Products
What's the difference between the pen models?
They differ in body style, dose range and feel. The V2 line is our compact everyday reusable pen with a concealed-needle mechanism. The V2-MAX and V4 lines offer a different body and dial design, and the Luxor pens ship with a carrying case. The Gansulin is a dial-operated pen with an adjustable 1–60 unit range. Each product page lists the specifics for that model.
What cartridges do the pens take?
Our reusable pens use standard 3 mL (300-unit) glass cartridges. We sell replacement cartridges in 10-packs. Always confirm cartridge compatibility with your specific pen before use.
Are needles included?
No. Cartridges, needles and accessories are sold separately unless a product page says otherwise. For the reusable pens we recommend 30-gauge or larger needles.
Can I use these with oils or viscous material?
No. These pens are not designed for oils or other highly viscous materials.
Do you sell peptides?
No. We sell laboratory hardware only — pens, cartridges, storage and related accessories. We do not sell peptides, biologics, pharmaceuticals, dietary supplements or any controlled substances.
