GHK-Cu Peptide and Hair Follicle Growth

by Dr. Usman | Feb 21, 2021 | Research

The GHK-Cu peptide has been speculated to reduce the formation of DHT in hair follicles. There appear to be two forms in which the 5-alpha reductase exists: Type 1 which plays a role in the hair follicles and Type 2 which plays a role in the prostate tissue. 5-alpha Reductase appears to be inhibited by the pro-pecia (finasteride), thereby improving follicle growth. Although the pro-pecia appears to be more significant for the Type 2 forms, it may control the enlargement of the prostate. In context to the Type 1 5-AR, they appear to be better inhibited by the increasing copper ions in skin cells, thereby controlling the damage to the hair growth. As per the research conducted by the different researchers, copper ions in the may potentially inhibit the Type 1 5-AR by up to 90%. It is also suggested that Type 2 form may be less efficiently inhibited by copper ions. Hence, it can be hypothesized that the 5-AR may be specifically inhibited by copper ions.

Iron Toxicity and GHK-Cu Peptide

After significant caloric ingestion, levels of iron appear to increase, thereby saturating Transferrin. The excessive iron may circulate as free iron in the blood and may be toxic upon direct exposure for the target organs. The Ferritin may release the GHK-Cu (2+) reduced iron by 87%. Approximately, 4500 atoms of iron per protein molecules may be stored in Ferritin, considered to be a catalyst of the lipid peroxidation, thereby producing a slew of free radicals, resulting in the damage of cell membrane, protein and DNA. The entry of free iron in the cells and its accumulation in the mitochondria may disrupt the process of oxidative phosphorylation, may catalyse the lipid peroxidation forming free radicals and hence, may cause cell death.

Cell proliferation and Tissue Repair

Research conducted by different scientists has suggested that the miR-399-5p expression may be downregulated by GHK. In the cells, the anti-apoptotic potential of GHK appears to be partially reversed due to the overexpression of miR-399-5p. The research also suggests that the downregulation of miR-339-5p speculated to be induced by GHK may involve the p38 MAPK pathways. The miR-399-5p/ VEGFA have also been hypothesized to play a role in the prevention of neuronal apoptosis as a consequence of the ICH injury. In the cells, the miR-399-5p expression may possibly be downregulated by GHK and the miR-399-5p appears overexpressed, which may reverse any anti-apoptotic potential of GHK.

GHK-Cu and Inflammation Studies

GHK has been isolated in urine, saliva and plasma. It occurs naturally, and appears to form complexes with copper readily, and may regulate the metabolism of the copper. The copper (II) chelation and the GHK tripeptide, together form the GHK-Cu, may accelerate the processes of wound healing, regeneration, anti-inflammatory actions and anti-oxidant potential. The level of the TNF-α and TGF-β, the acute phase inflammatory cytokines, may be lowered following GHK-Cu exposure, thereby resulting in the oxidative damage and hence, the suppression of inflammation.

In one research study, it was suggested that the GHK-Cu exposure to the animal models increased the superoxide dismutase and decreased the production of the reactive oxygen species. Also the production of IL-6 and TNF-α appeared to be decreased as a result of the suppression of the p39 MAPK and NF-κB p65 in the in-vitro model. The results of the studies have suggested that the LPS-induced phosphorylation of NF- κB p65 may be also inhibited by GHK-Cu. Additional studies have reported that the GHK-Cu may potentially inhibit the NF-κB pathway in inflammatory bowel diseases and chronic inflammatory diseases.

With all these points, it has been suggested by researchers that the GHK-Cu has the potential to improve the growth of hair follicles, as it appears to reduce the negative impacts such as inflammation and iron toxicity, and may promote processes such as cell proliferation and blood circulation close to the site of follicle development.

Can GHK-Cu be used with other active ingredients like Vitamin C or Retinol?

  1. 01Yes, GHK-Cu is generally compatible with many other active ingredients. However, we advise applying GHK-Cu first, allowing it to absorb, before applying stronger actives like high-concentration Vitamin C or Retinol. This approach helps minimize pote…

01What If I Store Reconstituted GHK-Cu Incorrectly — Does Copper Dissociate?

Yes. Copper coordination is pH-sensitive and temperature-dependent. Store reconstituted GHK-Cu at 2–8°C in bacteriostatic water at neutral pH (6.5–7.5) to maintain copper-peptide stability. Exposure to temperatures above 25°C or acidic pH below 5.0 can cause copper dissociation, leaving inactive GHK without its essential cofactor. Once copper dissociates, the peptide loses its MMP-modulating and anti-inflammatory activity. Freeze-thaw cycles also degrade copper coordination. Aliquot into single-use vials if storing long-term at −20°C.

02What If I Can't Afford the Full Lab Panel — What's the Minimum?

If budget limits testing, prioritize these three: hs-CRP (inflammation tracking), serum copper (toxicity monitoring), and ALT (hepatic safety). Those three markers capture the most critical safety and efficacy signals. You lose granularity without the full panel. You won't know if ceruloplasmin adapted appropriately to copper load, you won't catch early kidney function changes. But those three tests prevent the most serious protocol risks (copper toxicity, liver dysfunction, missing inflammation trends). Retest all three at week 8 minimum.

03What If I Use GHK-Cu With Retinoids — Will They Interfere?

No direct antagonism exists between GHK-Cu and retinoids. Apply retinoid at night and GHK-Cu in the morning to avoid potential pH conflicts (retinoids work best at pH 5.5–6.0; GHK-Cu at 5.0–6.5). Some users report reduced retinoid irritation when alternating with GHK-Cu, likely due to GHK-Cu's anti-inflammatory effects suppressing the NF-κB pathway that retinoids can activate. If combining both in a single routine, introduce one at a time over 4–6 weeks to isolate tolerance.

04What If I'm Using GHK-Cu in a Multi-Peptide Stack?

Calculate each peptide's concentration independently and use separate syringes for each draw. Mixing reconstituted peptides in the same syringe barrel before injection. A shortcut some researchers attempt to reduce injection count. Risks peptide-peptide interactions that alter bioavailability or cause precipitation. GHK-Cu's copper ion can chelate with other peptides containing histidine or cysteine residues, forming inactive complexes. Draw and inject each peptide separately, even if they're administered at the same anatomical site.

05What If I See No Results After 8 Weeks?

Check preparation and storage first. GHK-Cu degrades rapidly if stored above 4°C or exposed to light. If the solution has turned brown or cloudy, oxidation has inactivated the copper-binding site. Second, verify concentration. Formulations below 0.5% copper peptide lack sufficient bioavailable copper to activate lysyl oxidase. Third, assess penetration. If you're applying to damp hair rather than directly to dry scalp, the peptide never reaches the dermal layer. Most preparation errors eliminate efficacy entirely, which is why we emphasize precision in peptide sourcing and handling across our full peptide collection.
