FAQ — Compounding, Peptides & Portal Access | MedClinic Partners

Question 1

What's the difference between 503A and 503B?

Accepted Answer

503A refers to traditional compounding pharmacies that prepare patient-specific medications based on individual prescriptions. 503B refers to FDA-registered outsourcing facilities that produce medications in bulk under cGMP standards — without requiring a per-patient prescription. MedClinic Partners provides access to both channels. See our full 503A vs 503B comparison page for a detailed regulatory breakdown.

Question 2

Do you support all 50 states?

Accepted Answer

Yes. MedClinic Partners ships to all 50 states. Our logistics network is licensed and compliant in every state. Overnight cold-chain delivery is available nationwide via FedEx and UPS.

Question 3

How does onboarding work?

Accepted Answer

For licensed clinics and providers: submit your NPI number through the portal. Verification is instant via the CMS registry. Most providers are active and placing orders the same day. For 503A pharmacies: submit your pharmacy license and DEA registration. Our team verifies credentials typically same business day and assigns a dedicated PharmD account contact.

Question 4

Is this for licensed providers only?

Accepted Answer

Yes. MedClinic Partners is exclusively for licensed medical providers — including clinic owners, physicians, nurse practitioners, and licensed 503A compounding pharmacies. A valid NPI number (for providers) or pharmacy license and DEA registration (for pharmacies) is required. Consumer access is not available.

Question 5

Who can access the MedClinic Partners portal?

Accepted Answer

The portal is available to licensed medical providers — including clinic owners, physicians, nurse practitioners, and licensed pharmacies — who hold a valid NPI number. NPI is verified instantly via the CMS registry. Consumer access is not available.

Question 6

How does NPI verification work?

Accepted Answer

When you register, your NPI number is verified in real time against the CMS National Provider Identifier registry. Verification is typically instant. Once confirmed, your account is activated — usually same day.

Question 7

Are there portal access fees or minimum order requirements?

Accepted Answer

No. MedClinic Partners charges no portal access fees. There are no monthly minimums or setup costs for NPI-verified providers. You pay only for the products you order.

Question 8

How quickly can I place my first order after registering?

Accepted Answer

Most providers are active and placing orders the same day they register. NPI verification is instant. Once your credentials are confirmed, your account contact will walk you through the current formulary and pricing.

Question 9

What is the difference between 503A and 503B compounding?

Accepted Answer

503A refers to traditional compounding pharmacies that prepare patient-specific medications based on individual prescriptions. 503B refers to FDA-registered outsourcing facilities that produce medications in bulk under cGMP standards — without requiring a per-patient prescription. MedClinic Partners provides access to both channels through our licensed network.

Question 10

Do you supply compounded semaglutide and tirzepatide?

Accepted Answer

Yes. MedClinic Partners facilitates access to compounded semaglutide and tirzepatide through our 503A and 503B network for licensed medical providers. All products are USA-manufactured and available with overnight delivery.

Question 11

How does the 503B wholesale buyers club work?

Accepted Answer

Our 503B channel operates as a wholesale buyers club — we pool orders across our provider network to access bulk pricing from FDA-registered 503B outsourcing facilities. There is no per-patient prescription required for 503B orders. Providers and licensed pharmacies receive wholesale group pricing with no portal fees.

Question 12

Are compounded GLP medications FDA-approved?

Accepted Answer

Compounded GLP medications (such as compounded semaglutide and tirzepatide) are prepared by licensed 503A or 503B compounding pharmacies and are not FDA-approved finished drug products. They are legally available when the branded equivalent is on the FDA drug shortage list or when a patient has a documented medical need for a customized formulation. MedClinic Partners supplies compounded versions only, through our licensed compounding pharmacy network.

Question 13

What is a Beyond-Use Date (BUD) and how is it determined?

Accepted Answer

BUD stands for Beyond-Use Date — the date after which a compounded preparation should not be used. BUDs for compounded medications are determined by USP standards and the compounding pharmacy's testing protocols. MedClinic Partners works exclusively with facilities that provide validated BUD documentation, ensuring providers receive medications with appropriate stability data.

Question 14

What peptides are available through the portal?

Accepted Answer

MedClinic Partners offers a growing catalog of USA-manufactured peptides including BPC-157, TB-500, CJC-1295/Ipamorelin, PT-141, Sermorelin, and Epithalon. All are available to NPI-verified providers through the portal. Retatrutide (RETA) is available through our separate IRB program — not through the standard portal.

