Illustrative organizational example. The remaining amount is represented from entries, not independently measured.

PeptideGrid keeps user-entered supply, batch IDs, recorded balances, dates, documents, and linked records together in one history. The remaining amount is represented from your entries. PeptideGrid does not measure vial contents or decide treatment, dosing, or what to use next.

Basic inventory on Free · no payment details required

One supply should not live in four places.

A batch ID on packaging, a running total in a spreadsheet, a reminder that only knows the time, and the actual record in another note make the same supply hard to reconstruct. PeptideGrid keeps the batch, the recorded event, the inventory change, and the history on one trail.

  4. History

Follow one batch through the history that stays with it.

Adding a vial is the start of a ledger, not a cell you will overwrite later. Compatible records, represented balance changes, and later corrections remain attached to that batch so you can reopen what happened.

    User-provided label, batch ID, and starting amount stay with this supply.

    A compatible recorded event keeps this vial beside the history it belongs to.

    Each linked event adds an inventory change. The remaining amount updates from those entries.

    A correction keeps its note and context instead of silently overwriting the previous number.

    The represented remaining amount, earlier changes, and linked records stay available to reopen.

What stays with the batch.

Inventory is the workspace for physical supplies. Records remain the history of what happened. A dose can connect to a batch without turning those two areas into the same object.

Three tools, three different questions.

Use the calculator when you need concentration or syringe markings. Use the supply calculator when you want a projection from values you already have. Use inventory when you need the ongoing record of the vials themselves.

  • Reconstitution Calculator

    Concentration, exact volume, and syringe markings from vial, diluent, and target values you provide.

    Open the reconstitution calculator
  • Vial Supply Calculator

    Projected schedule coverage from a supply amount and timing you already have. A one-time projection, not a live balance.

    Open the vial supply calculator
  • Inventory Tracker

    Ongoing record of individual supplies, batches, recorded changes, documents, and the history attached to them.

A spreadsheet can hold a number. It rarely keeps the trail.

PeptideGrid does not replace every sheet. It improves the part that usually breaks: connecting a batch to the recorded event that changed it, and keeping that change reviewable.

Inventory sits beside the records that used it

A recorded balance is not a measurement.

PeptideGrid organizes the supply information you enter. It does not independently inspect a vial or decide what should happen next.

What PeptideGrid records

  • User-provided labels, batch IDs, and starting amounts
  • Represented remaining amounts derived from your entries
  • Linked recorded events and inventory-change history
  • User-entered dates and private document references

What PeptideGrid does not determine

  • How much is physically left in a vial
  • Authenticity, purity, safety, or usability
  • Treatment, dosing, or what you should inject
  • When to reorder, refill, or buy another supply

Inventory questions, answered plainly.

These answers stay inside the product boundary: recorded information, represented balances, and no treatment decisions.

What is a peptide inventory tracker?
A peptide inventory tracker keeps user-entered supply details — vial or batch labels, batch IDs, recorded balances, dates, documents, and linked records — together as an ongoing history. PeptideGrid does this beside the records that used each batch. It does not measure what is physically left or decide what to use.
Can I keep separate vial or batch records?
Yes. Each batch is one physical supply you choose to track, with its own label, recorded balance, and history. Compatible records can link to a batch without merging separate supplies into one total.
Does PeptideGrid know exactly how much is physically left?
No. The remaining amount is a represented balance based on the starting quantity, recorded events, and adjustments you enter. PeptideGrid does not independently measure vial contents.
How is this different from the Vial Supply Calculator?
The Vial Supply Calculator answers a one-time projection: how far a user-provided supply may last on a schedule you enter. The inventory tracker is the ongoing record of individual batches, recorded changes, and linked history. A projection is not the same as a recorded balance.
Does PeptideGrid decide when I should reorder?
No. Inventory may note that a recorded balance looks low based on a threshold you set. That is organizational context, not a purchase, refill, or treatment recommendation.
Is inventory available on the Free plan?
Yes. Free includes basic inventory, batches, and essential warnings for 1 active plan. Premium adds deeper organization and inventory visibility across up to 10 active plans. Core tracking, corrections, export, and deletion stay available on every plan.

Keep the next vial with the history that belongs to it.

Start with one batch and the amount you already know. Link recorded events as they happen. The represented balance and the change history stay together.

Organizational and educational tools only. No diagnosis, prescribing, or dose recommendations.
