How Many Vials Do You Need? Peptide Protocol Planning Guide

One of the most common questions from people starting a peptide protocol: how many vials do I actually need? Here's how to calculate it.

The Basic Formula

Total vials = (Daily dose in mg x Cycle days) divided by mg per vial

Example: BPC-157 at 500mcg/day for 12 weeks = 42mg total. At 5mg/vial = 8.4 vials. Round up to 10 and add 1–2 spares.

Common Protocol Examples

Peptide Typical Dose 12-Week Vials Recommended Case
BPC-157 500mcg/day 8–10 10-vial Essential
TB-500 2.5mg twice/week 4–6 6-vial Essential
Semaglutide 0.5–2.4mg/week 6–12 10 or 12-vial Essential
Ipamorelin/CJC 300mcg 3x/day 15–20 20-vial Essential
