How long will my peptide vial actually last?

Your peptide vial will last based on the size of the vial, how much peptide you use per dose, and how often you take it. To figure this out, you need to know how much peptide is in the vial and how much you're using each time. The amount of water you mix it with doesn't change how many doses are in the vial, it just changes how concentrated the solution is.

Some things to consider when working out doses per vial:

• Vial size
• Amount used per dose
• How often you use it

You get the number of doses by dividing the total amount of peptide by the amount used per dose. That gives you a good idea of how long the vial will last. Getting this right early saves you from either running out sooner than expected or overpaying for water you didn't need.
