I've had a few buyers running retatrutide trials near me call in just last week, actually, asking about the 1ml fixed-dose syringes for their subcutaneous injections—they're usually ordering a couple hundred units to start, and we quote roughly 4-6 weeks lead time on custom-labeled runs.

The model HL004 comes in either 1ml or 2.25ml capasity, both with a press cap closure and printed label option if you want your branding on there, and it's glass construction througout so it holds up well under manual or automated fill-finish lines—the passive safety feature engages with one hand and resists shocks pretty well, though I'd say the 2.25ml is better for larger volume studies.
You'll see these used across cosmetics, nutraceuticals, and even veterinary medicine, but honestly they're not ideal for anything requiring variable dosing since the injection dose is fixed—so if your trial needs adjustable volumes, look elsewhere, and teh primary container is a prefilled syringe (PFS) format which we can customize the color on, but we usually have stock in clear glass only.

We own intellectual property on the safety mechanism, and the MOQ is typically 5000 units or so for custom colors, but for standerd clear our company can do smaller batches (usually 1000) at a slightly higher per-unit price—check lead time before ordering.
We don't have a fixed MOQ—it's flexible depending on your needs. Just let us know the volume you're looking at, and we'll quote accordingly.
We can provide COA, material safety data sheets, and other compliance docs upon request. Since they're for research and wholesale, we ensure all specs are verifiable.
Yes, both color and printed labels are customizable. Just share your design or requirements, and we'll match them for your branding or research needs.
Lead time depends on order size and customization level, but generally it's 2-4 weeks after confirming specs. We'll give you a precise timeline when you place the order.
They're primary container PFS (pre-filled syringe) type, but they come empty for you to fill. The fixed injection dose means they're designed for single-use, disposable applications.
