Basically, if you're handling GLP-1 compounds for weight management—whether it's retatrutide or something like semaglutide—this 3ml pen is what most of the regular buyers end up sticking with, and it's not hard to see why once you've handled a few dozen of them.

adjustable dose goes from 0.01ml up to 0.6ml, which covers pretty much every titration schedule I've seen for these peptides, and the injection itself takes about 6 seconds or less so you're not standing there holding it forever.

We usually have stock on the grey and blue models, though lead time for custom labeling (your logo, your dosing chart) runs about 20 days or so form order confirmation, so factor that in if you're planning a launch.


One thing people don't always think to ask is that the press cap closure is actually better than screw-top for these single-use pens—it keeps the cartridge seated firmly during transport, and I've had fewer complaints about leakage with this design than with the threaded ones.

Now, it's mechanicla, not electronic, so there's no battery to die mid-dose—but that also means no data logging, so if you're running a clinical protocol that needs injection timestamps, you'll need a separate logbook or app.

For bulk orders, we're typically at 1,000 units minimum, pricing around $2.80 per unit with the cartridge included, and we'll send teh HPLC and COA from the batch along with the shipment—most buyers just want to verify the fill volume consistency, and that's what we test for.
The pen has an adjustable dose, but you'll want to check the specific dose markings — it's designed for 3ml cartridges, so the dose range depends on the concentration of your Retatrutide solution.
Yes, we can provide a Certificate of Analysis for the pen materials upon request, and we recommend asking about COAs for the Retatrutide itself from your supplier.
For custom printed labels, the MOQ is typically 1,000 units, but we can discuss lower quantities depending on your order specifics.
Lead time is usually 15–20 business days after order confirmation, plus shipping time, which varies by method — air freight is faster but costs more.
It's designed for standard 3ml cartridges, but we recommend testing with your specific cartridge type first to ensure a snug fit and proper function.
