GHK-Cu
GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is a naturally occurring tripeptide first isolated from human plasma in 1973. Studied for over four decades across dermatology and wound-care literature for collagen synthesis, fibroblast activation, and post-procedure skin repair — administered at Luxbae under the medical direction of Dr. Ernst von Schwarz, MD, PhD.

A copper-binding tripeptide with a 40-year research record
GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is a naturally occurring tripeptide first isolated from human plasma in 1973.1 It functions as a copper-binding molecule with documented effects on dermal fibroblast activation, collagen and elastin gene expression, and the cellular signaling involved in wound healing.2 Plasma concentrations of GHK decline measurably with age — from approximately 200 ng/mL at age 20 to roughly 80 ng/mL by age 60 — which has driven interest in its therapeutic application for skin quality and tissue repair.1
At Luxbae, GHK-Cu is one component of the proprietary Glow Fusion protocol, which pairs it with BPC-157 and TB-500 for clients pursuing skin radiance, post-procedure recovery, and inside-out resilience. Every protocol is prescribed and supervised by Dr. Ernst von Schwarz, MD, PhD after a complimentary medical consultation.
GHK binds copper(II) ions with extraordinary affinity, forming the GHK-Cu complex. In preclinical models this complex modulates over 4,000 human genes — many involved in skin remodeling, antioxidant defense, and DNA repair pathways.2
For an aesthetic clientele, GHK-Cu is the most defensible copper peptide in the literature — three decades of peer-reviewed work plus a clean safety profile when prescribed and compounded properly.
What the research actually shows
GHK-Cu has been studied across dermatology, plastic surgery, and wound-care literature for more than four decades. The summaries below cite peer-reviewed sources; individual response varies and is not guaranteed.
Increases expression of collagen, elastin, and proteoglycan synthesis in dermal fibroblasts in controlled studies.3 Relevant to skin firmness, texture, and post-procedure healing.
Cosmetic studies of GHK-Cu formulations reported improvements in fine-line depth, skin density, and photo-aged appearance versus vehicle control.4
Studied for angiogenesis, granulation tissue formation, and accelerated re-epithelialization in chronic wound models.2 Of particular interest after laser resurfacing or microneedling.
Copper peptide formulations have been investigated for follicular function and have been used clinically alongside PRP and minoxidil-based hair-restoration protocols.5
Modulates several oxidative-stress and inflammatory pathways implicated in visible skin aging.2 Often relevant alongside aesthetic procedures that intentionally provoke a controlled inflammatory response.
In Luxbae’s Glow Fusion, GHK-Cu is paired with BPC-157 and TB-500 to layer skin signaling, vascular repair, and systemic tissue-healing pathways in a single program.

How a GHK-Cu protocol typically runs at Luxbae
Dosing, cadence, and delivery method are tailored to you. The outline below describes the most common Glow Fusion variant; your provider will personalize based on labs, current treatments, and goals.
Complimentary medical consultation. We review your goals, current treatments, medical history, and any planned aesthetic procedures.
Your provider determines whether GHK-Cu is best as a standalone or layered with BPC-157, TB-500, or other complementary peptides.
Most clients run 6–12 weeks of Monday-through-Friday morning subcutaneous injections, with weekends off to support recovery.
Your provider sequences peptides around any in-spa treatments and re-evaluates at 6–8 weeks. Dosing adjusts as your response evolves.
Frequently sequenced alongside
- Morpheus8 — pre- and post-treatment to support collagen response and recovery.
- Solaria CO2 Laser — typically introduced post-procedure once the skin barrier has begun to seal.
- Biologique Recherche facials — to reinforce visible texture and tone changes.
- PRP — particularly for hair-restoration combination protocols.
- BPC-157 and TB-500 as part of the full Glow Fusion stack.
Who it’s for — and who should avoid it
GHK-Cu has a long safety record in cosmetic and dermatology literature, but it is not appropriate for everyone. Eligibility is confirmed during your medical consultation, and your full medical history must be disclosed.
- Clients pursuing skin quality, glow, and overall radiance.
- Post-procedure recovery support (microneedling, CO2, Morpheus8, facials).
- Patients seeking aesthetic-leaning longevity protocols.
- Clients pairing with Luxbae’s Glow Fusion or hair-restoration plans.
- Pregnancy or breastfeeding.
- Active cancer or a personal history of cancer.
- Wilson’s disease or known copper-handling disorders.
- Active autoimmune conditions or immunosuppressive therapy.
- Known allergies to peptide compounds.
Possible side effects
Most reported effects are mild and local: redness, swelling, itching, or warmth at the injection site, occasional mild headache or fatigue during the first few days of a protocol. Persistent or unusual symptoms should be reported to your provider promptly.
FDA & regulatory note
GHK-Cu is not FDA-approved as an injectable therapeutic and is currently considered investigational. All Luxbae peptide protocols are administered under direct medical supervision; your provider will review the current regulatory status, mechanism, expected benefits, and risks during your consultation.
