How does the inventory tracker know what I have?

You tell it: add each item with the amount you have and its unit. After that, every change is a line in its history: logged entries, adjustments and recounts.

Can it take amounts off automatically?

Yes, when “Take logged amounts off” is on. A taken entry with the same name comes off when the units match (the same unit, or mg and mcg). Items counted as pens or vials lose one per entry. Editing or deleting the entry gives it back.

What if my count doesn’t match the tracker?

Use Adjust with a reason such as “recount”. The history keeps both the logged entries and the correction, so you can see where the difference came from.

Does it work out concentrations or how long a vial lasts?

No. It doesn’t convert between a vial’s contents and a volume, and it doesn’t predict run-out dates. Use a calculator for concentration math.

Peptide inventory tracker

Record what you have once, then let every change write a line: entries you log, recounts, new deliveries. The remaining amount is always the opening amount plus its history, so you can check it.

Your inventory

How stock changes. You enter how much you have. With “Take logged amounts off” on, each taken entry with the same name comes off the remaining amount when the units match: the same unit, or mg and mcg (1 mg = 1,000 mcg). IU and ml only come off items counted in IU or ml. An item counted in whole containers (count: single-dose pens or vials) loses one per taken entry. Stock never goes below 0, and editing or deleting an entry gives its amount back. Nothing here converts between a vial’s contents and a volume; for concentration math use the Peptide Library calculator.

Everything here is the same record as the full tracker, stored in this browser only. Export or back it up from its Data tab.

The ledger method

Add the item with the amount you have and its unit: mg, mcg, IU, ml, or a count of whole pens or vials.
Every change is a new line: when, what happened, the change and what’s left.
Never overwrite the remaining amount without a line saying why; that line is what makes the number checkable.

Every change is its own line, so the remaining amount can always be checked. Example values in mg.

Counting pens and vials

For single-dose pens or vials, choose “count” as the unit and leave “Take logged amounts off” on: each taken entry with the same name removes one. For a container that holds several uses, count containers with automatic deduction off, and use Adjust (“new pen started”) when you open the next one.

Expiry and disposal

Put expiry dates in the item’s notes and archive items you no longer use, which keeps their history. For disposing of unused or expired products, see the FDA’s guidance: Disposal of Unused Medicines and Don’t Be Tempted to Use Expired Medicines.

Inventory and the log together

Inventory takes amounts off by name, so use the same name in the log as in inventory. The Data tab of the full tracker exports items with their starting and current amounts.

When you want run-out dates and reorder reminders worked out for you, Peptide Library’s inventory tracker does that across devices.
