It’s not a standalone injection device for retatrutide itself—what it does is accept a 3ml cartridge, so you’re still sourcing the peptide seprately and loading it into the chamber, but for anyone running with GLP-1 analogs or retatrutide, the precision here beats manual syringe work by wide margin.
The 0.01ml increment (which is 1IU on the typical scale) gives you a fine enough step for most rodent or small-animal studies, and the injection time is capped at 6 seconds, so you’re not dealing with variable dwell that can skew absorption data.

We’ve seen these hold up better than reagent-grade pens for repeated use—the medical-grade plastic doesn’t crack after 50 cycles or so, and the needle compatiblity with 31G or 32G means you can use standard fine-gauge tips without adapter headaches. The dimensoins (172mm long) feel a bit long in the hand, but that’s pretty much the trade-off for the φ9.7mm cartridge diameter. Also, the auditory feedback is actually consistent—you’ll hear a click at full depression, which isn’t always true on cheaper units.
Most buyers go with the 0.01ml-0.6ml range for retatrutide or semaglutide research, but if you’re working with higher-volume doses (say, 0.8ml per injection), this won’t work—you’d need a different cartridge system. We usually stock about 200 units, but confirm lead time if you’re ordering more than 50.
Customization is available for bulk orders (typically 100+ units), and our company can adjust the injection time slightly if your protocol demands it, though the ≤6 seconds is already tighter than most off-the-shelf pens. Class II certification matters for compliance if you’re in a regulated lab, but for pure research use, it’s more about the consistent 0.01ml increment than the paperwork. Anyway, you’ll get a COA with each batch—HPLC-verified for the device’s mechanicla tolerance, not the peptide, since that’s on your end.
We can start from 500 units for a custom order, but if you just need plain units without branding, we can do smaller quantities. Just let us know your volume.
Typically 15–20 working days after deposit and artwork approval. For urgent orders, we can sometimes squeeze it to 12 days.
We have the Class II Medical Device certificate on file and can share it upon request. It covers the device's design and manufacturing standards.
Yes, the dose range goes up to 0.6ml, so 0.5ml is well within spec. The 0.01ml step allows precise adjustments for retatrutide or GLP-1 dosing protocols.
Standard packaging is individual blister packs with a sterile barrier, 50 units per carton. For bulk orders, we can do custom inserts or boxes with your logo.
