Peptide therapy represents one of the most promising frontiers in functional medicine, offering targeted solutions for everything from hormone optimization to immune system support. These short chains of amino acids act as biological messengers, directing specific cellular functions throughout the body with remarkable precision.
Unlike traditional medications that often create broad systemic effects, peptides work by mimicking or enhancing the body’s natural biological processes. This approach aligns perfectly with functional medicine’s core principle of addressing root causes rather than merely managing symptoms.
There are many different kinds of peptides that can help with a myriad of health conditions—but how will you know which are right for you? Let’s dive into how to incorporate this therapy into your routine, and how our integrative team at hol+ can help.
This comprehensive guide explores the most effective peptides for various health concerns and their proven benefits.
Understanding Peptide Therapy—The Basics
Peptides are naturally occurring compounds made up of short chains of amino acids. Your body produces thousands of different peptides, each serving specific functions like hormone regulation, tissue repair, and immune system modulation.
Therapeutic peptides used in functional medicine are either identical to those your body produces naturally or carefully designed to enhance specific biological processes. This biocompatibility makes them generally well-tolerated with minimal side effects compared to synthetic pharmaceuticals.
The therapeutic potential of peptides lies in their specificity. Each peptide targets particular receptors or pathways, allowing practitioners to address specific health concerns with precision. This targeted approach reduces the risk of unwanted side effects while maximizing therapeutic benefits (1).
Modern peptide therapy has evolved significantly, with improved synthesis methods and delivery systems enhancing their stability and effectiveness. Today’s peptides undergo rigorous testing to ensure purity and potency.

Top Peptides for Hormonal Balance and Anti-Aging
Growth Hormone Releasing Peptides (GHRPs)
Ipamorelin stands out as one of the most popular peptides for hormone optimization. This growth hormone releasing peptide stimulates natural growth hormone production without significantly affecting cortisol or prolactin levels (2). Users often report improved sleep quality, increased lean muscle mass, and enhanced recovery from exercise.
Sermorelin works similarly by stimulating the pituitary gland to release growth hormone naturally (3). Unlike synthetic growth hormone injections, sermorelin maintains the body’s natural pulsatile release pattern, reducing the risk of side effects while supporting healthy aging processes (4).
CJC-1295 DAC provides longer-lasting growth hormone stimulation due to its extended half-life. This peptide requires less frequent dosing while maintaining steady growth hormone elevation, making it convenient for long-term therapy protocols (5).
Reproductive Health Peptides
Kisspeptin-10 shows remarkable promise for reproductive health in both men and women. This peptide regulates the hypothalamic-pituitary-gonadal axis, supporting healthy testosterone and estrogen production. Research indicates significant benefits for libido, fertility, and overall reproductive function (6).
PT-141 (Bremelanotide) addresses sexual dysfunction through central nervous system pathways rather than vascular mechanisms (7). This approach makes it effective for both psychological and physiological causes of decreased libido, offering hope for individuals who haven’t responded to traditional treatments.

Cognitive Enhancement and Neuroprotective Peptides
Nootropic Peptides
Noopept demonstrates powerful cognitive enhancement properties, improving memory formation, focus, and mental clarity (8). This peptide crosses the blood-brain barrier effectively, providing neuroprotective benefits while enhancing cognitive performance (9).
Selank offers anxiolytic (anti-anxiety) effects alongside cognitive enhancement, making it particularly valuable for individuals dealing with stress-related cognitive decline (10). This peptide modulates GABA receptors while supporting neuroplasticity and memory consolidation.

Neuroregeneration Support
Cerebrolysin contains naturally occurring neurotrophic factors that support brain health and recovery from neurological damage (11). While technically a peptide mixture rather than a single compound, it shows remarkable benefits for cognitive function and neuroprotection.
BPC-157 extends beyond gut healing to support neurological function. Research suggests this peptide may help protect against neurotoxicity while promoting neural tissue repair and regeneration (12).
Metabolic Health and Weight Management
Fat Loss Peptides
AOD-9604 specifically targets fat metabolism without affecting blood sugar levels or muscle tissue (13). This peptide fragment of growth hormone focuses exclusively on lipolysis, making it an excellent choice for body composition improvement.
Tesamorelin effectively reduces visceral adipose tissue, particularly beneficial for individuals with metabolic syndrome or stubborn abdominal fat. Clinical studies show significant reductions in visceral fat mass with consistent use (14).
Metabolic Regulation
Semaglutide and other GLP-1 receptor agonists revolutionize weight management by regulating appetite, slowing gastric emptying, and improving insulin sensitivity. These peptides address multiple aspects of metabolic dysfunction simultaneously.
Tirzepatide improves glycemic control by increasing insulin sensitivity and lipid metabolism as well as by reducing body weight (15).
Recovery and Performance Enhancement
Tissue Repair Peptides
TB-500 (Thymosin Beta-4) accelerates healing by promoting angiogenesis, reducing inflammation, and supporting tissue regeneration (15). Athletes and active individuals often use this peptide to recover from injuries faster and reduce exercise-induced inflammation.
BPC-157 deserves special mention for its remarkable healing properties. This “body protection compound” supports healing in virtually every tissue type, from tendons and ligaments to the gastrointestinal tract and nervous system (16).
Immune System and Inflammatory Support
Immune Modulation
Thymosin Alpha-1 supports immune system function by enhancing T-cell activity and promoting healthy immune responses (17). This peptide shows particular promise for individuals with compromised immunity or chronic infections.
LL-37 demonstrates antimicrobial properties while supporting immune system balance. Research suggests this peptide may help combat resistant infections while promoting healthy inflammatory responses (18).

Anti-Inflammatory Benefits
Many peptides provide anti-inflammatory benefits as secondary effects. BPC-157, TB-500, and even growth hormone releasing peptides can help reduce chronic inflammation while supporting overall health and recovery.
Safety Considerations and Best Practices
Peptide therapy requires proper medical supervision to ensure safety and effectiveness. Working with a qualified integrative healthcare team familiar with peptide protocols is essential for optimal outcomes.
Quality sourcing remains critical, as peptides can degrade rapidly if not stored and handled properly. Reputable compounding pharmacies and suppliers maintain strict quality control standards to ensure peptide stability and purity.
Individual responses to peptides vary significantly based on factors like age, health status, lifestyle, and genetic factors. Starting with conservative doses and monitoring responses carefully helps optimize protocols while minimizing risks.
Regular monitoring through blood work and clinical assessments helps track progress and adjust protocols as needed. Many peptides require cycling or periodic breaks to maintain effectiveness and prevent desensitization.
Making Peptide Therapy Work for Your Health Goals
Successful peptide therapy begins with clear health goals and comprehensive health assessment. Understanding your specific needs helps determine which peptides might provide the greatest benefits for your situation.
Combining peptides with lifestyle interventions amplifies their effects. Proper nutrition, regular exercise, adequate sleep, and stress management create an optimal environment for peptide therapy success.
