When in doubt, consult qualified healthcare providers familiar with peptide research

IGF-1/IGF-1R induces differentiation rather than proliferation when the cells do not express or underexpress insulin receptor substrate-1 (IRS-1), a docking protein for both IGF-1R and the insulin receptor that is known to send a mitogenic, anti-apoptotic and anti-differentiation signal 35,36

Copper is a cofactor for lysyl oxidase (the enzyme that crosslinks collagen and elastin), superoxide dismutase (a critical antioxidant enzyme), and numerous other copper-dependent enzymes involved in tissue maintenance

Cysteine is a key component of glutathione

In contrast, TIGAR overexpression or treatment with Fer-1, a ferroptosis inhibitor, significantly increases NADPH, GPX4, and GSH levels, reduces GSSG expression, and attenuates neuronal ferroptosis and neurological impairment
