Most people can tell you what they paid for a vial and not what day they mixed it
— which is the one number that decides whether the rest was wasted. Print these, write it down
once, stop guessing. Free, no signup, nothing stored.
Tip: on a phone, tap Print and choose "Save as PDF".
Plain paper and sticky tape works; address-label sheets work better.
What to write, and why
Mixed on — the single most useful field. Everything else is guesswork
without it.
Discard after — work it out once when you write the label rather than
trying to remember the rule later.
Strength and diluent — so a vial you come back to in three weeks still
makes sense.
Store — circle it, because the vial that ends up in the wrong place is the
one that gets ruined.
Never write it down at all?
Peptide Wizard tracks the mix date for you, counts the doses left in each vial, and warns you
before one reaches the end of its window. The labels are for the fridge; the app is for
everything else.
