We know IV glutathione has benefits as an antioxidant, but it hasnt been proven in any randomized clinical trials that its safe or effective for skin lightening, says Desai

GHK-Cu contains a chelated copper ion that makes it more oxidation-sensitive than non-metallated peptides like BPC-157

Each spray delivers 300-350mcg of BPC-157 and TB-500 peptides, totaling 30 ml per bottle, ensuring precise dosing for controlled experimental use

Microneedling (0.5 mm for home use) applied before copper peptide serum significantly improves penetration by creating temporary micro-channels through the outer skin barrier

The antioxidant properties help repair muscle damage from exercise and may improve your endurance and overall physical performance

Both together help to boost collagen production to keep skin firm & resilient
