The rules behind clinic compounding, quoted from the source.

Explainers for physicians, clinic operators and telehealth teams on how compounding regulation is actually written — verbatim rule text, primary-source citations, and an honest account of what each page could not establish.

Definitions

503A vs 503B

Two different statutory bargains. A 503A pharmacy is exempt from current good manufacturing practice and pays for it with the patient-specific prescription requirement; a 503B outsourcing facility does the reverse.

Compliance

Office-use compounding by state

Whether a clinic may stock compounded medications, compared across every state reviewed. The answers range from outright prohibition to a non-sterile-only permission with a mandatory label legend.

Regulatory explainer

What actually happened to peptides in 2026

Three separate events have been reported as one story: a set of withdrawn nominations, a consultation that has not happened, and a rulemaking that is not final. Only one kind of event changes a list, and none of these did.

Status tracker

Compounding status tracker

Which federal pathway applies to each substance under section 503A and, separately, under section 503B — every row dated to the day its FDA source was read.

Glossary

The terms, and who decides them

Office use, 503A, 503B, beyond-use date, cGMP, non-resident licence and the USP chapters — each defined from the rule that defines it, and each with the body that actually decides whether it binds anyone. It is almost never the one whose name is on the term.

Workflow

How to place an office-use order

What an office-use order carries, what the supplier is required to ask you for, and which answers from a supplier should end the conversation.

Data

Reference tables, with their retrieval dates

Every board of pharmacy and its licence-lookup portal, and where FDA-registered outsourcing facilities are. Each table carries the date its source was read and states what it cannot tell you.

By practice type

What blocks your kind of practice

Med spas, telehealth operators, hormone and weight-management clinics, nurse-practitioner-owned practices and solo prescribers each hit a different binding constraint. Each page leads with the one that is not the others’.

Ordering workflow

How clinics order compounded medications

The whole sequence, from opening an account to what a pharmacy verifies about a prescriber, what documents it asks for, which orders can travel out of an EMR, and what changes the moment a second state is involved.

Comparisons

Two things wearing one name

A prescription delivered to your office is not office stock, a compounded preparation is not a generic, and a registered outsourcing facility is not a drug manufacturer. Each page names the fact that separates the pair.

Operator Q&A

The questions operators actually ask

Whether office use is legal, whether a med spa may hold stock, what a nurse practitioner may order, and what changes across a state line — each with the rule that decides it.

State rules

Reviewed 2026-08-28. Each page quotes the governing rule verbatim.

Ordering through licensed pharmacies

USPeptideRx connects physicians and clinics to licensed 503A compounding pharmacies and FDA-registered 503B outsourcing facilities — patient-specific prescriptions or office stock, on one account.
