What Is GHK-Cu?
GHK-Cu is a naturally occurring tripeptide (Gly-His-Lys) bound to a copper ion. Key research areas:
- •Wound healing: Studied for accelerating tissue repair and reducing scarring
- •Collagen synthesis: Research shows upregulation of collagen production
- •Anti-inflammatory: Demonstrated reduction of inflammatory markers in studies
- •Hair growth: Investigated for follicle stimulation
- •Anti-aging: One of the most-studied peptides for skin rejuvenation mechanisms
Molecular Details
- •Sequence: Glycyl-L-histidyl-L-lysine:copper(II)
- •Molecular Weight: 403.93 Da
- •Form: Typically sold as lyophilized powder (blue-tinged due to copper)
What to Look For When Buying GHK-Cu
Purity Verification
GHK-Cu is a simple tripeptide, so most vendors can source it at high purity (98%+). The copper complexation is the key quality factor — verify the COA confirms proper Cu²⁺ binding.
Form Factor
GHK-Cu is available in several forms:
- •Lyophilized powder — Standard research form, longest shelf life
- •Topical/cream — Some vendors sell GHK-Cu in topical formulations
- •Solution — Pre-mixed for convenience
For research applications, lyophilized powder offers the most flexibility and stability.
Best Value for GHK-Cu
At $0.26/mg, Paradigm Peptides offers the best price with Finnrick A verification. For a balance of price and established reputation, Swiss Chems and Pure Rawz are solid mid-range options.
The unusually large price range ($0.26-$0.96/mg) makes comparison shopping particularly valuable for GHK-Cu.
