Evidence suggests that RGD enhances cell attachment and spreading of osteoblasts onto scaffolds and graft material [140, 141, 159, 188] whilst increasing cellular proliferation and the expression of ALP, Runx2, osteocalcin, osteopontin and bone sialoprotein [141, 142, 146, 190, 191]
The appropriate framing for every outcome discussed above is observed in research models or preclinical/experimental, never demonstrated in humans. Limitations of the Injectable/Systemic GHK-Cu Evidence Several specific limitations constrain what can be concluded, and they compound one another
HUBERMAN: And that you're doing regular blood testing and you're monitoring for any potential tumor growth, et cetera
