The catch is that it fades with age: blood levels sit around 200 ng/mL at age 20 and drop to roughly 80 ng/mL by age 60 , and that decline lines up with the body's slower repair as we get older.[2] It was discovered in 1973 by researcher Loren Pickart, who found that something in human blood made aged liver tissue behave like younger tissue again that "something" turned out to be GHK.[1] What does GHK-Cu do
administration of the experimental compounds (MK-801, GLP-1, GLP-1MK-801 (all at doses of 100 nmol kg 1 ), semaglutide (10 nmol kg 1 ) or isotonic saline as vehicle)
This deletion abolishes IGFBP binding while preserving IGF-1R affinity, making DES locally hyperactive but highly labile (half-life of a few minutes)
