We've been sourcing this exact CAS 2023788-19-2 bulk white powder for about eight months now, and basically it's replaced our previous peptide supplier entirely — purity consistently hits above 99% on HPLC, which is tighter than reagent grade for metabolic work.
Storage at 2-8°C is non-negotiable, and we've had no stability issues across batches if you keep it there; the molecular weight of 4813 checks out on every COA we've received, and the white powder appearance is uniform.
37 vials arrived in our last order, and the lead time was roughly 20 days or so form PO placement. It's pharmaceutical grade, but we treat it under controlled lab conditions for research use — it's not suited for any in vivo applicaion obviously.
One thing we didn't think to ask upfront but mattered: teh powder compresses slightly during shipping, so weigh rather than scoop by volume. We usually have stock on hand, but confirm lead time for bulk over 50 grams.
Packaging was standard amber glass with desiccant, and we've run it alongside LY3298176 from two other sources — this batch had the cleanest HPLC trace across three separate runs.
We typically start at 10 grams for bulk orders, but we can discuss smaller quantities depending on your needs.
Yes, every shipment includes a COA showing the >99% purity, along with HPLC and mass spec data. Third-party testing is available on request.
Keep it at 2-8°C in a sealed container away from light and moisture. That fridge range keeps it stable for long-term use.
For standard quantities, we ship within 3-5 business days after payment. Larger orders might take 7-10 days depending on stock.
Sure, we can pack it in sealed bags or vials, with custom labels if needed. Just let us know your preferred size and format.
