Peptides in Integrative Medicine Practice
Integrative medicine lives at the intersection of two ideas: that the body works as a connected system, and that interventions should be supported by evidence. It's not alternative medicine. It's not dismissing conventional treatments.
Integrative medicine lives at the intersection of two ideas: that the body works as a connected system, and that interventions should be supported by evidence. It's not alternative medicine. It's not dismissing conventional treatments. It's the recognition that optimal health requires addressing the whole patient -- physiology, lifestyle, environment, and psychology -- while demanding scientific rigor for every tool in the toolkit.
Peptides fit this framework unusually well. They're endogenous molecules (the body already makes many of them), they work through specific, well-characterized receptor pathways, and they address the systems-level problems that integrative practitioners see daily: chronic inflammation, hormonal decline, immune dysregulation, poor sleep, and impaired tissue repair.
This guide covers how peptides integrate into a holistic practice, which peptides align with integrative medicine principles, and how practitioners and patients can build evidence-based peptide protocols within a whole-person care model.

Why Peptides Belong in Integrative Medicine
Integrative medicine practitioners have historically relied on a combination of conventional pharmaceuticals, nutraceuticals, lifestyle modification, and targeted natural therapies. Peptides add a category that bridges several of these: they're more targeted than most supplements, often safer than synthetic drugs, and work through the body's own signaling systems.
They're endogenous. Many therapeutic peptides are versions of molecules your body already produces. BPC-157 is derived from human gastric juice. GHK-Cu circulates naturally in human plasma. DSIP is a naturally occurring brain peptide. This aligns with integrative medicine's preference for working with the body's existing biology rather than overriding it.
They're multi-system. Single peptides often affect multiple organ systems through a common mechanism. BPC-157 heals gut, tendon, ligament, muscle, and nerve tissue. GHK-Cu activates 4,000+ genes across tissue types. This systems-level activity matches integrative medicine's whole-person orientation.
They're specific. Unlike broad-spectrum anti-inflammatories or immunosuppressants, peptides tend to modulate rather than suppress. Selank reduces anxiety without sedation. Thymosin alpha-1 supports immune function without triggering autoimmunity. This precision fits the integrative principle of minimum effective intervention.
They complement lifestyle medicine. Peptides don't replace diet, exercise, sleep, and stress management -- they amplify their effects. Growth hormone peptides work better with regular exercise. Sleep peptides work better with good sleep hygiene. This complementary relationship is central to integrative practice.
The Integrative Medicine Framework for Peptide Therapy
Integrative medicine evaluates patients through multiple lenses simultaneously. Here's how peptides map to that framework:
The Functional Medicine Matrix Applied to Peptides
| Functional System | Common Dysfunction | Relevant Peptides |
|---|---|---|
| Assimilation (gut) | Increased permeability, dysbiosis, IBS | BPC-157, KPV, VIP |
| Defense & Repair | Chronic inflammation, poor healing | BPC-157, TB-500, GHK-Cu, KPV |
| Energy | Mitochondrial dysfunction, fatigue | MOTS-c, SS-31 |
| Biotransformation | Toxic burden, oxidative stress | GHK-Cu (antioxidant genes), glutathione peptides |
| Communication | Hormonal imbalance, neurotransmitter issues | CJC-1295/ipamorelin, semax, selank |
| Transport | Cardiovascular dysfunction | VIP, natriuretic peptides |
| Structural | Joint degeneration, sarcopenia, bone loss | BPC-157, TB-500, GH peptides |
Root Cause vs. Symptom Management
Integrative medicine's core principle is addressing root causes. Peptides can serve both roles:
Root cause examples:
- BPC-157 for intestinal permeability (addressing a cause of systemic inflammation, not just treating the inflammation)
- MOTS-c for mitochondrial dysfunction (addressing the energy deficit, not just the fatigue)
- Epitalon for melatonin restoration (addressing pineal decline, not just providing exogenous melatonin)
Symptom management examples:
- Selank for acute anxiety (providing relief while the root cause is addressed through other means)
- DSIP for acute insomnia (improving sleep while underlying causes are investigated)
- GH peptides for fatigue (supporting energy while metabolic workup proceeds)
The best integrative peptide protocols use symptom-level peptides for immediate relief while root-cause peptides work on deeper resolution.
