Peptide therapy for beginners: 10 things to know before your first consultation

Before a first peptide consultation, the most useful thing to know is that "peptide" covers everything from FDA-approved medicines like insulin and semaglutide to unapproved compounds with nothing but animal studies behind them. Once you can tell which kind is being discussed, almost every other question gets easier: what the evidence is, whether it is legal to prescribe, what it costs, and whether it is worth it for you.

These are the 10 things we most often find ourselves explaining to people new to this area. None of them requires a science background, and knowing them will help you get far more out of a first visit, with us or with anyone else.

1. "Peptide" is a chemistry word, not a quality rating

A peptide is a short chain of amino acids. Some peptides are among the best-studied drugs in medicine: insulin, the GLP-1 medicines used for diabetes and weight management, and several hormone treatments. Others, including many discussed in podcasts and on social media, have never completed human trials. Calling something a peptide tells you its structure, not whether it works or is safe. Our list of FDA-approved peptide medicines shows what is on the approved side of the line.

2. Compounded does not mean approved

Many peptides offered by clinics are compounded, meaning a licensed pharmacy prepares them for an individual patient with a prescription. Compounding has a legitimate role, but compounded drugs are not FDA-approved. No regulator has reviewed their safety, effectiveness or dose for the use being described. That is not automatically a reason to refuse one, but you should know it, and any provider should say it plainly.

3. Legal status changes, sometimes quickly

Whether a pharmacy may compound a given peptide depends on FDA's bulk substance lists and categories, and those have moved a lot in 2026. In July, an FDA advisory committee voted to recommend six peptides, including BPC-157 and TB-500, for the list 503A pharmacies may compound from. That vote was non-binding, and rulemaking would be needed before anything changes. Our regulatory status guide explains the framework, and a provider should be able to tell you where any specific peptide stands on the day you ask.

4. Most of the evidence is from animals or small studies

For many popular peptides, the research consists of rodent experiments and a handful of small, short human studies, often without a control group. That does not prove a peptide is useless. It means nobody knows how well it works in people, at what dose, or what it does over years. Be skeptical of any source that quotes animal results as if they were human outcomes. Our guide to reading peptide evidence shows what to look for.

5. A good consultation starts with you, not a menu

If the first thing you see is a list of "protocols" and packages, be cautious. A clinical visit should start with what you are hoping to change, your medical history, your medications and what you have already tried. For many goals, such as energy, recovery, sleep or body composition, there are causes worth ruling out first, including thyroid problems, low testosterone, sleep apnea, iron deficiency and blood sugar problems. Sometimes an approved medication or a non-drug approach is a better fit. We walk through a typical visit in how a peptide telehealth consultation works.

6. Expect screening questions and probably labs

Some people should not use certain peptides at all, including those who are pregnant, breastfeeding or trying to conceive, people with active cancer or a history of it, and in some cases people with diabetes, heart failure or pituitary disease. Tested athletes face anti-doping rules regardless of a prescription. Baseline labs, such as a metabolic panel, blood sugar markers and, for growth hormone peptides, IGF-1, are common. That is a sign of care, not bureaucracy.

7. Most peptides are injections, and you will be shown how

Most therapeutic peptides are injected just under the skin with a small needle, because many are broken down in the gut if swallowed. Some come as nasal sprays, creams or oral forms, each with its own evidence questions. If an injectable is prescribed, you should be shown the technique, how to rotate sites, how to store the medication, and how to dispose of needles. Some products arrive as powder that must be mixed first, and the instructions for that should come from the pharmacy.

8. Side effects and follow-up should be discussed before you start

Common side effects include injection-site redness, headache, flushing, nausea and, with growth hormone peptides, fluid retention and changes in blood sugar. Before you start, you should know which symptoms mean call the same day, which mean seek emergency care, and when your first follow-up is. Ongoing prescribing should involve check-ins and, where relevant, repeat labs.

9. Cost is usually out of pocket, so ask for the full picture

Insurance rarely covers unapproved or compounded wellness peptides. Ask what the consultation costs, what the medication costs per month, what labs cost, how often follow-up visits happen and whether they are charged separately, and what shipping adds. Our peptide therapy cost breakdown sets out the pieces, and some costs may be eligible for HSA or FSA funds depending on your plan.

