A peptide vial label shows: the peptide name, the strength (usually in mg), a lot number, and sometimes an expiration for the powder. The strength is the total amount of peptide inside, not the dose. Your dose is a fraction of the total, measured in mcg (micrograms). Confirm the strength before you calculate anything.