Core Peptides for Integrative Practice
BPC-157: The Integrative Foundation
BPC-157 is arguably the most aligned peptide with integrative medicine principles because it:
- Is derived from the body's own gastric protective system
- Addresses gut health (a cornerstone of functional medicine)
- Has systemic effects beyond the gut (joints, muscles, brain)
- Promotes healing rather than suppressing symptoms
- Has shown protective effects against medication side effects (NSAIDs, alcohol)
Integrative practitioners use BPC-157 for:
- Leaky gut / increased intestinal permeability
- IBS and functional GI disorders
- Tendinopathy and chronic musculoskeletal pain
- Post-surgical healing
- Gut recovery after antibiotic use
For a complete profile, see our BPC-157 guide.
Thymosin Alpha-1: Immune Modulation
Immune dysregulation is a central theme in integrative medicine -- from chronic infections to autoimmunity to cancer risk. Thymosin alpha-1 is the most well-evidenced immune-modulating peptide:
- FDA-approved (as Zadaxin) in multiple countries
- Modulates rather than stimulates or suppresses immunity
- Supports both innate and adaptive immune function
- Decades of clinical safety data
- Used in conventional oncology as an adjunct
Integrative applications:
- Chronic viral infections (EBV reactivation, chronic hepatitis)
- Recurrent infections suggesting immune suppression
- Adjunctive cancer care (with oncologist coordination)
- Post-COVID immune recovery
- Vaccine response optimization in older adults
VIP: The Multi-System Regulator
VIP is a 28-amino acid neuropeptide that integrative practitioners have used for complex, multi-system patients:
- Modulates the HPA axis (cortisol regulation)
- Anti-inflammatory throughout the GI tract
- Neuroprotective
- Regulates circadian rhythm at the SCN level
- Addresses biotoxin illness (CIRS/mold illness)
VIP is particularly relevant in the integrative context because it addresses the interconnected gut-brain-immune axis that functional medicine emphasizes. For patients with chronic inflammatory response syndrome (CIRS), VIP is one of the final steps in Dr. Ritchie Shoemaker's treatment protocol.
Growth Hormone Peptides: Hormonal Optimization
CJC-1295 and ipamorelin restore physiological GH secretion in the context of age-related decline. In integrative practice, this is framed as hormonal optimization rather than hormone replacement:
- The body's own feedback loops remain intact
- GH release follows a natural pulsatile pattern
- The intervention supports the system rather than overriding it
- Dosing is guided by IGF-1 levels and clinical response
This approach aligns with integrative medicine's preference for supporting endogenous physiology rather than replacing it.
Peptides and the Gut-Brain-Immune Axis
The gut-brain-immune axis is the central organizing principle of much integrative medicine. These three systems communicate bidirectionally through peptide signaling, cytokines, the vagus nerve, and the microbiome. Dysfunction in one affects the others.
How Peptides Address Each Node
Gut node:
- BPC-157: Heals intestinal mucosa, restores gut barrier function
- KPV: Reduces gut inflammation through NF-kB inhibition
- VIP: Protects enteric neurons, modulates gut immunity
Brain node:
- Semax: Increases BDNF, supports neuroplasticity
- Selank: Modulates GABA and serotonin, reduces neuroinflammation
- DSIP: Normalizes cortisol, promotes restorative sleep
Immune node:
- Thymosin alpha-1: Restores T-cell function, modulates immune response
- LL-37: Antimicrobial defense
- VIP: Anti-inflammatory, regulatory T-cell support
The Integrative Advantage
Conventional medicine treats gut, brain, and immune issues in separate specialties. Integrative medicine recognizes their interconnection. Peptide therapy allows practitioners to address all three nodes simultaneously:
Example: A patient presenting with IBS, anxiety, and recurrent infections.
| Target | Peptide | Mechanism |
|---|---|---|
| Gut barrier repair | BPC-157 | Mucosal healing, angiogenesis |
| Anxiety reduction | Selank | GABA modulation |
| Immune support | Thymosin alpha-1 | T-cell restoration |
| Cortisol normalization | DSIP (evening) | HPA axis regulation via sleep |
This multi-peptide approach treats the interconnected system, not isolated symptoms.
