What Are Peptides, and How Do They Work?
Peptide Therapy has emerged as a powerful tool in personalized medicine.
Peptides show promise in improving tissue repair, metabolic health, cellular aging, body composition, and more.
At Defy Medical, we offer a comprehensive range of peptide therapies designed to help patients meet their wellness goals.
But what exactly are peptides, and how can they support your health journey? Let’s explore the science behind these compounds.


Understanding Peptide Therapy
Peptides are short chains of amino acids that act as signaling molecules in the body. They direct specific biological processes.
Unlike hormones that can have widespread effects throughout multiple systems, peptides work more precisely. These amino acid chains target specific pathways to support healing, recovery, metabolism, cellular health, or other benefits depending on the peptide.
Each peptide serves a unique purpose, and many patients work with their Defy Medical provider to combine peptides and other therapies for best results. Read on to learn about the types of peptides Defy Medical offers.
BPC-157 for Wound Healing and Repair
If you’re dealing with an injury, chronic pain, or digestive issues, BPC-157 may be a useful starting point.
This synthetic peptide is derived from a naturally occurring compound found in gastric fluid.
In research, BPC-157 has displayed an ability to repair tendons, ligaments, and muscle tissue while promoting healthy blood flow to damaged areas.
Originally studied for its protective effects on the digestive system, BPC-157 is now commonly prescribed for musculoskeletal injuries and gastrointestinal irritation. Many patients report noticeable improvements in mobility and comfort within their first treatment cycle.
TB-500 To Treat Injuries
TB-500 has shown promise in supporting tissue regeneration and cell migration (important for tissue repair).
These effects may make TB-500 particularly valuable for complex injuries or injuries that have taken a long time to heal.
Many patients utilize TB-500 in combination with BPC-157 for enhanced benefits, especially when dealing with long-term injuries or inflammation.
TB-500 may also help improve flexibility and mobility during the healing process.
GHK-Cu for Anti-Aging
GHK-Cu is a naturally occurring copper-binding peptide that contributes to skin regeneration, tissue repair, and more.
By delivering bioavailable copper to tissues, it supports multiple biological processes involved in healing and maintenance. GHK-Cu levels decline naturally as we age, leading to many signs of aging.
GHK-Cu peptide Therapy is particularly popular for skin rejuvenation, wound healing, and anti-aging effects. GHK-Cu may also support healthy connective tissue, hair health, and antioxidant activity throughout the body.
Defy Medical offers access to injectable GHK-Cu for peptide therapy. We also offer GHK-Cu skin cream for a targeted approach that aims to improve skin texture and appearance.


AOD-9604 for Fat Metabolism Support
AOD-9604 is a modified fragment of human growth hormone.
It’s able to improve fat metabolism while avoiding effects on growth and blood sugar regulation.
By supporting the breakdown of stored fat and limiting the formation of new fat, AOD-9604 may support a comprehensive body composition plan that includes proper nutrition and physical activity.
MOTS-C for Metabolic Health
MOTS-C is at the core of cellular energy production and the metabolism.
It has shown benefit in supporting healthy metabolic function by promoting insulin sensitivity, glucose regulation, and cellular energy utilization.
This peptide may be particularly valuable for patients who are focused on metabolic health, body composition improvement, and overall energy efficiency. It’s often incorporated into protocols that include intermittent fasting or structured diets.
Sermorelin for Growth Hormone Restoration
Sermorelin is a Growth Hormone-Releasing Hormone (GHRH) analogue, meaning it stimulates the pituitary gland to release human growth hormone (hGH).
By encouraging the body’s own hGH release, Sermorelin can help maintain natural hormone balance while significantly improving hGH and insulin-like growth factor 1 (IGF-1) levels in the blood.
Sermorelin is commonly prescribed for Adult Growth Hormone Deficiency (AGHD) and low natural GH production. It may also be prescribed to offset natural hGH decreases as patients age.
Many patients report feeling more energetic, recovering better from exercise, and experiencing improved body composition within their first 12-week treatment cycle.
Tesamorelin for Growth Hormone Production
Tesamorelin stimulates the body’s natural production of human growth hormone (hGH).
Similar to Sermorelin, Tesamorelin is a secretagogue that triggers the release of hGH. But while Sermorelin has a general effect on hGH production, Tesamorelin acts more quickly and directly on fat burning. It has demonstrated ability in reducing visceral fat (fat stored around internal organs) while preserving lean muscle mass.
Tesamorelin may also support metabolic and lipid health. This makes it a useful potential tool for patients struggling with stubborn abdominal fat despite proper diet and exercise.
Ipamorelin for Selective Growth Hormone Release
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist.
Its selectivity differentiates it from other growth hormone releasing peptides. It’s been shown to stimulate growth hormone release without significantly affecting cortisol, acetylcholine, prolactin, or aldosterone levels.
This selective action makes Ipamorelin a commonly prescribed option for body composition and weight loss goals. Ipamorelin is also popular for weight loss because it shows minimal effects on hunger signaling, unlike other growth hormone releasing peptides.
CJC-1295 to Boost hGH
CJC-1295 is a growth hormone-releasing hormone (GHRH) analogue that binds to receptors in the pituitary gland to stimulate growth hormone secretion.
CJC-1295 has a longer half-life than similar peptides, approximately 30 minutes compared to Sermorelin’s 8-12 minutes. Because of this, CJC-1295 is often combined with other peptides for a synergistic effect.
CJC-1295 is frequently used to encourage fat burning and healthy body composition. It may also be prescribed to support lean muscle, improve lipid profiles, trigger deep wave sleep patterns, and help with tissue repair and injury recovery.
CJC-1295 is often used in combination with Ipamorelin because the two peptides perform slightly different functions.
CJC-1295 acts as a GHRH analogue binding to pituitary receptors, while Ipamorelin functions as a ghrelin receptor agonist. This complementary mechanism of action can make Peptide Therapy more effective.
IGF-LR3 for Muscle Recovery and Tissue Repair
IGF-1 LR3 is a modified form of insulin-like growth factor-1. It’s designed to remain active longer than naturally occurring IGF-1.
In studies, IGF-1 LR3 has demonstrated success in supporting muscle recovery by promoting protein synthesis and tissue regeneration.
This peptide requires careful medical supervision and is typically used in short-term protocols. Because IGF-1 plays a role in glucose regulation, patients should monitor for symptoms of low blood sugar like lightheadedness or shakiness.
This therapy may not be appropriate for individuals with a personal history of cancer.


