Curious about peptides?
Physician-Led Peptide Therapy Consultations
Maybe you heard about peptides from a friend, a podcast or a coach while looking into recovery, sleep, energy, body composition or healthy aging. Bring your questions. We'll talk through what you're hoping to address, explain your options in plain language and help you decide what makes sense for you, including when peptides aren't the right fit. Visits are online, so you can meet with us from home in Chicago or anywhere we're licensed.
Led by Christian Badillo, MD, board certified in Emergency Medicine, with an Advanced Peptide Therapy Certification from the American Academy of Anti-Aging Medicine (A4M).
Our approach
A longevity practice, not a peptide clinic
Peptides are one tool we may use inside a complete, physician-guided plan. They aren't a menu, a package or a shortcut. Before we recommend anything, we look at your goals, your history and, when it helps, your labs.
| What's common elsewhere | How we work |
|---|---|
| Peptide menus and packages | A plan built after a medical evaluation |
| Online "research-use-only" peptides | Licensed, inspected pharmacies only |
| Starting without a health history or labs | Your history reviewed first, labs when they'll change the plan |
| Advice from influencers and online forums | Oversight by a board-certified physician with advanced peptide training |
| No follow-up after the sale | Monitoring and follow-up built in |
The basics
What are peptides?
Peptides are short chains of amino acids, the same building blocks that make up proteins. Your body makes many of its own, and they act as signals that help regulate processes such as metabolism, appetite and healing. Some peptides are FDA-approved medications for specific conditions. Others are prepared by compounding pharmacies for individual patients. Each one works differently, and the research behind them ranges from well studied to early.
Heard about a specific peptide? Bring the name to your visit. We'll talk through what it's used for, how much we actually know about it and whether it's relevant to your goals.
Goals
What patients ask us about
Most people come to us with a goal, not a peptide name. Common ones include:
- Recovery from training or injury
- Sleep quality
- Energy and focus
- Body composition and metabolic health
- Skin, hair and healthy aging
- Gut health
- Sexual health and libido
Peptides may or may not be part of the answer. Sometimes the better first step is a lab finding, a sleep evaluation, a hormone issue or a change in routine. We'll tell you which.
No menu
Why you won't find a peptide menu here
The rules about which peptides pharmacies may prepare change often. A list we post today could be out of date next month. Instead, we discuss specific options during your visit, based on your goals, your health, current regulations and what the research supports.
Costs work the same way. They depend on what your plan includes, so we go over every cost with you before anything is ordered.
Safety
Peptide safety and sourcing come first
Licensed pharmacies only
We prescribe only through licensed, carefully vetted pharmacies, never "research-use-only" products sold online.
A real evaluation first
We review your health history, medications and goals before recommending anything, and order labs when they'd change the plan.
Honest about the evidence
We'll tell you what's well studied, what's early and what's still unknown.
Follow-up built in
If you start a peptide, you'll have a plan for check-ins, side effects to watch for and when to stop.
Not right for everyone
Pregnancy, breastfeeding, a current or past cancer and some other medical conditions can rule out certain options. We'll go over this with you.

FAQ
Questions patients ask us
Can I ask about a specific peptide?
Yes. Bring the name or tell us where you heard about it. We'll explain what it's used for, what the research shows and whether it's worth discussing for you.
Is peptide therapy safe?
It depends on the peptide, the dose, where it comes from and your health. That's why we start with an evaluation, prescribe only through licensed pharmacies and follow up while you're on treatment.
Are peptides FDA-approved?
Some peptide medications are FDA-approved for specific uses. Compounded medications, including many peptides, are not FDA-approved. Compounding lets a licensed pharmacy prepare a medication for an individual patient, which can mean access to options not sold at retail pharmacies, dosing tailored to you and formulas without certain preservatives or allergens. We work only with licensed, carefully vetted pharmacies, and we'll explain what type of medication we're discussing and why.
Where do your peptides come from?
Licensed, inspected pharmacies that we vet carefully. We never use "research-use-only" products, which aren't made for human use.
I'm already using peptides. Can you help?
Yes. Bring what you're using and where it came from. We'll review it, check whether it fits your goals and health and tell you honestly if we'd recommend a change.
Are weight-loss medications part of peptide therapy?
Some weight-management medications, such as GLP-1s, are peptides. When they're appropriate, they're part of a complete metabolic plan with labs and follow-up, not a stand-alone refill service.
Do I need labs first?
It depends on your goals and history. Bring any recent results, and we'll let you know if more testing would help. Sometimes labs point to a better first step. See our Lab Testing Menu
Do I need a membership?
No. Membership is optional. Compare plans
What does it cost?
It depends on what your plan includes. We go over every cost before anything is ordered. Current fees are listed in our Our Process handout.
