Peptide Vial Fill Sizes: Choosing Between 5, 10, 30, and 60 mg
2026-04-20 · 5 min read
Larger fills always look cheaper per milligram. Whether they are cheaper per experiment depends on how fast you consume a reconstituted vial.
Cost per milligram versus cost per run
AP3-R at 10 mg is $23 and at 60 mg is $65 — roughly a third of the per-milligram cost. But a 60 mg vial that sits reconstituted for weeks may cost more in discarded material than it saved.
Match fill to consumption
Choose the fill your protocol finishes inside its stability window. Smaller fills are the safer default for low-throughput work.
Mixing fills
Discount tiers count total kits, so you can stock both a small and a large fill of the same compound and still reach a tier.
Ordering, minimums, and pricing
Every SKU is priced per vial and sold in sealed ten-vial kits with a one-kit minimum. Volume tiers: 1 kit at list, 2 kits at 5% off, 3 kits at 7% off, 5 kits at 12% off, and 10 kits at 20% off. Domestic orders received by 2PM PT dispatch the same business day, and freight is free above $2,500.
All compounds are sold as chemical reagents for laboratory research use only — not for human or veterinary use.
