Peptide Injection Pens

Prefilled peptide pens for laboratory research use. Each pen arrives pre-dosed and ready to administer — no reconstitution, no measuring, no syringes. Dial the dose, administer, and keep the pen refrigerated between uses.

Available injection pens

Pen or lyophilized vial?

• Convenience — pens come pre-mixed and pre-dosed; vials must be reconstituted with bacteriostatic water first.
• Dosing control — pens dial in fixed increments; vials let you set your own concentration and draw any volume.
• Storage — a sealed lyophilized vial is stable at room temperature; an opened pen must stay refrigerated.
• Cost — vials are generally lower cost per milligram.
