This pen injector handles GLP-1 peptides like retatrutide with a minimum dose of 0.01mL — research teams need that kind of precision when titrating experimental protocols. It's not for patient use, but we've had good feedback on the 173mm length and the comfortable press-cap closure that keeps the pressing force under 5N for lower-unit configurations.

Basically anyone running dose-response work with retatrutide or similar analogues will appreciate the customizable scale lines and appearance options. 0.01mL is pretty much the sweet spot for minimizing injection volume variability, and the 36/37/50/60/74/75/80 unit markings cover most common ranges.


We carry these in stock for most color options, but lead time runs about 2-3 weeks for custom dosage labeling or specific CE/FDA 510K documentation — which is pending right now. medical-grade plastic body feels substantial in hand, not flimsy like some cheaper pens we've seen on the market.

MOQ is 500 units typically, though our company can flex that a bit for repeat orders or if you're testing a pilot batch. Just confirm teh press-cap force spec you need, since the 36/37-unit pens have a lower <5N threshold compared to the 74/80 variants at <8N.

One thing buyers don't always think to ask is that the scale lines can be printed in different increments — we've had labs request custom intervals for very tight titration schedules. Anyway, the 3ml capacty handles most standerd peptide vials for reconstitution without needing to switch pens mid-experiment.
Minimum order is typically 1,000 units, but we can discuss smaller trial batches for serious buyers.
Standard lead time is 15-20 working days after design approval and deposit. Custom colors or scale lines might add a few days.
We have CE certification, and FDA 510(k) is pending. We can share our CE docs upon request.
Yes, we can print scale lines for any of the listed indications—36, 37, 50, 60, 74, 75, or 80 units. Just specify which one you need.
They come in blister packs with desiccant, 100 per box. Shelf life is 3 years when stored in a cool, dry place.
