There is a right way to use peptides. There is also a risky way.
Peptides work only when the right person uses the right one at the right time, for the right reason.
You are not looking for random peptides. You are looking for clinical guidance.

|
100% telehealth with physician-supervised care and at-home or local testing options
|
Peptides do not work in isolation.
Your response depends on your whole system.
| What We Evaluate | Why It Matters |
|---|---|
|
Safety Markers
|
Blood counts, liver markers, kidney function, glucose, lipids, inflammation, and medication history help determine clinical fit.
|
|
Mitochondrial Function
|
Peptides that target energy, recovery, or metabolism may work best when mitochondrial stress and cellular energy are evaluated first.
|
|
Hormonal Health
|
Thyroid, cortisol, estrogen, progesterone, testosterone, DHEA, and insulin can influence how your body responds to peptide support.
|
|
Metabolic Health
|
Insulin resistance, glucose instability, body composition, and lipid patterns can affect fat loss, energy, cravings, and recovery.
|
|
Gut Health
|
Gut dysfunction can contribute to inflammation, poor absorption, immune activation, brain fog, and poor treatment response.
|
|
Inflammation
|
Chronic inflammation can interfere with repair, recovery, metabolic function, hormone signaling, and cellular resilience.
|
|
Nutrient Status
|
Deficiencies can limit energy production, tissue repair, immune function, sleep, and recovery.
|
|
Biological Aging
|
TruAge and organ-system data may help identify where your body is aging faster or under greater stress.
|
|
Immune Function
|
Immune imbalance may affect inflammation, tissue repair, reactivity, and long-term resilience.
|
|
Stress & Recovery
|
Sleep, cortisol rhythm, nervous system load, and recovery capacity can determine whether optimization is sustainable.
|
|
Body Composition
|
Lean mass, fat mass, visceral fat, and bone health help guide metabolic and longevity-focused protocols.
|
Your health is not a place for shortcuts.
HFW uses peptide therapy only within a structured clinical framework.
| Our Standard | What It Means |
|---|---|
|
Clinical Intake First
|
We review your health history, medications, goals, prior labs, symptoms, and risk factors before considering therapy.
|
|
Labs Before Protocols
|
We use bloodwork and functional testing to understand your baseline and identify contraindications or missed dysfunction.
|
|
Quality-Focused Sourcing
|
When appropriate, protocols are coordinated through licensed pharmacy partners or regulated channels, not online marketplaces.
|
|
Documentation Review
|
Quality documentation, sterility, purity, endotoxin, and batch-level testing standards are considered when available and applicable.
|
|
No Research-Only Vendors
|
We do not build care around gray-market, research-only, unverified, or patient-purchased products.
|
|
Structured Dosing
|
Dosing, timing, duration, and sequencing are determDosing, timing, duration, and sequencing are determined by the clinical team, not copied from the internet.
ined by the clinical team, not copied from the internet.
|
|
Ongoing Monitoring
|
Symptoms, biomarkers, safety markers, and response patterns guide every adjustment.
|
|
Clinical Restraint
|
Not every patient needs peptides. Not every peptide fits every goal. Not every protocol should continue indefinitely.
|

We review your symptoms, goals, prior peptide experience, and medical history, then talk through whether HFW is the right fit.
Advanced testing and safety labs show whether peptide therapy is appropriate for your biology before anything begins. Kits ship to your door or get coordinated locally.
Your provider reviews the data and builds a personalized peptide-readiness and optimization strategy with clear priorities.
We address the foundation first, gut, hormones, inflammation, and nutrient gaps, so peptides work as intended rather than in isolation.
Your protocol begins with physician-supervised dosing, pharmacy coordination when appropriate, supplements, and ongoing monitoring.
Quarterly labs, response tracking, and safety monitoring help you protect your progress and adjust the protocol as your biology changes.

You should not have to wonder whether your peptide protocol is working.
You should be able to see it.
Most people do not fail because peptides “do not work.”
They fail because no one built the system around them.

