If you're working with fixed-dose retatrutide formulations in research, these syringes are basically what you want—the Light100V4 handles 1ml and teh Light225V4 covers 2.25ml, both with a passive safety system that activates one-handed.

We've been moving these for years, mostly to labs that need consistent dosing without the variability of manual plunger control, and the press cap closure keeps the seal tight during storage or transport (usually 2-4 weeks depending on your setup).

2.25ml is better for longer injection times, but the 1ml version is easier to handle with smaller batches—we see a lot of buyers go with the Light100V4 for routine work.
You can customize the color, overcap, or plunger rod, which matters more than you'd think when you're labeling multiple studies or training new staff.

We own patent on these, so what it does is eliminate the hassle of sourcing form a middleman, and every batch ships with a COA—roughly 5-7 days lead time for standerd orders.
The Light100V4 holds 1ml, while the Light225V4 holds 2.25ml. Choose based on your required dose volume for Retatrutide research.
Yes, they have unlimited viscosity compatibility, so they work with any Retatrutide formulation you're using.
