Private Peptide Protocol Workspace
PepStack combines peptide calculators, a browser-first tracker, inventory, and dose timing tools so you can stop juggling sheets, notes, and scattered tabs.

Reconstitution, dosage, syringe, and half-life tools stay close to the peptide data they depend on.
Use the tools without an account, import existing sheets, and sign in only when continuity across devices matters.
Spreadsheet In, Tracker Out
This is one of PepStack's clearest upgrade moments: take the sheet you already manage and turn it into something you can schedule, log, and export again later.
Auto-detect common columns like peptide name, dose, frequency, and timing.
Preview the mapping before anything is written into the tracker.
The tracker starts from the rows you already have instead of forcing a blank setup.
PepStack auto-detects the useful fields, then lets you correct them before import.

Imported rows become a protocol with schedule, logs, and export-ready history.
Private By Default
PepStack should feel practical first, then trustworthy. The privacy story is part of the product, not a legal afterthought buried in the footer.
Read the privacy overviewThe calculation tools run client-side, so routine input values are not posted to your server.
Protocol, dose log, and inventory data are stored in your browser first before any optional account sync.
If you sign in, PepStack can sync tracker records to your private account so you can pick up across devices.
CSV export stays built into the tracker, so the app is not trying to trap your protocol history.
Start Where You Need To
Pick the tool you need right now and there is still a clear path back into the full product.
Create protocols, log doses, manage vials, and review what is scheduled next.
Open the reconstitution, dosage, syringe, and half-life tools without creating an account.
Browse half-lives, dose ranges, and route notes without digging through blog posts.
Learn While You Track
Search is already bringing readers in. The homepage should make those guides feel like part of the product instead of a side archive.
A guide to typical peptide cycle lengths across different categories, why cycling matters, on/off protocols, and how to structure your peptide protocol timing.
A comparison of oral and injectable BPC-157, covering bioavailability differences, the arginine salt form, when to use each route, and what the research shows.
Learn why body weight is critical for accurate peptide dosing and how to calculate the right dose for your weight.
Browser-First, Ready Now
Open calculators without friction, import an existing sheet when you are ready, and create an account only when saving the workflow becomes useful.
