The % of active is a % of the whole. Calculate it from the volume of serum.Merk1986 said:I have a 10mg vial of Snap 8 on order along with raw GHK-CU. Completely new to this and would like to start blending my own serums. When you suggest 3% how do you determine that ratio? Can you recommend a base for the serum? Am thinking Ordinary's Hyaluronic Acid 2%. Any pointers would be very much appreciated! My math and chemistry skills are lacking