Epithalon for Healthy Aging
Epithalon supports cellular health and may help combat cellular aging.
It’s derived from epithalamin, a peptide associated with the pineal gland. Epithalon is notable for its effects on sleep quality and circadian rhythm. It also shows promise in supporting immune function and protecting cells from oxidative stress.
Epithalon may accomplish this by increasing the body’s production of an enzyme called telomerase. This enzyme helps to repair and expand telomeres, the protective covers at the ends of chromosomes. It may also act on the hypothalamic-pituitary axis (HPTA) to increase melatonin production, which is crucial for falling asleep.
Rather than continuous daily use, Epithalon is usually administered in strategic short cycles throughout the year to support long-term health.
Kisspeptin: Reproductive Hormone Regulation
Kisspeptin plays a central role in regulating the body’s reproductive hormone system through the hypothalamic-pituitary-gonadal axis.
It can support the healthy release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for fertility and reproductive function in men and women.
This peptide is particularly promising for patients who are working to optimize hormonal balance and reproductive health under medical supervision. Regular follow-up with your provider ensures appropriate hormone response throughout treatment.
Peptide Dosage Forms
Defy Medical offers peptides in multiple forms to accommodate patient preferences and treatment goals.
Injections are the most common and preferred type of peptide delivery. They offer reliable absorption and consistent blood levels, plus they allow for quick dosage adjustment based on how the body responds.
Certain peptides are available as oral capsules. This delivery system may be preferable for patients who want to avoid injections. While convenient, the capsules must be absorbed through the digestive tract, which is not as effective as injecting into the bloodstream.
GHK-Cu is available as a scalp cream and face cream. When applied topically, this peptide can improve skin and hair texture and appearance.
Combination Therapies
Some peptides offer greater effects when combined. For example, BPC-157 and TB-500 are often prescribed as a combination therapy to help repair muscles and joints after injury.
Another effective combination is AOD-9604 and MOTS-C to improve metabolic health and encourage weight loss. Tesamorelin is also sometimes added to this protocol for even more optimized fat-burning.
Ipamorelin is frequently combined with CJC-1295 to further improve growth hormone production. These peptides stimulate the secretion of hGH in different ways, which can boost hGH production in short bursts and longer controlled releases.
Combine other Defy Medical Therapies
Patients can also combine peptides with other therapies offered by Defy Medical. For example, many men begin Testosterone Replacement Therapy (TRT) alongside Peptide Therapy for enhanced effects.
Similarly, weight loss patients may choose to begin Peptide Therapy alongside GLP-1s like Semaglutide and Tirzepatide for greater fat burning and body composition improvement.
