Healing Peptides
16BPC-157 and TB-500 lead this category of peptides researched for tissue repair, tendon healing, gut health, and injury recovery. These compounds are studied for their ability to accelerate the body's natural healing processes across multiple tissue types.
Ara-290
A peptide derived from EPO (the hormone that boosts red blood cells) but engineered to keep only the tissue-protective effects — it doesn't increase red blood cells at all. It activates the body's repair receptors to protect tissues and regenerate nerves. Particularly promising for nerve damage and tissue injury from poor blood flow. People use it for diabetic nerve damage and similar conditions.
BPC-157
A healing compound made from a protein found in stomach fluid. It's the most studied peptide for tissue repair, with research showing it helps heal tendons, ligaments, muscles, the gut, and other organs. It's stable enough to survive stomach acid, so you can take it either by injection under the skin or by mouth.
BPC-157 + TB-500
A two-in-one product that pairs BPC-157 and TB-500 to target different healing pathways. BPC-157 focuses on gut, tendon, and ligament repair by supporting blood vessel growth and nitric oxide signaling, while TB-500 helps cells move to injury sites for body-wide tissue repair. The most popular peptide combination for healing and recovery.
Dermorphin
A powerful opioid peptide first found in the skin of a South American tree frog. It's roughly 30–40 times stronger than morphine at the pain-relief receptor. Highly controversial because it was widely abused in horse racing — given to horses to mask pain and enhance performance — leading to doping scandals and animal welfare concerns.
GHK-Cu
A naturally occurring copper-binding peptide found throughout the body; levels drop after age 20. The most studied cosmetic peptide, with proven effects on collagen production, skin renewal, wound healing, and antioxidant protection. It influences over 4,000 genes, shifting them toward a younger, more regenerative pattern. People use it for skin aging, wound healing, and anti-aging.
Hyaluronic Acid
A naturally occurring substance found in connective tissue, skin, and joint fluid throughout the body. It holds moisture, lubricates joints, and adds volume to skin. Used in many forms: injectable fillers for facial volume, joint injections for arthritis, topical serums for skin hydration, and oral supplements. Different sizes (molecular weights) have different effects. People use it for wrinkles, joint pain, and skin hydration.
IGF-1
Insulin-like Growth Factor 1 — the 70-amino-acid peptide hormone that serves as the primary mediator of growth hormone's anabolic effects throughout the body. Produced mainly by the liver in response to GH signaling, IGF-1 drives protein synthesis, cell proliferation, and tissue growth. FDA-approved as Increlex for primary IGF-1 deficiency, with off-label use in bodybuilding and anti-aging for its potent anabolic and recovery-enhancing properties.
KPV
A small peptide derived from a hormone that regulates skin color. It keeps the strong anti-inflammatory and immune-balancing effects of the full hormone without causing skin tanning or sexual side effects. One of the cleanest anti-inflammatory peptides available, and it works when taken by mouth, injected, or applied to the skin. People use it for gut inflammation, skin conditions, and general inflammation.
LL-37
The body's main antimicrobial peptide — a natural part of the immune system that fights bacteria, viruses, and fungi. Beyond fighting germs, it promotes wound healing, helps regulate inflammation, and stimulates new blood vessel growth at injury sites. The body makes it in response to infection or tissue damage. People use it for wound healing and immune support.
MGF
A natural 'first responder' peptide that your muscles produce when they're damaged by exercise. It activates dormant muscle stem cells and kickstarts the repair process. Think of it as the signal that tells your body to start rebuilding after a workout. The problem is it only lasts 5-7 minutes in the body, making it extremely impractical — which is why the longer-lasting PEG-MGF version exists.
PEG-MGF
The practical, longer-lasting version of MGF. A protective coating (PEG) extends its life from 5 minutes to several hours, making it actually usable. Unlike native MGF which only works where you inject it, PEG-MGF spreads through your body and activates muscle stem cells in multiple muscle groups at once. The most realistic option for anyone interested in MGF's muscle repair benefits.
Pentosan Polysulfate
A compound derived from beechwood. FDA-approved orally (Elmiron) for bladder pain (interstitial cystitis), commonly used as an injection for joint and cartilage repair in osteoarthritis. One of the most popular peptide-adjacent therapies in sports medicine and regenerative clinics. Mimics natural compounds in cartilage to protect joints and reduce inflammation.
TB-500
A naturally occurring peptide found in nearly all human cells that helps cells move and rebuild. It plays a key role in tissue repair, new blood vessel growth, and calming inflammation. One of the most powerful wound-healing peptides identified, with strong results in heart, skin, and eye repair.
TB-500 + BPC-157 + GHK-Cu
A three-in-one healing combo that adds GHK-Cu (copper peptide) to the BPC-157 and TB-500 stack. GHK-Cu helps build collagen, remodel tissue, and fight oxidative damage, complementing the repair and anti-inflammatory effects of the other two. An advanced protocol for comprehensive tissue healing and recovery.
Thymosin Beta-4
The full-length 43-amino-acid peptide naturally produced by the thymus gland — the parent molecule from which TB-500 is derived. Plays a key role in cell movement, tissue repair, wound healing, and reducing inflammation throughout the body. The full-length form may offer broader healing benefits than the TB-500 fragment alone.
VIP
A natural peptide found throughout the body, especially in the nervous system, gut, and lungs. It widens blood vessels, calms inflammation, and helps balance the immune system. Most studied for chronic inflammatory conditions (like mold illness) and high blood pressure in the lungs, where it tones down excessive inflammatory signaling. People use it for CIRS, mold illness, and similar conditions.
