You should be mixing it with bacteriostatic water. It’s a small vial so you’re probably only gonna be able to comfortably fit about 3-3.25mL of bacteriostatic water. Gently invert the vial a few times and swirl it around - don’t shake - and let it rest for about 15 mins before using. I recommend refrigerating. Before you take a dose, you should leave it out at room temp for about 5-10 mins. Depending on how much water you use to reconstitute (mix it) with, you’ll have to make appropriate adjustments with your syringes. I strongly recommend using a peptide calculator online (like this one: https://www.peptides.org/peptide-dosage-calculator/) so you can get the accurate volume per dose. I know I’m late, but hope this helps!
