How to Choose a Peptide Therapy Clinic: 7 Questions to Ask Before You Book

The peptide therapy industry has grown from a niche corner of regenerative medicine into a multi-billion dollar market, and patient demand is outpacing regulation. Clinics range from highly credentialed functional medicine practices staffed by board-certified MDs, to telehealth operations with opaque supply chains and no physical location.

The difference matters. Poorly sourced peptides, unlicensed prescribers, and missing documentation have led to adverse events that a simple checklist could have prevented. Below are the seven questions our medical editorial team has identified as non-negotiable before you spend a dollar with any clinic.

A reputable clinic should be able to answer every one of these questions clearly and in writing. If a provider hesitates, deflects, or tells you "trust us," that is a red flag, not reassurance.

Q1: Are your providers licensed in my state?

Peptides prescribed for clinical use must be ordered by a licensed prescriber (an MD, DO, NP, or PA) holding an active license in the state where the patient resides. This is not negotiable. Prescribing across state lines without a valid license violates state medical practice acts and can expose both the provider and patient to significant legal risk.

Ask the clinic to confirm the license number and state of their prescribing provider. Then verify it yourself using your state medical board's public lookup tool. Most boards have this available online at no cost.

• Ask for the prescriber's full name, credential, and license number
• Verify with your state medical board's online lookup
• For telehealth clinics, confirm they hold a license in your specific state
• Be wary of clinics that route prescriptions through a single physician in a single state for all patients

Q2: Do you provide a Certificate of Analysis with every batch?

A Certificate of Analysis (COA) is a third-party laboratory document that confirms the purity, potency, and identity of a peptide compound. It should be issued by an accredited analytical laboratory (not the compounding pharmacy itself) and should accompany every individual batch, not just a generic product line.

If a clinic cannot provide a COA, cannot tell you which lab produced it, or shows you a COA dated more than 6 months ago for a current batch, do not proceed. This is the single most common indicator of substandard sourcing.

The COA should show at minimum: HPLC purity percentage, mass spectrometry confirmation of peptide identity, endotoxin testing results, and the name and accreditation number of the testing laboratory.

Q3: Which compounding pharmacy do you work with?

In the US, peptides prescribed for clinical use must come from an FDA-registered 503A or 503B compounding pharmacy. The distinction matters: 503B outsourcing facilities operate under stricter GMP requirements and are inspected more rigorously than 503A pharmacies, which serve individual patient prescriptions.

Ask for the pharmacy name and verify it on the FDA's database of registered facilities. Some clinics source from multiple pharmacies depending on the compound. That is acceptable, but each source should be verifiable.

• Ask for the compounding pharmacy name and NABP e-profile number
• Verify FDA 503A or 503B registration at FDA.gov/drugs
• Confirm whether your peptide comes from a dedicated lot with its own COA
• Ask whether the clinic uses the same pharmacy for all compounds or varies by product

Q4: Do you offer a physical examination, or is it telehealth only?

Telehealth peptide prescribing is legal and widely practiced, but the quality of telehealth consultations varies enormously. A responsible telehealth prescriber should still conduct a thorough intake, review blood work or relevant labs, document a clinical rationale for prescribing, and follow up.

A clinic that offers to prescribe after a 10-minute intake form with no lab work is not practicing responsibly. At minimum, any clinic, whether physical or virtual, should request recent bloodwork relevant to your requested therapy before issuing a prescription.

Q5: What protocols do you follow, and can I see them in writing?

Responsible clinics operate from written, evidence-based protocols for each peptide they prescribe. These protocols should include dosing ranges, administration frequency, cycle length, contraindications, and monitoring requirements. They should be grounded in peer-reviewed research, not anecdote or community convention.

Ask the clinic to provide the written protocol for your specific peptide before the consultation ends. If they cannot, or will not, that is a significant warning sign.

Q6: How do you handle adverse events or side effects?

Every clinic prescribing pharmacologically active compounds should have a documented adverse event protocol. This includes a direct line to a prescribing provider (not just a patient portal), guidance for patients on when to seek emergency care, and a process for reporting serious adverse events.

Telehealth-only clinics face structural challenges here: if a patient experiences a reaction, they may not be able to reach anyone quickly. Ask specifically: who do I call if I have a serious reaction, and how quickly will a licensed provider respond?

Q7: What are all the costs, and what is included?

Peptide therapy costs vary widely and are rarely straightforward. The consultation fee is typically only the beginning. Patients should ask about the cost of the prescription itself, compounding fees, shipping, monitoring labs, and follow-up appointments.

• Initial consultation fee (often $100-$300)
• Monthly peptide cost (varies significantly by compound and dose)
• Follow-up visit frequency and cost
• Required lab work: who orders it, and who pays for it
• Cancellation and refund policies

The Bottom Line

A reputable clinic will welcome these questions. An unreputable one will not.

The peptide therapy space is maturing, but it still lacks the regulatory clarity patients deserve. Until that changes, due diligence falls on the patient. Use this checklist before every consultation, and do not let enthusiasm for a treatment outpace the verification it requires.
