The potential of GHK as an anti aging peptide Dou Aging Pathobiology and Therapeutics The tripeptide GHKCu complex ameliorates lipopolysaccharideinduced acute lung injury in mice Oncotarget Nitrite reverses nitroglycerin tolerance via repletion of a nitrodilator activated nitric oxide store in vascular smooth muscle cells ScienceDirect Peptides stimulate growth hormone and IGF 1 production, promoting angiogenesis and cellular proliferation. In patients with undetected cancers, these peptides can accelerate tumor growth. Conventional imaging misses early cancers. Circulating tumor The tripeptide GHKCu complex ameliorates lipopolysaccharideinduced acute lung injury in mice Oncotarget Not too big. Not too small. Because of their intermediate size, macrocyclic peptides combine the potency and precise targeting of an antibody or biologic therapy with the stability and ease of administration of a
