Needle-Free Multi-Dose Pen Injector for Weight Management & Aesthetic Programs
R&G Bio manufactures needle-free injection systems for weight management clinics, med spas and aesthetic brands — a complete 3-component platform ready for your private label slimming and body-contouring programs.
A spring-powered multi-dose pen delivers weight management peptides and beauty serums through a micro-orifice as a fine high-pressure stream — no needle, no sharps waste, no client anxiety, with consistent dosing session after session.
Every unit is EO gas sterilized, batch-coded for full traceability, and produced in Class 100,000 cleanrooms under an ISO 13485 quality system. Review our certifications and compliance documents and see how we manufacture before you place a bulk order.
We also run full OEM/ODM programs: custom specifications, private labeling, and packaging built around your brand, with factory-direct MOQs and tiered wholesale pricing.

Why Switch to Needle-Free Injection Technology?
😰 Client Drop-Off & Program Abandonment
Needle anxiety is the #1 reason weight management clients quit injectable programs early — every abandoned program is lost recurring revenue for your clinic.
⚠️ Sharps Handling & Licensing Hassles
No needles means no sharps disposal costs, fewer regulatory hurdles, and a simpler workflow for your staff — ideal for high-volume aesthetic and slimming practices.
🩹 Skin Trauma & Uneven Absorption
Repeated needle injections cause hard lumps and localized tissue damage, reducing absorption consistency — a visible comfort issue your long-term program clients will notice.
The R&G BIO Needle-Free Solution
Our disposable sterile needle-free injector uses high-pressure jet technology (micro-aperture nozzle) to deliver formulations as a fine mist directly into subcutaneous tissue—no needle required. Perfect for weight management peptide programs, fat-dissolving mesotherapy, hyaluronic acid treatments, and insulin delivery.
Technical Advantages
Mist-Like Dispersion
Atomized medication spreads diffusely over 15-20mm area for faster, more complete absorption vs. pooled liquid from traditional needles.
Digital Dose Control
Precision adjustment window (0-35 units) ensures accurate delivery every time. Multi-dose capability reduces medical waste.
Zero Cross-Contamination
Single-use sterile ampoules with EO gas sterilization help reduce infection risks and needle-stick hazards.
Universal Compatibility
Type A adapter for plastic screw caps, Type B for metal seals. Compatible with all standard insulin and HA vials.
Needle-Free vs. Traditional Needle Injections
Needle-free injection outperforms traditional injection in pain control, psychological comfort, safety (needlestick/infection risk), and drug absorption efficiency—especially suitable for clients on long-term weight management or aesthetic programs who return for regular sessions, and for anyone with needle sensitivity.
