Plan & organize
Start with what you have. Keep the details that matter.
Create
Vial label maker
Make a research inventory label. Use “Make label” beside a vial listing to fill in its vendor, compound and labeled content.
Check the lot against the report before adding its URL. An indexed vendor report may cover a different batch. A QR link does not certify the contents.

Enter a compound and labeled content to preview your label.
Generated on your device. Print at 100% / actual size with margins and headers off; scan the QR on a test print. The date is your record date, not an expiry date.
Plan
Stockpile planner
See how long your current inventory covers the amounts you enter, then compare the additional amount you need.
Your supply at a glance
Enter a whole number of vials (zero is OK), positive mg per vial, amount per use, uses per week and target weeks.
Saved on this browser. Inventory math only; no suggested amounts. Assumes all labeled content is usable across vials, with no waste, loss or expiry. Coverage is approximate; a fractional weekly schedule is averaged. Comparing replaces this compound's amount in the Shopping Planner and selects vials.

Convert
Unit converter
- 1 mg
- 1,000 mcg
- 0.001 g
On a U-100 insulin syringe, 10 units = 0.1 mL; on U-40, 10 units = 0.25 mL. IU can't be converted to mg without the compound's own factor (somatropin: about 3 IU per mg).
