly what they prescribe, reliably and legally. InterX Pharmacy is that partner. We are a 503A compounding pharmacy in Miami, Florida, and 503A compounding is a legal, regulated pathway for preparing patient-specific preparations, including peptides like Tirzepatide and Retatrutide, against a valid prescription. We operate fully within it, registered with the FDA and licensed by the State of Florida.
But access is only half the work. The other half is trust. When a compounded vial arrives at a clinic, the provider usually has no way to know whether the strength on the label is the strength inside, whether it’s pure, whether it’s sterile. They prescribe on faith. We think that’s the wrong way to run a pharmacy your patients depend on.
So every preparation we make is compounded to the exact formula, tested for identity, potency and sterility, and released with its own certificate of analysis. The COA travels with the order. A provider can see the evidence before a single dose is given, and a patient can fill a prescription knowing exactly what is in the bottle. The proof isn’t a marketing line for us. It’s the product.

How compounding works
Compounding is the preparation of a medication tailored to a specific prescription, strength or form. Here is how an order moves through our facility, and where the proof comes from at each step.
A provider sends the script with the exact compound, strength and form. Patients start from a consultation, and we coordinate the fill with their prescriber.
Pharmacists prepare each order to that formula in our 503A facility, under USP <797> and <800> standards, with weights and steps recorded as they go.
Before anything is released, the batch is tested for identity, potency and sterility, and the certificate of analysis is issued for the lot.
Released orders go out fast, shipped cold-chain and tracked, typically within 48 hours, with the COA and lot record attached.
Quality
Quality is not a final inspection, it is built into every step, from the raw material we accept to the batch we release. Every preparation is tested and documented before it ships, so you never have to take the result on trust.

We focus on peptides, GLP-1 therapies, hormones and specialty formulations, prepared by pharmacists who work with them every day. When the margin for error is small, depth beats breadth.

Strength, form and combination, all to the exact prescription. When the commercial product doesn’t fit the patient, we prepare the one that does, never a one-size dose.

Nothing leaves unproven. Every order is tested for identity, potency and sterility, and ships with the certificate of analysis to back it. The evidence travels with the medication.
