high dose ghk cu Peptide Injection and GHK immunogenicity of ghk-cu or antibodies

Serum limitation-induced senescent fibroblasts model and effect of FOXO4-DRI Passage 3 fibroblasts derived from keloids and normal skins were cultured in a Dulbeccos Modified Eagles medium (DMEM, Hyclone, Logan, Utah, USA) containing 10% fetal bovine serum (FBS, Gibco, Grand Island, NY, USA) to 90% confluence, and then cultured in a DMEM containing 2% FBS for 3 days to construct a serum limitation-induced senescent fibroblast model

ive used it for 4 weeks now and the difference is major

But the evidence these claims come from involves copper levels way higher than youd ever get from a serum
