We’ve been running these batches for a while now, and the 99% purity holds steady across — it’s not something our company have to chase every time. The 10mg per box is the standard unit, and most buyers go with that for smaller-scale work, though you can request 5mg or 10mg depending on your batch if you’re ordering in volume. That shelf life of 2 years is pretty generous for a lyophilized peptide, and we’ve seen it hold up fine in cool, dry storage — no special fridge needed unless you’re pushing the timeline.
What it does is provide a consistent baseline for your assays, and we’ve had researchers tell us it’s better than reagent grade for this kind of work because of the tighter tolerance on the HPLC results. The COA we include with each shipment covers the purity and a few other specs, but we don’t always list the molecular weight on the label — you’ll have to request that separately if you need it. It’s not suited for anything beyond research use, so don’t plan on in vivo work without proper protocols.
The packging is straightforward: a PP foil bag inside a box, and we ship it in a padded envelope for single-box orders. For customized orders, the MOQ jumps to 10 boxes, and we usually have stock on those, but confirm lead time — sometimes it’s 20 days or so if we’re between production cycles. The foil bag is heat-sealed, and we’ve never had a leak issue in transit, though you’ll want to open it in a clean enviroment to avoid contamination.
We’re a factory in China — Haicai is the trademark — and we handle the supply and wholsale side directly, so there’s no middleman markup on the price. The sample is availble if you want to test a batch before committing to a larger order, and our company can customize the packaging if you’re ordering 10 to 50 boxes. One thing you might not think to ask: the foil bag is opaque, so you won’t see the powder through it, but the box has a label with the batch number and expiry date printed clearly.
Honestly, it’s a solid option for routine research, but if you’re looking for something with a different CAS or a specific salt form, this isn’t that — it’s the standard Selank peptide, and we don’t offer variants. The shelf life is 2 years from the manufactyre date, and we rotate stock regularly, so you’re not getting old material. Anyway, the spec sheet is accurate, and we’ve got the HPLC data if you ask.
Keep it in a cool, dry place away from light, ideally sealed in the PP foil bag. If stored properly, the 2-year shelf life holds up just fine.
Yes, samples are available. Just reach out and we can arrange one for you to test the quality first.
Regular orders require a minimum of 1 box, but if you need customized packaging, the MOQ jumps to 10-50 boxes depending on the specifics.
We can provide a certificate of analysis showing the 99% purity and other specs. Just ask when you place the order.
It comes in a PP foil bag inside a box by default. That keeps it stable during shipping and maintains the 2-year shelf life.
