GHK-Cu questions
Answers are arithmetic only. Vialwise does not give dosing advice.
How much bacteriostatic water do I add to 50 mg of GHK-Cu?
There’s no single correct amount. The water only sets the strength: more water means less GHK-Cu in each unit, which makes small doses easier to measure. With a 50 mg vial, 1 mL gives 50 mg/mL, 2 mL gives 25 mg/mL and 3 mL gives 16.67 mg/mL. Make sure the amount fits in your vial.
How much GHK-Cu is in 10 units?
10 units on a U-100 insulin syringe is 0.1 mL. With 50 mg mixed in 2 mL, 10 units holds 2.5 mg. Mixed in 3 mL, it holds 1.67 mg.
How many clicks is that on a peptide pen?
On a standard peptide pen one click is 0.01 mL, the same as one unit on an insulin syringe. With 50 mg in 3 mL, each click holds 166.7 mcg. A 3 mL cartridge holds 300 clicks.
Which syringe should I use?
Pick the smallest insulin syringe your dose fits in. A 0.3 mL syringe holds 30 units, 0.5 mL holds 50 and 1 mL holds 100, usually marked every 2 units. Smaller barrels spread the marks out, so small doses are easier to read.
