A reusable injector pen, five refillable cartridges, twenty 31G 4mm needles, draw-up tips, prep pads and a 30mL vial of bacteriostatic water. Everything for repeatable research dosing in one box. $85.
A complete pen dosing setup for research protocols that need consistent, repeatable volumes.

The Allstar holds a sealed 3mL cartridge, dials in 0.1mL increments, and fires the same volume every time you press the button. No counting units on a plunger at 6am.
The 31G 4mm needle is finer than a standard insulin needle, which matters when the protocol is daily. Between uses the cartridge stays sealed inside the pen, which is cleaner than an open vial and a loose needle.
The fill step is the one place a protocol usually gets messy. The draw-up tip threads through the cartridge cap, so the solution goes in cleanly with no exposed needle and no spill onto the pen mechanism. Once the cartridge is sealed inside the pen, the only thing that touches the liquid is the fresh pen needle you attach for each dose.
Wipe the pen exterior with a damp cloth if needed. Keep it dry and at room temperature. Replace the pen needle after every use and never store the pen with a needle attached. Check the cartridge for air bubbles before dialling and prime per your protocol.

The Allstar accepts standard 3mL insulin cartridges, the same format pharmacies stock. The 31G 4mm pen needles are the universal screw-on type. When the included consumables run out, replacements are a message away, and we keep both in stock for kit owners.
