The 99% purity threshold is actually where most of our serious buyers start paying attention, because at that level you're getting consistent HPLC results batch after batch without the variability you'd see at lower grades—we run every lot through HPLC ourselves and can share the COA if you need it.
4,813.5 g/mol molecular weight, CAS 2023788-19-2, and it's soluble in water so reconstitution is straightforward, though you'll want to keep it at -20°C and protected form light once it's in solution; most people don't think to ask, but the shelf life holds up well for 24 months if stored properly in the orginal vials.
We usually have stock on the 5mg and 10mg vials, but the 20mg size can sometimes take 2-3 weeks or so depending on order volume, and MOQ is 10 —so basically one box minimum, though bulk pricing kicks in around 50 boxes or more if you're planning a larger study.
What it's not great for is anything requiring aqueous stability at room temperture for extended periods, since the peptide degrades pretty quickly if left out; that's just a fact of the molecule, not a flaw in our production.
Also, most buyers go with teh 10mg vials for routine work, but we've seen some labs prefer the 5mg for dose-response titrations where they need smaller aliquots—either way, the white to off-white powder appearance is consistent across all sizes.
The standard MOQ is 10 vials per box, which applies to all vial sizes (5mg, 10mg, or 20mg). If you need a smaller trial quantity, just reach out — we can sometimes accommodate that on a case-by-case basis.
Yes, we provide a COA with every batch that includes the HPLC purity result, typically showing ≥99%. Just request it with your order, and we'll include it in the shipment.
Keep it at -20°C and protect from light — this ensures the 24-month shelf life. Avoid freeze-thaw cycles, and reconstitute only right before use.
We can discuss custom vial sizes for bulk orders, but our standard packaging is set at those three dosages. For larger quantities, we might offer custom gram-level packaging — just let us know your needs.
For stock items, lead time is usually 3-5 business days after payment confirmation. If the batch needs to be produced fresh, it can take 7-14 days depending on the quantity.
