Curious about the appropriate GHK-Cu dosage as you investigate its potential benefits in areas like bodybuilding, skin repair, and hair growth?

In this guide, we will explain how to calculate an appropriate and effective GHK-Cu dose to administer to test subjects. We will also highlight the main reported benefits of this peptide and illuminate possible avenues for further research.

As a bonus, we will give you our top recommendations for a GHK-Cu vendor—one that ships research-grade GHK-Cu and other peptides worldwide, and another that uses peptides like GHK-Cu in its cosmetic formulations.

Let’s get to it.

What is GHK-Cu?

GHK-Cu is a peptide, or a short chain of amino acids. It is made up of the three amino acids glycine, histidine, and lysine. Together these form GHK, or glycyl-l-histidyl-l-lysine [1].

GHK bonds easily to copper, thereby becoming GHK-Cu. That is why it is also called copper peptide or copper tripeptide. GHK-Cu is produced naturally in our bodies and is found in blood, saliva, and urine.

GHK-Cu seems to play a sizable role in repairing DNA in cells [2]. DNA is essentially a blueprint that cells use when they split and create new cells. When the DNA gets damaged, as is normal over time, that can result in poorer duplication of cells and impaired ability to generate new tissue. GHK-Cu helps repair and reset the DNA, leading to improved tissue growth [2].

When we age, the genes that are involved in inflammation and tissue destruction become more active. The genes that regenerate and repair tissue become less active. GHK-Cu appears to help turn back the clock: it reactivates the regenerative genes and deactivates the inflammatory and destructive ones [2].

GHK-Cu has also been linked to a number of other processes that support tissue creation and has been found to:

  • Stimulate the synthesis of collagen in skin cells [3]
  • Increase the accumulation of protein [3]
  • Increase synthesis of decorin [4]
  • Stimulate the synthesis of metalloproteinases
  • Suppress the production of the inflammatory cytokine interleukin-6 [2]
  • Stimulate antioxidant gene activity [2]

Essentially, GHK-Cu is believed to help the body break down old tissue, repair DNA, and create new, healthier tissue.

Benefits of GHK-Cu?

There are numerous potential benefits associated with GHK-Cu administration. Here is a breakdown of potential benefits reported in the literature:

  • Anti-pain action [1]
  • Anti-anxiety effects [1]
  • Anti-aggression effects [1]
  • Antioxidant protection [1]
  • Repairing wounds [2]
  • Lung and gut tissue healing [2]
  • Hair growth [2]
  • Skin repair, wrinkle reduction, and anti-aging effects [5]
  • Tissue remodeling [6]
  • Antibacterial effects and infection reduction [7]
  • Nerve regeneration [8]

Below, we’ll go deeper into the main potential benefits of GHK-Cu.

GHK-Cu for Anti-Aging/Skin

GHK-Cu is probably best known for its supposed anti-aging properties. It has been well-studied as an anti-aging agent and is considered to be an activator of tissue remodeling. In one animal study, GHK-Cu was found to promote cell proliferation and angiogenesis, thereby accelerating scald wound healing. This research has been used to support its inclusion in many cosmetic products [9].

In one study involving women with sun-damaged skin, GHK-Cu treatment removed visible signs of aging after 12 weeks. It improved skin firmness, elasticity, and clarity as well as reduced wrinkles and fine lines [5]. The peptide showed similar results in a separate clinical trial [10]. It has outperformed products containing vitamin K, vitamin C, and retinoic acid in reducing skin aging [5, 10].
Based on Dr. Loren Pickart’s work, GHK-Cu has been shown to [5]:

  • Tighten skin
  • Improve elasticity and firmness
  • Improve skin density
  • Reduce deep wrinkles and fine lines
  • Reduce hyperpigmentation and sun damage.

