We've been getting a lot of inquiries about teh HL007 for retatrutide specifically, and the adjustable dose range from 0.01ml to 0.6ml is what most research teams want.

It uses a standard 3ml cartridge with a 9.7mm inner diameter, and the mechanical drive gives you that visual and auditory feedback at the end of each injection—usually takes about 6 seconds or so for a full dose.

The pen body is plastic, grey and blue, 17cm long, and we cap it with a press-on closure. Needle diameter runs 31G or 32G depending on your preference, and our company can do custom printed labels if you need branding for your trial.
One thing you'll want to confirm is that our company have the China Class II medical device registration and CDE packging record, so if your compliance team needs those documents, we can send them with the COA.

It’s basically not designed for anything thicker than what you'd expect form a peptide solution—veterinary formulations or heavy suspensions might clog the 31G needle, so keep that in mind.

MOQ on these is usually 500 units for the factory wholesale price, and lead time is roughly 20 days after we finalize the label artwork and dose customiztion.
We can start with as few as 1,000 units for a custom printed label run. Small test batches are available with standard labeling if you need to sample first.
Lead time is typically 15-20 working days after artwork approval. That includes production and CDE-compliant packaging. Expedited options are available if you're in a rush.
Yes, we provide copies of the Class II medical device registration and CDE packaging record milestone documentation. Just request them with your purchase order.
It's a continuous dial adjustment, not per click. You turn the knob to set any dose between 0.01ml and 0.6ml, and you'll hear and feel a click at each 0.01ml increment for confirmation.
Yes, the cartridge inner diameter is exactly 9.7mm, which is a standard size. Replacement cartridges are available for purchase separately, and we can supply them pre-filled if needed.
