I think they were talking about the creams/topical applications
“When evaluating a GHK-Cu topical product, watch for these warning signs:
Ingredient Conflicts:
Vitamin C (Ascorbic Acid): Highly acidic (pH 2-3), will destabilize GHK-Cu and cause copper precipitation
AHAs/BHAs: Lower pH, disrupt copper binding
Retinoids: Oxidize easily, compete for penetration pathways
High concentrations of preservatives: Can chelate copper away from GHK
Wrong pH:
Products formulated below pH 5.0 or above pH 7.5 will have rapid degradation
If the product stings or burns, it’s likely outside the stable pH range
Poor Packaging:
Clear or translucent bottles: Allows UV degradation
Dropper bottles without airless pumps: Allows oxygen exposure
Large bottles (>30mL) without preservatives: Microbial contamination risk
Misleading Claims:
“10% GHK-Cu”: This concentration is extremely rare and expensive. Most products labeled as “10%” are actually 10% of a diluted GHK-Cu solution (often 0.5-1% actual peptide)
“Instant results”: GHK-Cu works at the genetic level—visible changes take 4-8 weeks minimum
“No refrigeration needed”: Simple aqueous GHK-Cu solutions degrade rapidly at room temperature”
The section that talks about sub q injection doesn’t reference stinging at all.
Systemic Healing (Injectable/Subcutaneous)
“When administered subcutaneously (typically at 1-5mg per injection), GHK-Cu can produce systemic effects:
Enhanced wound healing post-surgery or injury
Reduction in systemic inflammation markers (CRP, IL-6)
Improved lung health and protection against oxidative damage (studied in COPD models)
Potential neuroprotective effects (under investigation)
Support for tissue remodeling after trauma”
I’ve never injected GHK-cu without at least a little bit of a sting/red irritation either. Everything I’ve read has said that is completely normal for the injectable form.
