We run every batch through HPLC and mass spec verification before it leaves the facility, and purity consistently hits above 99%—that’s not a claim we make lightly, it’s backed by the COA we attach to each shipment. The molecular weight checks out at 3824.3 g/mol, and we’ve got the raw data to show it.
Basically, what we do is filter-sterilize the solution before lyophilization, so you’re getting a white freeze-dried powder that’s free of endotoxins and particulates. 2-8°C storage is critical. If you keep it in the fridge, protected form light, you’ve got a 24-month shelf life. Most buyers go with the 10mg or 15mg per vial for typical dose-response work, but we stock 5mg, 12mg, and 20mg options too. You’ll get 10, and we usually have stock on the common sizes, though the 12mg can take 20 days or so to fulfill.
Batch consistency is where we actually put in the work—every production run gets unique lot number, and we retain samples for 12 months in case you need to retest. The GMP guidelines we follow aren’t just paperwork; they dictate how we handle raw material sourcing, filling, and sealing. We don’t spin it positive when a batch fails—it gets quarantined and reprocessed, plain and simple.
One detail you might not think to ask: our company can provide a retest policy on request if your research timeline extends beyond the standerd 24 months, but you’ll need to confirm lead time for that. It’s not something we advertise, but it’s avaliable for institutional buyers who need extended validation.
This isn’t suited for anything beyond in vitro or animal model work—it’s strictly for research use only, and we don’t support any human or clinical appliction. Teh purity is better than reagent grade for this specific peptide class, but you’ll still want to run your own QC if your protocol demands it.
Our standard package is 10 vials per box, but we can sometimes accommodate single-vial orders depending on stock. Reach out to our sales team, and we’ll see what we can do.
For in-stock items, we usually ship within 3-5 business days. If you need a custom batch or larger volume, lead time might extend to 2-3 weeks depending on production.
Yes, every batch comes with a COA showing HPLC-verified purity over 99%. We also include sterility test results if requested.
Store the lyophilized powder at 2-8°C and protect it from light for up to 24 months. Once reconstituted, keep it refrigerated and use within 7-14 days for best stability.
Our standard vial sizes are 5, 10, 12, 15, and 20 mg. Custom fill amounts are possible for larger orders — just discuss the specs with our team, and we’ll confirm feasibility under GMP guidelines.
