Do you have 100 mcg vials or 1mg (1000mcgs) vials?
If you have 100 mcg vials you can use bac water. In that case i do the whole 100 mcgs using bac water. I inject 50mcgs on one side of my body, usually biceps, then the other 50 mcgs in the other bicep.
If you have 1mg (1000mcgs) vials, then use acetic acid. Inject 1cc right into the vial. Inject it gently and do not shake it. Its a fragile peptide. The acetic acid will burn to inject, so after you withdraw your dose from the vial, then stick your syringe in the bac water vial and mix some bac water with it to dilute the Acetic Acid.
Hope that helps.
