How to Calculate Vial Duration
Three inputs give you a complete research supply plan.
1
Vial size in mgConvert to mcg: multiply mg × 1000. A 5mg vial = 5,000 mcg total.
2
Dose per injectionThe mcg drawn each time. Fixed regardless of how much BAC water was added.
3
Injection frequencyHow many injections per day. Multiply dose × frequency to get daily consumption.
4
Duration calculationDays = Total mcg ÷ Daily mcg. Add a start date for exact reorder and end dates.
Total mcg = Vial size (mg) × 1000
Daily dose (mcg) = Dose per injection × Injections per day
Duration (days) = Total mcg ÷ Daily dose (mcg)
Reorder date = End date − 7 days
Example Scenario
Setup: 10mg vial, 500 mcg per injection, once daily Total: 10mg × 1000 = 10,000 mcg Daily use: 500 mcg × 1 = 500 mcg/day Duration: 10,000 ÷ 500 = 20 days If started Jan 1: Ends Jan 21 · Reorder by Jan 14
Common Questions
Frequently asked questions about peptide vial duration and supply planning.
How long does a 5mg peptide vial last?
A 5mg vial = 5,000 mcg. At 250 mcg/day → 20 days. At 500 mcg/day → 10 days. At 250 mcg twice daily (500 mcg/day total) → 10 days. Use the calculator above for your exact protocol.
How long does a 10mg peptide vial last?
A 10mg vial = 10,000 mcg. At 250 mcg once daily → 40 days (5.7 weeks). At 500 mcg once daily → 20 days. At 1mg once daily → 10 days. At 250 mcg twice daily → 20 days.
When should I reorder peptides?
Plan to reorder when you have 5–7 days of supply remaining to allow for shipping time. This calculator shows your recommended reorder date automatically — 7 days before your vial runs out.
Does BAC water volume affect how long a vial lasts?
No. The amount of BAC water only changes the solution concentration and draw volume per injection — it does not change the total peptide available. Duration depends entirely on total peptide content and dose per injection.
How many injections are in a peptide vial?
Injections = Total mcg ÷ Dose per injection. A 5mg vial gives 20 injections at 250 mcg, 10 injections at 500 mcg, or 50 injections at 100 mcg.
Should I account for waste?
This calculator gives the theoretical maximum. In practice, a small amount remains in the vial due to needle dead space — typically 2–5%. For a 40-injection vial, expect 38–39 usable injections in practice.
