First-of-its-Kind
The world's first peptide vial and self-injection device combined into a single precision instrument.
5mL Dosing
The world's first 5mL peptide cartridge — designed to match your protocol and prescription requirements.
c-GMP Certified
Manufactured in a c-GMP-certified facility to pharmaceutical-grade standards.
Designed in the USA
Engineered and designed in the United States with precision medical-grade materials throughout.
Medical-Grade Materials
Every component is made from precision medical-grade materials — safe, sterile, and built for clinical-level reliability.
Precision Dosing
Engineered for accurate, repeatable dosing with minimal waste — critical for high-value peptide compounds.
Feel the click. Trust the dose.
The mechanical click-dial delivers your prescribed dose in 0.5 IU detents — each step a tactile, audible click. No guessing with syringe graduations, no squinting at meniscus lines. Dial it, feel it, confirm it in the dose window.
Try it — drag the dial, scroll on it, or use the buttons.
Cartridge to injection in five steps.
Open the pen body, insert the 5mL cartridge until it clicks, close.
Screw a fresh needle onto the tip until snug. Never reuse needles.
Point up, dial out air until a drop appears at the tip.
Turn the click-dial to your prescribed dose. The window confirms it.
Press to skin, click the button, hold three seconds, dispose of the needle.

Everything you need to know.
The world's first combined peptide vial and self-injection device. A sealed 5mL cartridge loads into a precision pen body with a mechanical click-dial — no syringes, no manual reconstitution at dose time.
The click-dial adjusts from 0.5 to 50 IU in 0.5 IU detents, so the same instrument covers microdose protocols and full therapeutic doses.
Yes — manufactured in a c-GMP-certified facility (ISO 13485), EO sterilized to ISO 11135, from medical-grade materials throughout.
The device itself doesn't, but loaded cartridges follow your peptide's storage requirements — typically 36–46°F. It fits the Capsule, Mini, Max, Pro, and Fridge.
Yes. The pen with a loaded cartridge can be returned to cold storage (36–46°F) between doses — it fits the Capsule, Mini, Max, Pro, and Fridge. Cold doesn't affect the pen's mechanics, so you can inject straight from storage.
Yes — bulk ordering with custom labeling and co-branding is available for pharmacy partners. Request a sample kit from the pharmacies page.
