So you've been burned before by material that looked fine on paper but didn't replicate in your assays—everyone in this space has that one horror story, and what it come down to is consistency across batches, not just a single clean COA. We handle that by running every batch through ≥99% HPLC purity testing before it leaves, and you get the full certifcate of analysis with the shipment, no asking for it after the fact.
4813.5 g/mol is the molecular weight, CAS 2023788-19-2, and the purity threshold is tight—better than reagent grade for this kind of metabolic disorder research where even a few percentage points off can throw your. You'll see white to off-white powder in the vial, which is pretty much what you expect for a GIP/GLP-1 dual receptor agonist at this spec.

What catches some buyers off guard is teh retest policy—we usually have stock, but confirm lead time if you're ordering more than 50 units or so, because we do tempearture-controlled logistics from US and EU hubs and that can add a few days. Custom packaing is available for repeat orders, 5mg or 10mg depending on your batch needs, up to 30mg vials.

Also, this isn't suited for anything beyond research purposes—no in vivo work without your own ethics approval, obviously, but the real limitation is that the short-term storage window at 2-8°C is tight, about 20 days or so, before you really want it at -20°C for long-term. Shelf life exceeds two years when sealed and kept cold, which is actually better than some competing peptides we've handled.

One thing buyers don't always ask but should: we include the HPLC chromatogram with every COA, not just the purity number, so you can see the peak profile yourself. It's a small detail but it saves time when your internal QA wants to verify before you aliquot.
Anyway, bulk pricing works best when procurement teams need repeat orders—wire or credit card, and our company can adjust vial sizes if you're running a consistent protocol. 5mg vials are easier to handle for single-use reconstitution, but most buyers go with the 10mg for flexibility.
We can do as little as 10 vials for any size, including the 30mg. If you need a custom amount, just let us know.
Yes, we include a certificate of analysis with HPLC data confirming ≥99% purity for every order. Just request it when you place your order.
Absolutely, we customize packaging to your specs. Tell us the vial size you need, and we'll set it up.
For short-term use, keep it refrigerated at 2-8°C. For anything longer than a month, store it at -20°C to maintain full potency over its 2+ year shelf life.
We usually ship within 5-7 business days after payment confirmation. Custom packaging might add a couple of days, but we'll keep you updated.