10. Telehealth has rules, and limits

A telehealth clinician can generally treat you only if you are physically located in a state where they are licensed at the time of the visit. Aone serves patients in Michigan, Illinois and California. Some problems are better assessed in person, such as an injury that needs examining or imaging, and a good telehealth practice will tell you when that is the case. No consultation, with us or anyone else, should promise a prescription before a clinician has reviewed your history.

What to bring to your first visit

• A clear sentence about what you hope to change and why now.
• A list of all medications, supplements and anything bought online, including past peptides.
• Recent lab results and relevant diagnoses.
• Your personal and family history of cancer, heart disease and diabetes.
• Whether you compete in tested sport or serve in the military.
• Your budget, so the conversation can be realistic.

If you would like to start that conversation, our peptide therapy page explains how we work, and you can book a consultation when you are ready.

Questions patients ask us

What is peptide therapy?

Peptide therapy means using a medication made of a short chain of amino acids. Some are FDA-approved drugs with large trials behind them, such as insulin and GLP-1 medicines. Many offered by wellness clinics are compounded or unapproved and have mostly animal or small human studies. The term describes the chemistry, not whether a given product works or is safe, so it is worth asking which kind is being proposed.

Are the peptides clinics offer FDA-approved?

Some are, many are not. Approved peptide drugs exist for specific conditions, but most wellness peptides, including BPC-157, TB-500, CJC-1295 and ipamorelin, are not FDA-approved for any use. Compounded versions of any peptide are not FDA-approved either, even when prepared by a licensed pharmacy. Ask any provider to state plainly whether what they propose is approved, and for what indication.

Do I need blood work before starting peptides?

Often, yes. Depending on the peptide and your history, a clinician may want a metabolic panel, blood sugar markers such as A1c, and IGF-1 for growth hormone peptides, along with tests that rule out other causes of your symptoms. Labs help decide whether a peptide is appropriate at all and give a baseline for monitoring if one is prescribed.

Will I definitely get a prescription after a consultation?

No, and you should be wary of any service that implies you will. A prescription depends on your history, screening, labs and whether a peptide is a reasonable and lawful option for your goal. Many appropriate consultations end with a different plan, such as an approved medication, further testing, a referral or lifestyle changes.

Are peptide injections painful?

Most people describe subcutaneous peptide injections as a brief pinch or sting. The needles are small and the medication goes into the fat layer just under the skin. Stinging can be worse if the medication is cold or the alcohol swab is still wet. Your prescriber or pharmacy should show you the technique and how to rotate sites before your first dose.

Does insurance cover peptide therapy?

Usually not for compounded or unapproved wellness peptides. Insurance may cover some FDA-approved peptide drugs for their approved uses, subject to the plan. Some consultation, lab or medication costs may be eligible for HSA or FSA funds depending on your plan rules. Ask for the full monthly cost, including labs and follow-up, before you commit.

How long does it take for peptides to work?

There is no reliable answer for most wellness peptides, because controlled human trials that would establish a timeline have not been done. Online timelines are mostly anecdotal. For approved peptide drugs, the label and trials describe expected timing. A clinician should set realistic expectations and a point at which you will review whether a treatment is doing anything.

Can I do a peptide consultation by telehealth?

Often, yes. Much of a peptide evaluation, including history, goals, medication review and lab interpretation, works well by video. You generally need to be physically located in a state where the clinician is licensed at the time of the visit. Some problems, such as an injury that needs examining or imaging, are better assessed in person, and a good practice will say so.

Is it safe to buy peptides online instead?

Products sold online as research use only are not medicines. Their identity, strength, purity and sterility are not verified, and no prescriber is responsible for your safety. Independent testing has repeatedly found contents that do not match the label. Injecting a non-sterile product also carries a real infection risk. Prescription peptides dispensed by a licensed pharmacy are a different category.

What should I bring to my first peptide consultation?

Bring a clear statement of your goal, a full list of medications and supplements including anything bought online, recent lab results, and your personal and family history of cancer, heart disease and diabetes. Mention if you are pregnant, planning a pregnancy, breastfeeding, compete in tested sport or serve in the military, since each changes what is appropriate.
