We run every batch through HPLC before it leaves the facility, and the purity consistently hits 99% — that’s tighter tolerance than some other suppilers we’ve seen in the market, though you should always verify with your own methods for critical work.
It’s a in 10mg vials, ten to a box, and we store everything at -20°C form the moment it’s packed, so you’ll want to keep it there until reconstitution or you risk losing activity faster than expected.
The molecular weight is roughly 4813.5 g/mol, and the CAS is 2023788-19-2, but what actually matters for your reconstitution is that it’s pharmaceutical grade peptide powder with a modified lysine side chain that improves solubility in water or bacteriostatic water.
Most buyers go with teh 20mg vial for longer studies or higher dosing protocols, though the 10mg size is easier to handle if you’re working with smaller volumes or multiple compounds at once, and we usually have stock but confirm lead time (usually 2-4 weeks on larger orders).
We include a COA with every shipment, and our retest policy covers any batch that doesn’t match spec within 30 days of receipt — just keep the unopened vials at -20°C and we’ll handle the replacement.
This isn’t suited for anything beyond research use, and the PEGylation actually extends half-life in vivo but means nothing in cell-free assays, so plan your dosing intervals accordingly if you’re running animal work.
We require a minimum of 1 box (10 vials) per order. Each box contains 10mg/vial, so you get 100mg total.
Yes, every batch ships with a COA from our lab showing the 99% purity and HPLC test results. Just request it with your order.
The -20°C freezer storage keeps the peptide stable and prevents degradation. If left at room temp for more than a few days, it can lose potency.
We typically stick with 10 vials per box for inventory reasons, but we can discuss bulk orders if you need larger quantities. Custom labeling is also available on request.
Standard lead time is 3-5 business days for processing, then shipping takes another 5-10 days depending on your location. Rush orders can be arranged for an extra fee.