GHK-Cu for Healing

GHK-Cu has potential uses as a healing agent. It has not only been shown to help wounds close faster with less chance of infection, but it also seems to be involved in healing ulcers and regenerating lung tissue [1, 2]. It does so by repairing DNA, accelerating tissue growth, and increasing levels of antioxidant enzymes. Separate research has shown that GHK-Cu peptide helps slow down the growth of cancerous tissue and prevent its formation [4, 11].


GHK-Cu for Hair Growth

A number of studies have suggested that GHK may be beneficial for hair growth. Data from these studies indicates that GHK-Cu may increase hair follicle size and thus improve hair growth and thickness [1, 2, 13].
This research suggests that GHK-Cu may be beneficial in subjects suffering from hair loss or hair thinning, clearly highlighting a possible avenue for further research [13].


GHK-Cu for Muscle Growth

There is no published data from human clinical trials to support the notion that GHK-Cu supports muscle growth. However, given that it has been shown to possess antioxidant and anti-inflammatory activity [6], GHK-Cu may decrease recovery time following resistance training. There is a clear need for more research in this area.

Now that we’ve reviewed the main potential benefits of GHK-Cu, let’s now turn our attention to the question at hand: what is the proper way to dose this peptide?


GHK-Cu Dosage Guide | What You MUST Know

Based on the available research, GHK-Cu is considered to be safe and well-tolerated [1]. According to Dr. Pickart, credited with discovering GHK-CU, “no issues have ever arisen during its use as a skin cosmetic or in human wound healing studies” [2].
That said, it is still useful to have a bit of background on the prevalent GHK-Cu dosing protocols.

Minimum effective dose

The lowest known doses of GHK-Cu administered to test subjects involve the application of skin creams and topical ointments. Skin creams containing GHK-Cu are usually applied once or twice a day to affected areas—usually to the face for skin tightening and wrinkles, to the scalp for hair growth, or to other areas for scars or wound healing [10]. When administered in this manner, GHK-Cu appears to be non-toxic and non-irritating with no adverse effects [2].

When injected, there is little data to indicate the minimum effective dose of GHK-Cu [11]. Where GHK-Cu is sold as a powder that is reconstituted for injection, a typical starting dose is 1 mg per day over a treatment course.

Effective dose

The effective dose of GHK-CU depends on the route of administration, whether that is via injection, a topical cream, or tablet.

CHK-Cu injections

Subcutaneous injections are a common way to administer GHK-Cu to test subjects for the purpose of studying systemic healing, skin rejuvenation, and hair growth.
Researchers and anti-aging doctors typically administer 1-2 mg/daily of GHK-Cu over the course of a 30-day treatment.

Skin creams and skin patches

GHK-Cu skin creams and patches seem to be able to pass therapeutically effective amounts of this copper peptide through the skin and into the body [14].

  • 0.5 micrograms/kg seems to be effective as a daily dose for lowering anxiety. That would be 35 μgs for a 70kg person [15].
  • 50 mg seems to be effective as a person’s daily dose for systemic healing [11].

Of course, topicals may vary in their formulas and exact GHK-Cu content, so it is always prudent to read the instructions for the product you’re using and consult your physician as necessary.

Liposomal encapsulated oral tablets

There is no evidence that administering GHK-Cu in regular pill form produces any effects, as it is broken down in the intestines. However, research indicates that liposomal encapsulated tablets may be effective when dosed at 10 mg per day or more [11].

Lethal dose

GHK can lower blood pressure, so a large enough dose may have serious consequences. However, the lethal dose of GHK-Cu peptide is very high—it would be about 21,000 mg for a 70kg human (or about 330 mg/kg) [13].

Recommended dose

As a research peptide, there is no “recommended dose” for GHK-Cu. However, a review of the available literature suggests that researchers can dose it in the following way [2]:

  • GHK-Cu Dose: 1-2 mg per day, injected subcutaneously or intramuscularly.
  • Frequency: Once per day. You can also split the dose into several smaller injections.
  • Duration of Cycle: 30 days.

We do not encourage the unsupervised self-administration of GHK-Cu or any other research peptide—under any circumstances.
