Copper peptides, including both GHK-Cu and AHK-Cu, have a well-established safety profile and are generally well-tolerated by sensitive skin types
The highest concentrations of glutathione exist in the liver, where detoxification primarily takes place
Freezing reconstituted peptide solutions can cause ice crystal formation that damages the peptide chains
Potential risks Serious risks and adverse events include: Allergic reaction to the medications or dye used in the injection Shoulder infection Depigmentation of the skin around the injection site (a whitening of the skin) Local fat atrophy around the injection site (thinning of the skin) Rupture of a tendon located in the path of the injection Nerve damage near the shoulder joint Bleeding at the injection site In addition to the above, corticosteroid injections increase the risk of: High blood pressure High blood sugar Decreased immune function Decrease in bone mineral density Bone infection (osteonecrosis) Reproductive hormone imbalance Metabolic changes (eg, increased appetite, weight gain, and fluid retention) These risks are typically associated with higher doses of corticosteroids, multiple injections, and for people with underlying medical conditions such as diabetes and heart problems