Combining Peptides with Functional Medicine Testing
Integrative practitioners use advanced testing to identify specific dysfunctions. Peptide selection becomes more precise with objective data.
| Test | What It Reveals | Peptide Implication |
|---|---|---|
| IGF-1, GH stimulation | Growth hormone status | CJC-1295/Ipamorelin if deficient |
| Intestinal permeability (zonulin) | Leaky gut severity | BPC-157 for gut healing |
| Comprehensive stool analysis | Gut inflammation, dysbiosis | BPC-157, KPV for inflammation |
| Cortisol (4-point salivary) | HPA axis pattern | DSIP for cortisol normalization |
| BDNF (serum) | Neurotrophic factor levels | Semax if low |
| NK cell function | Immune surveillance capacity | Thymosin alpha-1 if low |
| Telomere length | Cellular aging marker | Epitalon if shortened |
| Organic acids (mitochondrial markers) | Mitochondrial function | MOTS-c, SS-31 if impaired |
| Inflammatory markers (CRP, IL-6) | Systemic inflammation | KPV, BPC-157 |
This test-then-treat approach replaces generic protocols with personalized interventions -- a hallmark of integrative medicine.
Peptides Alongside Conventional Treatments
Integrative medicine doesn't reject conventional care. It adds to it. Peptides can complement standard medical treatments.
Surgical Recovery
Conventional: standard post-operative care Integrative addition: BPC-157 + TB-500 for accelerated tissue repair, CJC-1295/ipamorelin for GH-supported recovery, thymosin alpha-1 for immune support during hospitalization.
Autoimmune Disease
Conventional: immunosuppressive medications Integrative addition: Thymosin alpha-1 for immune modulation (separate from immunosuppressants -- discuss with rheumatologist), BPC-157 for gut barrier support (since intestinal permeability is implicated in many autoimmune conditions), selank for stress-related immune exacerbation.
Depression and Anxiety
Conventional: SSRIs, psychotherapy Integrative addition: Selank for GABA-mediated anxiolysis (complementary to SSRIs), semax for BDNF support (the same mechanism targeted by antidepressants but through a different pathway), DSIP for sleep optimization (poor sleep worsens depression).
Cancer Care
Conventional: surgery, chemotherapy, radiation, immunotherapy Integrative addition: Thymosin alpha-1 as immune adjunct (used in conventional oncology in some countries), GHK-Cu for wound healing post-surgery, BPC-157 for chemotherapy-related GI damage. Always coordinate with the oncology team.
Metabolic Syndrome
Conventional: metformin, statins, antihypertensives Integrative addition: MOTS-c for insulin sensitivity (targets the same AMPK pathway as metformin), CJC-1295/ipamorelin for body composition improvement, BPC-157 for gut health (microbiome plays a role in metabolic function).
Peptides and Lifestyle Medicine
The foundation of integrative medicine is lifestyle. Peptides amplify lifestyle interventions rather than replacing them.
Exercise + GH peptides. Exercise is the most potent natural stimulator of GH release. CJC-1295/ipamorelin amplifies this signal. A patient doing regular resistance training with evening GH peptides gets more from both the training and the peptide than either alone.
Meditation + selank/semax. Our meditation and stress management guide covers this in detail. The short version: selank reduces the neurochemical noise that makes meditation difficult, and semax amplifies the BDNF that meditation produces.
Nutrition + BPC-157. An anti-inflammatory diet supports gut health. BPC-157 accelerates gut barrier repair. Together, the dietary intervention removes the ongoing insult while the peptide heals the existing damage.
Sleep hygiene + DSIP. Sleep hygiene creates the behavioral conditions for good sleep. DSIP promotes the delta-wave activity that constitutes deep sleep. Our sleep optimization guide covers the combination approach.
Cold/heat exposure + peptides. These synergistic therapies pair naturally with peptide protocols. See our cold/heat guide and red light therapy guide.
Clinical Decision Framework
For practitioners incorporating peptides into integrative practice, this decision framework ensures systematic, evidence-based prescribing.
Step 1: Comprehensive Assessment
- Complete medical history and medication review
- Functional medicine-style intake (timeline, triggers, mediators)
- Advanced lab panel (hormonal, inflammatory, immune, metabolic, nutrient)
- Lifestyle assessment (sleep, exercise, diet, stress, environment)
Step 2: Root Cause Identification
- Map symptoms to functional medicine matrix categories
- Identify upstream drivers vs. downstream symptoms
- Prioritize: which system dysfunction, if corrected, would produce the largest cascade of improvement?
Step 3: Foundational Interventions First
- Diet modification
- Sleep optimization
- Exercise prescription
- Stress management
- Nutrient repletion (vitamin D, magnesium, B vitamins, omega-3s)
- These are non-negotiable precursors to peptide therapy
Step 4: Targeted Peptide Selection
- Match peptides to identified dysfunctions
- Start with 1-2 peptides targeting the primary dysfunction
- Use the lowest effective dose
- Set measurable outcomes (lab targets, symptom scores)
Step 5: Monitor and Adjust
- Re-test labs at 8-12 weeks
- Track symptom scores monthly
- Adjust doses based on response
- Add or remove peptides as the clinical picture evolves
- Regular check-ins on lifestyle compliance (peptides without lifestyle = limited benefit)

Patient Education and Informed Consent
Integrative medicine values informed consent and shared decision-making. When introducing peptides, patients should understand:
What peptides are. Short chains of amino acids that signal specific biological processes. Many are natural molecules that the body already produces in declining quantities.
