Frequently Asked Questions
Should I inject GHK-Cu or use it topically?
Both routes work. Topical application (in serums/creams) is popular for facial skin rejuvenation. Subcutaneous injection provides systemic benefits and may be better for hair regrowth and whole-body effects.
How long until GHK-Cu shows results?
Skin improvements may be visible within 2-4 weeks of consistent use. Hair regrowth, if it occurs, typically takes 3-6 months to become noticeable.
Can GHK-Cu help with hair loss?
Research suggests GHK-Cu may help by enlarging hair follicles, increasing follicle size, and stimulating hair growth. Results vary by individual and cause of hair loss.
Is GHK-Cu safe for long-term use?
GHK-Cu has an excellent safety profile in studies. It's naturally present in the body, and supplementation appears well-tolerated. However, long-term human studies are limited.
Research Summary
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human plasma, saliva, and urine that decreases with age. Research has demonstrated GHK-Cu's remarkable ability to stimulate collagen and elastin synthesis, promote wound healing, and reduce inflammation. It activates over 4,000 genes, with many involved in tissue remodeling and repair. Studies show it increases antioxidant enzymes, reduces scarring, and may reverse some aspects of skin aging. GHK-Cu is unique in that it can be used both topically (in skincare) and via injection for systemic effects. It's one of the most studied peptides for anti-aging applications.
