Guide
A spreadsheet of what you bought stops being true the first time you dose. The inventory worth keeping is the one that subtracts as you log, tells you the date you run out, and knows which vial a protocol is drawing from.
This is the step people skip and then wonder why the numbers never move. A vial sitting in a list is just a note; a vial attached to a protocol is a vial the app can subtract from every time you log a dose. Once linked, remaining amount, doses left and days of supply all maintain themselves.
It is also what makes cost reporting possible at all — without the link, the app has no way to know which doses drew from which purchase.
“1.3 mL remaining” makes you do arithmetic. “5 doses left, out on the 19th” is the number you act on, and it is the one that should drive a reorder. Work it back from your supplier's shipping time: if delivery is ten days, a warning at five days' supply is already too late.
Set the low-stock threshold in days rather than as a percentage. A percentage means something different on a 5 mg vial than a 50 mg one.
Sooner or later a dose is larger than what is left in the open vial and you draw the rest from the next one. An inventory that cannot represent that will either refuse the dose or silently gift you stock. Both are wrong, and the second is worse because it is invisible. Check that whatever you use handles it — and that undoing such a dose puts both halves back.
Lyophilised powder keeps for a long time; a reconstituted vial does not. Record the date you mixed it, not just the date you bought it, and keep the storage note with the vial. The compound reference pages carry the usual storage and reconstitution guidance for each compound.
Cost per vial is not cost per dose, and cost per dose is the figure that lets you compare suppliers or decide whether a protocol is worth continuing. It falls out of three numbers: what the vial cost, how much is in it, and your dose. The vial cost calculator does it in the browser; the app does it across every vial you own and totals it per month and per compound.
If your supplier provides a certificate of analysis, store it against the specific vial and lot rather than in a downloads folder. A COA that you cannot match to the vial in your fridge is not much use, and vendor pages get taken down — keep the file and the link.
Yes, and it calls them bottles rather than vials. The total is worked out from the count and the strength you entered.
IU stock stays in IU. There is no universal IU-to-mg conversion, so the app never invents one — and a refused conversion is never treated as zero stock, which is a bug we have already had and fixed.
Yes. The app opens them in order, and a dose that spans the end of one and the start of the next is handled as one dose across both.
Yes — unlimited vials, runway and low-stock warnings are all on the free tier. Cost reports and certificates of analysis are Pro.
