If you're signing up for retatrutide trials, you'll want syringes that don't add complexity — the Light100V4 and Light225V4 safety systems are basically designed around that. We've got them in 1ml or 2.25ml capacities, depending on your dosing needs, and they're both single-use glass prefilled syringes with a fixed injection dose.
passive safety mechanism engages one-handed, so you don't have to fiddle with caps or sleeves — it's pretty much automatic after use. This is especially useful when you're handling multiple injections in a day, say for a retatrutide study where protocol matters more than speed.
We usually stock these, but confirm lead time for custom labeling or color options — it's typically 20 days or so. They're not suited for high-viscosity compounds, though the 1ml version handles most peptide solutions fine.
What we've noticed is these syringes hold up better to vibration on automated lines than some competitors we've tried, and that's a real detail if your lab runs high-volume assembly. Teh IP is self-owned, so it's not a rebranded generic — tighter tolerance than most off-the-shelf units.
Also, the press cap closure is easy to remove without twisting, which matters when you're handling retatrutide trials or other sensitive research. Customiaztion is accepted, but we don't offer on-batch COAs unless you ask — that's a separate process.
