We’ve done a ton of these for retatrutide trials and weight management research — HL007 is the standard grey/blue pen with a 3ml cartridge, adjustable dose from 0.01 to 0.6ml, and it’s all mechanical and press cap closure, so no batteries to worry about.
Most buyers go with the printed label option for tracking batch numbers or trial participant IDs, and it’s disposable so you’re not reusing on different subjects — pretty straightforward design, and the 17mm pen body fits standerd pockets or storage trays.
It’s not suited for high-viscosity compounds (like some oil-based veterinary formulas) because the narrow bore clogs faster — but for GLP-1, HCG, or nutraceutical supplements it works fine, and the 0.6ml max dose is better than many fixed-dose pens we’ve shipped.
We usually have stock for 50 units or so, but MOQ is 500 if you need a custom color or label design, and lead time is roughly 20 days (check if customization delays it further) — COA and HPLC data for plastic quality are included with bulk orders.
Also, the adjustable dose works via a simple click mechanism (0.01ml per click), which reduces dosing errors, though you’ll want to double-check teh injection speed for retatrutide trials — some researchers prefer a slower push to avoid leakage.
Packging comes in bulk trays of 100 pens per box, or our company can do individual blister packs if your protocol requires sterile handling — just note the cartridge compatibility with standard 3ml glass or polymer cartridges.
MOQ is typically 1,000 units for standard orders, but we can discuss smaller trial runs if you're just starting your retatrutide study. Custom labeling might bump that up slightly, so let us know your volume.
Yes, the pen is designed for 3ml cartridges, which is a common size for retatrutide research batches. Just make sure your cartridge fits the 17mm diameter spec—most standard ones do, but check your supplier's measurements.
Sure, we can provide a material compliance sheet and basic safety documentation upon request. For specific research-grade certs like USP Class VI, we'd need to confirm with our production team—just ask.
Standard lead time is around 15-20 working days after order confirmation. Custom printing might add a few days depending on design complexity, but we'll give you a firm timeline once we see the artwork.
They come in bulk packs of 100 per sealed bag, with an option for individual blister packs at a small extra cost. For research use, bulk is usually fine unless you need sterile singles.
