Actually, it's a white freeze-dried powder we handle regularly in sealed vials with aluminum caps, and the purity is confirmed at 99% or better by HPLC and mass spec — we've got the COAs to show for it if you need them, but you'll have to store it at -20°C protected form light once it arrives.
Most buyers go with the 10mg or 50mg vials for their research, and the solubility is straightforward in water, so reconstitution isn't a headache, though we'd warn you it's not suited for anything beyond lab use — that's the legal line we stay behind.
What it does is weigh in at roughly 4109.6 Da with that long sequence of amino acids, and the solid-phase synthesis gives tighter tolerance than some cheaper alternatives, but we don't have a CAS number for it, so check your own documentation requrement before ordering.
We usually have stock on the 2mg, 5mg, and 10mg sizes, but the 50mg and 100mg might need a lead time of 20 days or so — just confirm with us first, as MOQs can apply for the larger formats.
Also, the shelf life is 24 months when stored properly, but once you reconstitute it, you're looking at a much shorter window, and that's a detail some buyers forget until they've got a vial sitting on the bench too long.
It ships with GMP and ISO 9001 certs on request, though we don't always include them in every package unless you ask, and the packaging is pretty standard — just teh vials in a box with ice packs for transit.
We don't have a strict MOQ on the smaller sizes like 2mg or 5mg — you can order single vials for testing. For larger sizes like 50mg or 100mg, we typically ask for a minimum of 10 vials per order, but that's flexible depending on your project.
Lead time is typically 3-5 business days for stock sizes like 100mg, and we ship from our warehouse within 24 hours of payment confirmation. Express shipping takes about 5-8 days to most destinations.
Yes, every batch comes with a CoA that includes HPLC purity data, mass spec results, and amino acid analysis. We can also share the GMP and ISO 9001 certificates on request.
We can do custom labeling for bulk orders — just let us know your requirements. Standard packaging is sealed vials with aluminum caps, but we can adjust vial size or add your logo for orders over 100 vials.
Keep it at -20°C, protected from light, and avoid freeze-thaw cycles. If stored properly, it stays stable for 24 months. Once reconstituted in water, use it within a few days and keep it refrigerated.
