When the water is added all the powdered peptide is not dissolving – why?

Once the bacteriostatic or sterile water is added it may take a few minutes for all the powdered peptide to dissolve. Do not shake – this will damage the product, and inject the water slowly at a 45 degree angle to not blast the peptide crystals. Roll the vial in your hands allowing the water to gently move and then let rest for around 15 minutes. This should allow enough time for the water to penetrate the powdered peptide.
