@AdinaFloyd it’s Calcium Chloride a PRP activator you will need to mix to the plasma. Make sure you mix it! I usually take syringe (3ml) get 4 drops of Calcium Chloride into syringe then fill it with plasma, and mix it! I use syringe adaptor to mix it well! Some do it without Calcium Chloride. I think it just make it more effective.
