To be clear up front: Koi Peptides sells research-grade, sterile lyophilized GHK-Cu powder for in vitro laboratory study only

Tap the syringe lightly with your finger to remove any air bubbles.Push the air out of the syringe by pushing the plunger all the way down
Deficiency creates a bottleneck in this process that manifests as fatigue, low motivation, and poor exercise recovery
Epidemiology: High levels of vitamin B12 were found in: Causes: Excessive supplementation (a direct increase in plasma vitamin B12 by excess intake or administration) Increased release of vitamin B12 from tissue stores (liberation from an internal reservoir): Solid tumors (especially hepatic or hematologic malignancies) Liver metastases Increased binding proteins: 7 Excess production: Liver disease (e.g., hepatitis, cirrhosis, hepatocellular carcinoma) damaged hepatocytes release haptocorrin (transcobalamin I) and B12 into circulation Myeloproliferative disorders these increase granulocyte production, which leads to more haptocorrin (transcobalamin I/III), a B12-binding protein produced by proliferating myeloid cells