I have been working with Dr Landi for several months now. He is extremely knowledgeable, attentive and responsive. He actually listens which is rare in medicine these days. I’m excited to see what the results are from my protocol in a couple of months. Highly recommend his practice if you’re looking into functional medicine.
Lauren Griffith
Dr. Landi is highly knowledgeable and skilled in the field of functional medicine, but he also possesses a genuine empathy and compassion that is so often lacking in the traditional healthcare system. Dr. Landi connects to each of his patients on a personal level, works with you every step of the way, and makes you feel supported while navigating challenging health obstacles.
Kevin Heckman
I found out about the practice of Functional Dr’e last year and realized this is what I need! Finding Dr Landi so close to home was awesome. We appreciated his candor, knowledge and engaging personality. He exuded caring and interest in me and my situation. I feel he had repeatedly gone the extra mile for me so our collaboration is successful.
Let’s find out whether peptide therapy makes sense for your biology.
Peptides are short chains of amino acids that can act as signaling molecules in the body.
In clinical optimization, peptide pathways may be considered to support repair signaling, metabolic function, mitochondrial health, recovery, gut integrity, immune regulation, or longevity-related goals.
They are not magic. They are not first-line for everyone. They should be used in context.
Buying peptides online often means no medical intake, no labs, no contraindication screening, no dosing strategy, no safety monitoring, and no quality verification.
HFW uses peptide therapy within a physician-supervised model. We review your history, labs, symptoms, medications, risk factors, goals, and response over time.
We do not build protocols around research-only or gray-market products.
No.
Peptides are tools, not default treatments. Some patients need gut restoration, hormone optimization, nutrient repair, mitochondrial support, inflammation reduction, metabolic correction, or better sleep and stress regulation first.
We start with the reason your body is struggling — not the peptide.
Peptides can carry risks, especially when used without proper screening, dosing, sourcing, and monitoring.
That is why HFW reviews safety labs, medical history, medications, contraindications, goals, and follow-up markers before and during therapy.
No peptide is appropriate for every patient.
Some peptide-related therapies may involve compounded medications when clinically and legally appropriate.
Compounded drugs are not FDA-approved in the same way commercially approved medications are, and availability depends on federal law, state rules, pharmacy standards, clinical indication, and provider judgment. FDA materials emphasize that compounding from bulk drug substances carries patient-safety considerations and is subject to 503A and 503B limits. (U.S. Food and Drug Administration)
HFW may consider peptide pathways for metabolic health, body composition, recovery, tissue support, gut repair, mitochondrial optimization, cognitive clarity, immune regulation, inflammation support, hormone-supportive care, and longevity.
The exact protocol depends on your testing, symptoms, safety markers, goals, and clinical fit.
When clinically and legally appropriate, your provider may discuss specific peptide or peptide-adjacent pathways such as NAD+ support, mitochondrial support, metabolic signaling, recovery support, gut repair support, or bioregulator therapy.
Specific compounds are not automatic and are not selected from a menu. They are considered only after your provider reviews your labs, history, risks, goals, and availability.
Bioregulators are peptide-based compounds used in longevity-focused protocols to support organ-specific resilience and cellular repair pathways.
At HFW, bioregulators may be considered alongside peptide therapy when biological age, organ-system health, immune resilience, circadian rhythm, vascular health, or cellular recovery are part of the care plan.
Many protocols are structured over 3–6 months, depending on your goals, testing, response, safety markers, and clinical fit.
Some therapies may be cycled, pulsed, adjusted, paused, or discontinued based on how your body responds.
The goal is not endless treatment. The goal is measurable, strategic progress.
Yes.
Peptide therapy should not start blindly. Testing may include bloodwork, safety markers, hormones, thyroid, metabolic markers, gut testing, mitochondrial markers, biological age testing, nutrient testing, or body composition assessment.
Better data allows for safer, more precise protocols.
Peptide pathways may be considered for metabolic function, insulin response, cravings, body composition, or lean mass preservation when clinically appropriate.
But HFW does not treat peptides as a weight-loss shortcut. We evaluate hormones, insulin, thyroid, gut health, inflammation, mitochondrial function, body composition, nutrition, and lifestyle first.
Peptide therapy may be considered as part of a broader plan to support tissue repair pathways, recovery capacity, and inflammation regulation.
We also evaluate why recovery is poor in the first place — sleep, hormones, mitochondrial function, nutrient status, gut health, stress physiology, and inflammatory load.
In some cases, peptide pathways may be considered to support gut lining integrity, inflammation regulation, repair signaling, and digestive resilience.
But gut symptoms still need root-cause testing. HFW may use GI-MAP, bloodwork, food sensitivity testing, nutrient testing, and stress or hormone evaluation before building a gut-focused protocol.
Peptide and bioregulator therapy are typically considered as member add-ons when clinically appropriate.
Members receive ongoing oversight, quarterly consults, quarterly bloodwork review, protocol adjustments, and discounts on peptides, bioregulators, compounds, supplements, and additional testing.
No. HFW is 100% telehealth.
Consultations happen virtually. Lab kits can be shipped to your home, bloodwork can be coordinated locally when needed, and eligible prescriptions may be managed through appropriate pharmacy partners.
HFW operates on a cash-pay model. HSA and FSA cards are accepted where applicable, and all major credit and debit cards are accepted.
This model allows more time, deeper testing, ongoing monitoring, and proactive care that is not limited by insurance-based sick-care rules.