What they can and can't do. Peptides are not magic. They modulate specific biological pathways. They work best alongside lifestyle optimization. They don't cure diseases.
The evidence landscape. Some peptides (thymosin alpha-1, semaglutide, PT-141) have FDA approval and extensive clinical data. Others (BPC-157, TB-500) have strong preclinical evidence but limited human clinical trials. Patients deserve transparency about where each peptide falls on the evidence spectrum.
Regulatory considerations. The regulatory environment for peptides is evolving. The FDA's position on peptide compounding has changed recently, affecting availability of some compounds. Patients should understand the legal and regulatory context.
Monitoring requirements. Lab work before, during, and after peptide therapy is essential, not optional. Patients who aren't willing to do regular blood work aren't good candidates for peptide therapy.
The Regulatory Landscape
Integrative practitioners must navigate a complex regulatory environment.
FDA-approved peptides (semaglutide, liraglutide, PT-141/Vyleesi, thymosin alpha-1/Zadaxin in some countries) can be prescribed conventionally.
Compounded peptides have faced increasing FDA scrutiny. The 503A vs. 503B compounding framework determines which peptides can be compounded and by whom.
Research peptides exist in a legal gray area. While legal to sell for research purposes, prescribing them for human use requires clinical judgment and appropriate informed consent.
Practitioners should:
- Stay current on FDA rulings (the landscape changes frequently)
- Work with reputable compounding pharmacies that follow USP standards
- Document clinical rationale for off-label or compounded peptide use
- Maintain thorough informed consent documentation
- Support patients' access to third-party testing when using compounded products
Frequently Asked Questions
How do integrative medicine peptide protocols differ from anti-aging clinic protocols? Integrative medicine places peptides within a comprehensive treatment plan that includes root cause analysis, lifestyle modification, and conventional care coordination. Anti-aging clinics sometimes prescribe peptides in isolation without the broader systems assessment. The peptides may be the same; the clinical framework around them differs.
Can patients request peptide therapy, or should it only come from the practitioner? Both. Patient-initiated requests are common and legitimate. The practitioner's role is to evaluate whether the requested peptide is appropriate given the patient's full clinical picture, recommend alternatives if better options exist, and ensure proper monitoring.
How does insurance handle peptide therapy? FDA-approved peptides (GLP-1 agonists, PT-141) may be covered by insurance. Compounded peptides are typically not covered. Most integrative medicine peptide protocols are out-of-pocket expenses. Our peptide therapy insurance guide covers the details.
What's the minimum lab panel for initiating peptide therapy? At minimum: CBC, comprehensive metabolic panel, lipid panel, HbA1c, IGF-1 (if using GH peptides), thyroid panel, vitamin D, inflammatory markers (CRP, homocysteine), and age-appropriate cancer screening. Functional medicine practitioners often add gut health panels, adrenal testing, and neurotransmitter metabolites.
Are peptides safe to combine with herbal supplements and nutraceuticals? Most peptides are compatible with common supplements. Potential areas of caution:
- GABAergic herbs (kava, valerian) with selank: potential additive sedation
- Blood-sugar-lowering herbs (berberine, gymnema) with GH peptides: opposing effects on glucose
- Anti-inflammatory herbs (curcumin, boswellia) with BPC-157: potentially complementary, not contraindicated Always review the full supplement list alongside peptide protocols.
The Bottom Line
Peptides are a natural fit for integrative medicine because they work through the body's own signaling systems, address the multi-system dysfunctions that integrative practitioners treat daily, and complement lifestyle interventions rather than replacing them.
The integrative approach to peptide therapy is distinct: root cause analysis before prescription, comprehensive testing to guide selection, lifestyle optimization as the foundation, conventional care coordination, transparent patient education, and ongoing monitoring.
For practitioners, peptides add a precise, biologically aligned tool to the integrative toolkit. For patients, they offer targeted support for the specific biological systems that chronic illness, aging, and modern life compromise.
The key is integration itself -- not peptides alone, not lifestyle alone, not conventional medicine alone, but all of them working together within a coherent framework that treats the whole person.
