Use of a cAMP BRET sensor to characterize a novel regulation of cAMP by the sphingosine 1-phosphate/G13 pathway
It is known that endogenous levels of GHK peptide naturally decline with age, from roughly 200 ng/ml at age 20 to 80 ng/ml at age 60 [3], and studies have shown that GHK-Cu can reset gene expression of human cells to a healthier state, which has led to breakthroughs in tissue regeneration and wound healing [4, 5, 6]
Still, doctors are careful if youve had it before
These spread the cost of visits, labs, and sometimes medication over several months
