10 mL or 30 mL?
- Price: 30 mL vials were cheaper per mL as single vials. Packs of 10 mL vials narrow the gap.
- The 28-day window: once opened, a vial is commonly discarded within 28 days. A smaller vial wastes less if the lab uses only a little (see storage).
- Lot reports: the most complete report we found was on a 10 mL product.
PSPeptides: 10 mL only, in five pack sizes
