Multi-Size Vial Storage Case – Fits 3mL, 5mL & 10mL Vials Most vial storage cases are built for one vial size — which works fine until your protocol involves a mix of 3mL, 5mL, and 10mL vials that don't all fit in the same organizer. This modular case solves that problem with a flexible adapter system that lets you configure any slot for smaller 3mL vials while larger slots handle 5mL and 10mL vials natively — all in one case, one organized layout, no juggling multiple storage solutions. Available in 6, 12, 20, 30, and 49-slot configurations with included adapters, this is the most versatile vial storage case in our lineup. Who This Case Is For This case is designed for anyone managing a protocol that involves more than one vial size, including: TRT or HRT patients who combine 10mL hormone vials with smaller 3mL peptide or compounded vials in a single routine Compounded GLP-1 users who source semaglutide or tirzepatide in different vial sizes and need one organized storage solution Peptide users running multiple compounds across different vial formats simultaneously NAD+ or wellness protocol users who combine large-format and small-format vials in the same routine Anyone who has outgrown single-size storage and needs a flexible system that adapts to their changing protocol How the Adapter System Works Each case is sized natively for 5mL and 10mL vials (up to 23–24mm diameter × 55mm tall). Included adapters insert into any slot to convert it for smaller 3mL vials (approximately 17mm diameter × 40mm tall), letting you mix vial sizes freely within the same case. Adapters can be placed in any slot — configure the layout to match your exact protocol.
