What really sets these apart is the passive safety system that clicks into place with one hand — no fumbling, no extra steps, and it's a genuine upgrade over the standard slip-tip syringes most labs use for retatrutide trials.
They're built for 1ml or 2.25ml prefilled glass syringes, ISO standard, with a press cap closure that holds tight but isn't a pain to remove. The injection dose is fixed, so you're not guessing volumes, and teh customization options go beyond just color — printed labels are avaliable if you need batch tracking or branding on barrel.
We typically stock these in moderate quantities, but MOQ can vary depending on whether you need custom labeling or a specific color run — usually 50,000 units or so, but confirm lead time if you're under that. The patent is self-owned, which means we control the design, and that keeps the tolerances tighter than most generic safety syringes on the market.
One thing most buyers don't think to ask: these are designed for automated assembly lines, so if you're hand-filling, you'll want to check compatiblity with your fill equipement first — it's not a dealbreaker, but it's worth confirming. Also, they're not ideal for anything requiring a variable dose per injection, since the fixed dose is set at manufacturing.
Basically, if you're running retatrutide trials and need a safety syringe that works with standdard PFS formats, this is a solid pick. The passive safety feature alone cuts down on needlestick risk pretty much entirely — and that's hard to argue with in a research setting.
