You're looking at roughly 1.5mg per pen for most of these batches, but our company can adjust concentration depending on your protocol — just tell us what you need and we'll set the fill level accordingly.
We've been running these formulations at >99% purity by HPLC for the last six months or so, and the white powder reconstitutes cleanly every time, though you'll want to store it at -20°C for long-term stability or it'll degrade faster than you'd expect.
It's better than reagent grade for this kind of work because teh tolerances are tighter on the peptide chain itself, but honestly, it's not suited for anything beyond research — no clinical use, no animal dosing, just lab bench stuff.
Most buyers go with the 10-unit boxes for convenience, but we can do custom packaging if you're running a larger study and need 50 pens or more per shipment — just give us a heads-up on lead time.
Also, we usually have stock on the 0.5mg and 1.5mg configurations, but the higher concentrations (3mg or so) might require a production run, so confirm lead time before ordering if you're in a hurry.
One thing you wouldn't think to ask: the pen itself has a glass cartridge that's pretty standerd, but needle hub is a proprietary fit, so you'll need to order extra needles from us or check compatibilty first.
We can work with you on MOQ depending on your needs, but typically we start at around 100 units per order. For smaller trial batches, just reach out and we'll see what we can do.
Standard lead time is about 10 to 15 business days after order confirmation, but if you need it faster, we can expedite for a small fee. Custom packaging may add a few days.
Yes, we supply a COA with every batch showing the actual purity and test results. Just request it when you place the order and we'll include it with the shipment.
Absolutely, we offer customizable packaging including your own branding and label design. Just send us the specs or artwork and we'll handle the rest.
For maximum stability, keep them at -20°C in a freezer. If you're using them within a few weeks, refrigeration at 2-8°C is fine, but avoid repeated temperature changes.
