Good morning. I'm new here, and this will be my first time using GHK and Tirz, so I'm unsure about how much bac water I should buy. What quantity do you recommend I purchase?
Take the amount in the vial and multiply with how much you want to draw out on the syringe 1 unit is 0.01ml so 0.1ml is 10units etc. and then divide with how much you want said dosage to be
Example
30(mg) * 0.15 (15 units) / 4 (mg)