Question 15

Are peptides available for human use?

Accepted Answer

Research-use-only (RUO) peptides available through the MedClinic Partners portal are intended strictly for laboratory and research purposes. They are not intended for human consumption, therapeutic use, or clinical application. Providers are solely responsible for compliance with all applicable federal, state, and local regulations governing the purchase and use of research-use-only compounds.

Question 16

What is retatrutide and how is it accessed?

Accepted Answer

Retatrutide is available through MedClinic Partners via IRB (Institutional Review Board) study enrollment — a completely separate program from the standard portal. Providers enroll their practice in an IRB-approved research protocol, which allows access to compounded retatrutide under a research use framework. Our team guides providers through the enrollment process. Contact us through the portal to get started.

Question 17

What states do you ship to?

Accepted Answer

MedClinic Partners ships to all 50 states. Our logistics network is licensed and compliant in every state. Overnight cold-chain delivery is available nationwide via FedEx and UPS.

Question 18

How is cold-chain integrity maintained during shipping?

Accepted Answer

All temperature-sensitive products are shipped in validated cold-chain packaging with temperature monitors. Overnight FedEx/UPS delivery is standard. Temperature logs are provided with each shipment. Our logistics team tracks every order from dispatch to delivery.

Question 19

What documentation comes with each shipment?

Accepted Answer

Every shipment includes a Certificate of Analysis (CoA), BUD documentation, cGMP facility certification, FDA facility registration number, and cold-chain temperature log. Extended BUD stability data is available on request.

Question 20

Can 503A pharmacies source 503B products through MedClinic Partners?

Accepted Answer

Yes. Licensed 503A compounding pharmacies can access our 503B outsourcing network for bulk GLP supply and cGMP peptides. No per-patient prescription is required for 503B orders. Submit your pharmacy license and DEA registration to get started — our team verifies credentials typically same business day.

Question 21

Do you offer USA-made cGMP RUO peptides?

Accepted Answer

Yes. USA-manufactured cGMP research-use-only peptides are available on the same platform as 503A/503B compounded GLPs. Licensed clinics and 503A pharmacies access both through a single credentialing process. Available peptides include BPC-157, TB-500, CJC-1295/Ipamorelin, PT-141, Sermorelin, Epithalon, and more.

Question 22

Can licensed 503A pharmacies access 503B bulk supply through MedClinic Partners?

Accepted Answer

Yes. Licensed 503A compounding pharmacies can access our 503B outsourcing network for bulk GLP supply and cGMP peptides. No per-patient prescription is required for 503B orders. Submit your pharmacy license and DEA registration to get started — our team verifies credentials typically same business day.

Question 23

What credentials does a 503A pharmacy need to provide?

Accepted Answer

To access 503B supply, licensed 503A pharmacies provide their state pharmacy license number, DEA registration, and state of operation. Our team verifies credentials and assigns a dedicated PharmD account contact.

Question 24

Is there a separate process for pharmacies vs. clinics?

Accepted Answer

Yes. Clinics and individual providers access the portal using their NPI number. Licensed 503A pharmacies access 503B bulk supply through a separate credentialing process using their pharmacy license and DEA registration. Both channels are available through MedClinic Partners — contact us to determine the right path for your practice.

Question 25

How does MedClinic Partners ensure ongoing compliance?

Accepted Answer

MedClinic Partners provides continuous compliance monitoring for all partner providers. Our team — which includes attorneys with 15+ years of pharma litigation experience and licensed PharmDs — tracks FDA guidance updates, shortage list changes, and state board requirements in real time. All compounding partners are USA-based cGMP-certified facilities.

Question 26

Is MedClinic Partners a pharmacy or a drug manufacturer?

Accepted Answer

No. MedClinic Partners is a facilitation and partner introduction platform. We connect licensed medical providers and pharmacies with vetted, licensed compounding facilities and supply networks. We do not manufacture, dispense, or prescribe medications.

Question 27

What is the IRB program and is it separate from the portal?

Accepted Answer

Yes — the IRB (Institutional Review Board) program is completely independent from the standard portal. It gives qualified providers the opportunity to participate in a wide range of research studies covering various peptides and compounds, including retatrutide. You can participate in both programs, or just one. Contact us for details on IRB enrollment.
