You will know what I mean right when you walk in the door

Check your maths before drawing up

Add 1,000 L (1 mL) of reconstitution solvent to the 1 mg vial This yields a 1 mg/mL (1,000 g/mL) stock solution To achieve 100 g/mL working stock: Dilute 100 L of 1 mg/mL stock into 900 L of PBS or cell culture medium yields 100 g/mL in 1 mL To achieve 10 ng/mL in a 5 mL experiment: Take 0.5 L of 100 g/mL working stock + 4,999.5 L of medium Alternatively: dilute to an intermediate concentration to reduce pipetting error Use a dilution series approach (stock working stock final experimental concentration) to minimize pipetting inaccuracy at nanogram-level concentrations

A 7.5 mg dose becomes exactly 100 units, which is a full 1 mL syringe

We mention this not to claim GHK-Cu is "better" than retinol - it isn't a fair comparison given the difference in research depth - but because it suggests the ingredient is doing something real at the structural level when formulated and applied thoughtfully
