GHK-Cu

Q: What is GHK-Cu?

Copper tripeptide. Glycyl-histidyl-lysine bound to copper, found naturally in blood. Supports collagen production and wound healing; widely used in skin and hair cosmetics, injected forms are experimental.

Q: How much does GHK-Cu cost?

Q: Where can I buy GHK-Cu?

Q: How much bacteriostatic water for 50 mg of GHK-Cu?

Adding 2 mL of bacteriostatic water to a 50 mg vial of GHK-Cu gives 25 mg/mL: each 10 units on a U-100 insulin syringe holds 2,500 mcg. With 1 mL it's 50 mg/mL (5,000 mcg per 10 units); with 3 mL, 16.667 mg/mL (1,666.7 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 40 mg, 50 mg, 80 mg, 100 mg, 200 mg, 1,000 mg.

Q: Does GHK-Cu work? What does the research say?

Evidence grade B (some human evidence), from 14 papers: Only one small RCT (13 patients, topical after laser resurfacing), which found no objective benefit; everything else is cell and animal work. Most evidence for GHK-Cu comes from cell-culture and animal studies (wound healing, lung and muscle injury, inflammation models). Controlled human data are very sparse: the only randomized trial among the candidates (13 patients after CO2 laser resurfacing) found no objective benefit, and recent systematic reviews describe GHK-Cu as promising but clinically unproven. Added studies are further cell, animal and review work, plus one uncontrolled human hair study of a multi-ingredient product that cannot be attributed to GHK-Cu. See the papers.

Q: Are there clinical trials of GHK-Cu?

ClinicalTrials.gov lists 1 registered trials of GHK-Cu: 1 active, 0 completed. Examples: Topical GHK-Cu Gel for Acute Skin Wound Healing (Recruiting, Phase 2, 60 people).

Q: What dose of GHK-Cu was used in studies?

GHK-Cu is studied in people. adults after CO2 laser resurfacing around the mouth (randomized, skin-care regimen with vs without GHK-Cu): GHK-Cu-containing skin care products; concentration not reported in the PubMed abstract post-treatment skin regimen (schedule not stated in abstract). These are amounts used in published studies or official labels, not a recommendation.

Q: Where do people discuss GHK-Cu? Is there a GHK-Cu Reddit?

Communities focused on it include r/GHKCuGuide, Finnrick. Experiences shared there aren't evidence, and some allow vendor promotion. All communities.

Non-injectable GHK-Cu (topical etc.) is back in Category 1, so pharmacies may compound it while FDA evaluates. Injectable GHK-Cu was removed from Category 2 in April 2026 and isn't on any allowed list. FDA plans advisory-committee review before the end of February 2027.

Doses studied in research Studied in people

What was given to people (or animals) in published studies and official labels, each linked to its source. This is not a recommendation: study products, purity and supervision differ from research-grade vials.

Who was studied	Dose given	How often	For how long	What happened
adults after CO2 laser resurfacing around the mouth (randomized, skin-care regimen with vs without GHK-Cu) n = 13	GHK-Cu-containing skin care products; concentration not reported in the PubMed abstract topical	post-treatment skin regimen (schedule not stated in abstract)	12 weeks	no objective difference in redness, wrinkles or skin quality vs regimen without GHK-Cu; higher patient-rated satisfaction	PubMed

Animal studies: Mouse studies gave GHK-Cu by intraperitoneal injection at 0.2-20 μg/g (0.2-20 mg/kg) on alternate days in cigarette-smoke lung models, and 0.2 or 2 mg/kg in a smoke-induced muscle wasting model.

The only controlled human study found used a topical cosmetic formulation and does not state its concentration; no human studies of injected GHK-Cu were found. Doses in animal studies do not translate directly to people. Not approved by FDA or EMA as a drug.

What the research says

Some human evidence

Why: Only one small RCT (13 patients, topical after laser resurfacing), which found no objective benefit; everything else is cell and animal work.

Most evidence for GHK-Cu comes from cell-culture and animal studies (wound healing, lung and muscle injury, inflammation models). Controlled human data are very sparse: the only randomized trial among the candidates (13 patients after CO2 laser resurfacing) found no objective benefit, and recent systematic reviews describe GHK-Cu as promising but clinically unproven. Added studies are further cell, animal and review work, plus one uncontrolled human hair study of a multi-ingredient product that cannot be attributed to GHK-Cu.

Systematic evidence-mapping review (no quantitative pooling)

Evidence-mapping review through 2026: preclinical data consistently support matrix remodeling, repair, anti-inflammatory and angiogenic effects, but clinical evidence is sparse and small; a 13-participant post-laser study was negative on objective endpoints. Authors conclude GHK-Cu is 'promising but unproven'.

Key resultA 13-participant post-CO2-laser study was negative on objective endpoints; a 2026 18-participant split-face eyebrow study reported positive cosmetic hair outcomes

Sample
Structured evidence-mapping review; number of studies not stated in abstract
Authors' conclusion
Preclinical data are consistent, but clinical evidence is sparse; until active-entity requirements are met and controlled efficacy shown, GHK-Cu is a promising but unproven therapeutic cargo.
Limitations
No pooling possible; clinical studies small and GHK-Cu speciation poorly defined.

No new data64 records retained from 1,247 screened
Systematic review (PRISMA), qualitative synthesis

Review of 64 records (2005-2026) found a deep preclinical evidence base but thin, fragmented human data, mostly small cosmetic-cream trials, and no adequately powered published RCT of microneedle-delivered GHK-Cu.

Main outcome
Mechanisms and therapeutic applications of GHK-Cu, with focus on microneedle delivery
Authors' conclusion
Preclinical evidence is deep and mechanistically coherent, but human data are thin; well-designed human trials of microneedle-delivered GHK-Cu are needed.
Limitations
Human trials mostly small cosmetic-cream studies; no adequately powered published RCT of microneedle delivery.

Does GHK-Cu work? What does the research say?

Evidence grade B (some human evidence), from 14 papers: Only one small RCT (13 patients, topical after laser resurfacing), which found no objective benefit; everything else is cell and animal work. Most evidence for GHK-Cu comes from cell-culture and animal studies (wound healing, lung and muscle injury, inflammation models). Controlled human data are very sparse: the only randomized trial among the candidates (13 patients after CO2 laser resurfacing) found no objective benefit, and recent systematic reviews describe GHK-Cu as promising but clinically unproven. Added studies are further cell, animal and review work, plus one uncontrolled human hair study of a multi-ingredient product that cannot be attributed to GHK-Cu. See the papers.
