One of the most common questions from people managing a peptide or injectable protocol: how many vials do I actually need? Here's a simple way to think about it — using your own protocol details, not ours.
The Basic Formula
Total vials = (Amount used per session × Number of sessions) ÷ Amount per vial
Your healthcare provider will give you the specifics for your protocol. Once you have those numbers, plug them into our Vial Case Calculator to find the right case size.
Running Multiple Compounds
Managing more than one injectable? Add up the vial counts for each compound. Most multi-compound protocols land in the 10–30 vial range, depending on duration and frequency — but your provider will know best.
Choosing the Right Case Size
Once you have your vial count, here's a rough guide for picking a case:
- 1–4 vials — Travel Cases (compact, pocket-friendly)
- 5–12 vials — Small Essential or Vial Vault cases
- 12–30 vials — Mid-size Essential cases
- 30–100 vials — High Capacity cases (clinic/bulk storage)
Not sure? Use the Vial Case Calculator — enter your vial count and it'll recommend the right size.
