This gives a concentration of 50 mg per ml , which works out to 0.5 mg per unit on a 1 ml insulin syringe

For doses of 10 units or less , a 30- or 50-unit insulin syringe improves readability

Ligand-independent dimerization of the extracellular domain of the leptin receptor and determination of the stoichiometry of leptin binding

You had plenty of it in your 20s

The dose is deliberately high compared to classical peptides (5-10 mg for GLP-1 analogues, 2-5 mg for short regeneratives) because documented GHK-Cu protocols use larger quantities in trichological and cutaneous research (1-3 mg per injection, concentrated topical applications)
