GHK-Cu
Copper Tripeptide (Glycine-Histidine-Lysine)
GHK-Cu is a copper-bound peptide that occurs naturally in the body, with levels that decline as we age. It's studied as a renewal signal for the skin.
How it works
GHK-Cu signals skin cells to produce collagen and elastin, supports antioxidant activity, and is involved in the skin's natural renewal and repair processes.
Improved skin firmness and elasticity
Support for collagen and elastin production
Reduced appearance of fine lines
Wound healing and reduced scarring
Antioxidant support for the skin
Hair follicle and density support
Improved skin hydration and texture
Potential Benefits
Early signs of skin aging — fine lines, dullness, loss of elasticity
Mild collagen decline (roughly 20s–40s)
Uneven skin texture
Recovery after skin or soft-tissue procedures (lasers, microneedling, cosmetic work)
Who it may suit
Common Focus Areas
Skin anti-aging and rejuvenation
Post-procedure healing
Collagen and elastin restoration
Hair health
Tolerability
Generally well tolerated. A brief, harmless color at the injection site can occur due to the copper. Your physician will review specifics.
How it’s used
Used within a physician-guided plan, typically as a small subcutaneous injection on a schedule from a few times weekly up to daily, based on your goals.
KPV
Lysine-Proline-Valine
KPV is a small peptide with anti-inflammatory and potential antimicrobial properties, studied in both skin and gut contexts.
How it works
KPV helps calm inflammatory signaling and supports the intestinal barrier, which is why it's discussed for conditions where inflammation is a central driver.
Reduced inflammatory signaling
Support for the intestinal barrier and gut comfort
Calming of inflammatory skin conditions
Wound-healing support
Immune modulation without suppression
Potential Benefits
Who it may suit
People whose symptoms are driven mainly by inflammation
Inflammatory skin conditions (eczema, dermatitis, rosacea contexts)
Digestive discomfort and inflammatory-bowel contexts
Common Focus Areas
Gut and inflammatory-bowel wellness
Inflammatory and post-procedure skin
Systemic inflammation support
Tolerability
Considered very well tolerated, with mild temporary injection-site reactions most commonly noted.
How it’s used
Given as a small subcutaneous injection or targeted to the area of concern, on a schedule your physician sets — often a few times weekly up to daily.
GLOW
BPC-157 / TB-500 / GHK-Cu Combination
GLOW is a triple-combination formula that pairs the repair peptides BPC-157 and TB-500 with GHK-Cu, the copper peptide central to skin renewal. It's aimed at skin regeneration and recovery together.
How it works
The formula combines three mechanisms — tissue repair, reduced scarring, and collagen/elastin renewal — for a comprehensive approach to skin regeneration.
Skin texture and elasticity support via three mechanisms
Collagen and elastin support
Faster recovery after skin or soft-tissue stress
Reduced appearance of fine lines
Support for even, healthy-looking skin
Potential Benefits
Who it may suit
People focused on overall skin rejuvenation
Recovery after aesthetic procedures
Those wanting repair and anti-aging support together
Common Focus Areas
Skin anti-aging and regeneration
Post-procedure recovery and healing
Comprehensive aesthetic rejuvenation
Tolerability
Generally well tolerated. As with GHK-Cu, a brief harmless color at the injection site can occur.
How it’s used
A single subcutaneous injection combining all three, on a schedule from a few times weekly up to daily, guided by your physician.
KLOW
KPV / BPC-157 / TB-500 / GHK-Cu Combination
KLOW is the most comprehensive combination, adding KPV's anti-inflammatory support to the GLOW formula — four complementary peptides in one.
How it works
KLOW brings together tissue repair, collagen renewal, and anti-inflammatory support, making it a fit when inflammation is a factor alongside regeneration and healing needs.
Comprehensive support across four complementary mechanisms
Anti-inflammatory support (skin and systemic)
Tissue repair and recovery
Collagen, elastin, and antioxidant support
A fit for chronic inflammation alongside healing goals
Potential Benefits
Who it may suit
People with regeneration goals where inflammation is also a factor
Those wanting comprehensive skin and recovery support in one
Common Focus Areas
Inflammatory skin and gut wellness
Comprehensive post-procedure recovery
Systemic inflammation support
Tolerability
All four components are well established and generally well tolerated, with mild injection-site reactions most commonly noted.
How it’s used
A single subcutaneous injection combining all four peptides, on a physician-set schedule.
