Step 5: Label and Refrigerate Standard practice labels the vial with reconstitution date and concentration (40mg/mL) and refrigerates immediately at 36-46F (2-8C)
Structurally a close cousin of GHK-Cu, AHK-Cu has become a focused subject of preclinical investigation, particularly in studies relating to hair follicle biology, dermal cell research, and copper-mediated signalling pathways
This mechanism is supported by peer-reviewed research, including studies by Khavinson and colleagues published in gerontology journals, confirming its biological effects
Key Takeaways The conservative answer is about 28 days in the refrigerator
found that creams containing GHK-Cu significantly improved skin firmness, density, laxity, and wrinkle reduction around the eyes and face
