KLOW
Blend GHK-Cu + BPC-157 + TB-500 + KPV
KLOW is the enhanced version of the GLOW stack: on top of the shared core of GHK-Cu + TB-500 + BPC-157, it adds KPV, a tripeptide with powerful anti-inflammatory and immunomodulatory properties. KLOW therefore covers both tissue repair, recovery, and skin radiance AND an anti-inflammatory, digestive comfort, immunomodulation, and overall balance component. It is the most complete stack for those dealing with chronic inflammation, digestive discomfort, or immune imbalances. For research use only.
Potential benefits
Tissue repair
Supports the repair of muscles, tendons, ligaments, and connective tissue.
Digestive comfort
Protects and repairs the intestinal lining, soothing digestive discomfort (KPV).
Anti-inflammatory & balance
Anti-inflammatory and immunomodulatory action (KPV) for overall balance of the body.
Healthy, radiant skin
Stimulates collagen, elastin, and glycosaminoglycans for firmer, more radiant skin.
Recovery & mobility
Faster recovery, improved flexibility, and reduced stiffness.
Mechanism of action
- GHK-Cu (Copper Peptide): stimulates fibroblasts, increases the synthesis of collagen (I, III, IV), elastin, and glycosaminoglycans, is a potent antioxidant, accelerates wound healing, and supports hair health.
- TB-500: promotes cell migration and systemic tissue repair, improves flexibility and mobility, supports recovery, and reduces inflammation and tissue stress.
- BPC-157: localized repair of soft tissue, muscles, tendons, and ligaments, stimulates angiogenesis, protects and repairs the gastric/intestinal lining, anti-inflammatory and healing effect.
- KPV (Lysine–Proline–Valine): inhibits pro-inflammatory cytokines (TNF-α, IL-6, IL-1β), modulates the NF-κB / MAPK pathways and neutrophil migration, soothes the intestinal lining, regulates the immune response, and supports mental clarity.
Evolution over time
Improved sleep, less pain and digestive discomfort, more supple joints.
Faster recovery, reduced inflammation, better mobility, soothed digestion.
Stronger tissue, visible healing, healthier skin, improved overall balance.
Lasting results, ongoing regeneration, better digestive and immune comfort.
Dosages & protocol
Reference dosages
8 wk + 2 off
In the evening or before bedtime (nighttime recovery), after training, or daily for ongoing support. Consistency is key.
Varies by component: GHK-Cu, BPC-157 and KPV have a short plasma half-life (minutes to ~1-2 h); TB-500 has a plasma half-life of a few hours with prolonged tissue retention (several days).
Titration protocol
Stay on one step and let natural accumulation work. Progress slowly.
The complete stack (core + KPV)
KLOW = the shared core of GHK-Cu + TB-500 + BPC-157, enhanced with KPV. Together, they cover repair, recovery, regeneration AND anti-inflammatory/digestive/immune support.
- GHK-Cu — Restructure & regenerate: collagen, elastin, skin radiance, wound healing, hair health.
- TB-500 — Recovery & mobility: muscle and tendon recovery, flexibility, tissue regeneration.
- BPC-157 — Repair & comfort: tissue repair, digestive comfort, reduced inflammation.
- KPV — Anti-inflammatory & immunity: pro-inflammatory cytokines, intestinal lining, immunomodulation.
Who is KLOW for?
KPV provides the missing piece for those whose inflammation or digestion is holding back results.
- Digestive discomfort: bloating, IBS, intestinal permeability.
- Inflammation: joint pain, tendinitis, bursitis.
- Reactive skin: inflammatory acne, eczema, psoriasis, rosacea.
- Immune imbalance and a search for overall well-being.
Administration method
- Subcutaneous (SC) or intramuscular (IM) injection.
- Recommended sites: abdomen, thighs, upper arms (back), hips.
- Needles: 29G – 31G, 4 to 8 mm (SC); 25G – 27G (IM).
- Reconstitute with bacteriostatic water; sterile hygiene, never reuse needles.
No regeneration without a solid foundation
KLOW is described as optimizing the body's natural recovery capacity, with lifestyle habits remaining the foundation of any lasting transformation.
- Sleep: 7 to 9 hours of quality sleep.
- Anti-inflammatory nutrition: protein, antioxidants, omega-3s, zinc, vitamin C, magnesium.
- Hydration: aim for 30 to 40 ml of water per kg of body weight per day.
- Stress management and regular physical activity.
Safety, quality & transparency
- For research use only — not intended for human or animal consumption.
- Highly purified peptides (purity > 98%), batch-by-batch traceability.
- Consult a healthcare professional before any use.
Usage tips
- Start with a low dose and adjust according to individual response.
- Consistency is key: moderate, steady doses give better long-term results.
- Reconstitute with bacteriostatic water; never freeze reconstituted peptides.
- Store refrigerated (2°C – 8°C), away from light; use within ~10 weeks after reconstitution.
- Use a fine needle (29G – 31G, 4 to 8 mm for SC) and sterile equipment; never reuse needles.
- Follow the cycles and allow for appropriate breaks between each cycle.
Good to know / effects to watch
- As a blend (GHK-Cu + BPC-157 + TB-500 + KPV), reported effects combine those of its components.
- Injection-site reactions (redness, discomfort), heightened by the addition of KPV, are frequently described.
- May be observed: transient nausea or dizziness, often attributed to TB-500.
- Metallic taste or local irritation associated with the copper in GHK-Cu; rare hypersensitivity reactions linked to KPV.
- Transient fatigue reported at the start of use.
- Caution with prolonged use: a theoretical copper overload (GHK-Cu) is mentioned. Avoid in cases of active cancer or severe infection.
Storage
- Before reconstitution: lyophilized powder refrigerated (2-8 °C), protected from light.
- After reconstitution (bacteriostatic water): refrigerate (2-8 °C), protect from light; use within the following weeks (up to ~8-10 weeks depending on storage).
- Never freeze the reconstituted solution.
Contraindications
- Pregnancy and breastfeeding.
- Active cancer or history of cancer (proliferation / angiogenesis: GHK-Cu, TB-500, BPC-157).
- Autoimmune disease or immunosuppression: caution (KPV-related immunomodulation).
- Wilson's disease or copper-metabolism disorder (GHK-Cu); severe uncontrolled infection.
- Known hypersensitivity to any of the peptides.
Possible synergistic combinations
The catalog peptides are clickable — to complete or optimize your protocol.
Antioxidants, omega-3s, and polyphenols reinforce the action of KPV.
Cofactor for collagen synthesis.
Support immunity, repair, and recovery.
Deep repair and immune regulation.
Version without KPV, focused on skin/aesthetics/recovery if the anti-inflammatory component is not needed.
