We're looking at roughly 2-3 weeks lead time on the 25kg drum orders right now, stock availability fluctuates but we usually have a batch in cold storage at 2-8°C. The powder comes as a white to off-white lyophilized cake, soluble in water, and it's shipped with gel packs in insulated containers — you'll want to confirm the shipping window if you're in a warmer climate.
It's a 4113.6 g/mol peptide, C187H291N45O59, and the HPLC shows 99% purity consistently across batches. What that means in practice is you're not dealing with truncated sequences or oxidation byproducts that can throw off your. The CAS is 147732-56-7, and we run a COA on every production lot — the pharmaceutical grade designation is based on tighter endotoxin limits than typical research grade.
Most buyers go with the 25kg drum for metabolic studies or GLP-1 analog screening, but honestly it's overkill if you're only running small-scale binding assays. For those applictions, a 1g or 5g vial would make more sense — our company can split the drum but the MOQ is 1kg if you want to test a sample first. Also, it's not suited for anything involving cell-based work with serum-containing media, the solubility buffer matters more than people think.
We store it at 2-8°C protected from light, and the powder is stable for 24 months or so under those conditions — once reconstituted, you've got about 7 days at 4°C before degradation becomes measurable. One thing most buyers don't ask about is the residual TFA content; ours is typically below 1% by weight, which matters for in vivo work but isn't always on the spec sheet.
Anyway, for the 25kg drum you're looking at roughly $3,500 per kg depending on volume, and we can do partial pallet shipments if you need staggered delivery. The packaing is a single HDPE drum with a tamper-evident seal, double-bagged inside. Lead time is usually 15-20 business days after payment, but we have some stock in our US warehose — give or take 50 units — so check before ordering if you're in a hurry.
Our MOQ is one 25KG drum. If you need a smaller quantity for initial testing, we can discuss a trial sample — just reach out.
Lead time is usually 15-20 working days after order confirmation and payment. For rush orders, we can sometimes expedite — let us know your timeline.
Yes, each batch comes with a COA showing 99% purity, HPLC analysis, and other specs like appearance and solubility. We can also send third-party test reports if needed.
Store at 2-8°C, protected from light. Once opened, keep the container sealed and dry to avoid moisture absorption — the powder is hygroscopic. Use within a reasonable timeframe.
We can split the 25KG drum into smaller sealed bags or vials at your request. Just let us know the preferred pack size and we'll adjust the quote accordingly.
