Track supply in the protocol workspace
PepStack keeps remaining stock and upcoming doses on the same screen so you can see operational risk early.
- Protocol-linked inventory
- Next-dose context
- Lower manual counting overhead
Inventory
A peptide inventory manager that shows remaining supply before the schedule breaks.
PepStack keeps vial counts, remaining doses, and low-stock context tied to the protocol using them, so supply is part of the routine instead of a separate spreadsheet.
Low-stock visibilityVial trackingProtocol contextExportable records
See low stock next to the protocol that will consume it.
Catch expiring or nearly empty vials earlier.
Keep supply and schedule in one private workspace.

Why peptide inventory usually becomes a second spreadsheet
Inventory gets split out when the main tracker cannot answer simple questions like what is low, what expires soon, and what protocol will run out first.
Surface low and aging supply
The inventory view makes low-stock, expired, and expiring-soon items visible without opening every vial card individually.
- Low-stock status
- Expired state
- Expiring-soon visibility
Stay portable when needed
Import existing rows and keep export available, so inventory tracking gets better without turning into lock-in.
- CSV import
- Exportable history
- Local-first records
Comparison
Inventory manager vs separate stock sheet
The main difference is whether supply remains connected to the schedule that uses it.

Workflow
How PepStack handles peptide inventory
The inventory layer works best when it sits next to dose timing and protocol history, not in a disconnected admin tab.
1
Create or import the protocol and supply
Start with your current vials, pens, or CSV rows instead of rebuilding the whole setup.
2
Let the tracker expose low-stock risk
PepStack keeps upcoming doses and remaining supply in the same workflow.
3
Review aging stock before it becomes a surprise
Use inventory status to catch expired or nearly-empty supply earlier.

FAQ
Common questions
PepStack is an informational tracking tool only. Always follow the storage and handling instructions provided by your clinician or pharmacy for prescription compounds.
Can PepStack track peptide vials and remaining doses?
Yes. Inventory tracking is built into the tracker so remaining supply is visible alongside the protocol that uses it.
Does it warn about low stock or expired supply?
Yes. The inventory view surfaces low, expired, and expiring-soon items directly instead of hiding them inside separate notes.
Can I import an existing peptide stock spreadsheet?
Yes. CSV import remains available so you can move current rows into the tracker without starting over.

Use the tools first, then keep the workflow when it becomes useful.
PepStack works best when the calculator, tracker, and import path feel like one product instead of separate tabs.
