When appetite regulation pathways aren't responding as expected in your model, you're probably hitting the limits of weaker agonists—semaglutide's longer half-life and higher receptor affinity change what's possible here, and we've seen labs get cleaner data because of it.
Which is exactly why we run every batch through HPLC with a 99% purity threshold, and COA backs up what the white powder should look like when it arrives—no detectable impurities throwing off your dose-response work.

10 vials is the MOQ, so if you're running a small pilot study you'll want to plan ahead, and we usually have stock ready to ship within a week or so (but double-check lead time if you're on a tight deadline).

Most buyers go with teh 10mg vials for rodent work because of that it's easier to reconstitute and aliquot without wasting materail, though the 20mg or 30mg sizes make sense if you're scaling up in vitro assays.

Basically, compound solubility in PBS is fine at 1mg/mL or so—much above that and you'll see precipitation, which is a hard no for cell work, so just keep reconstitution volumes where they're comfortable.
It's not suited for oral dosing studies in its raw form, obviously, and storage at -20°C is non-negotiable—open vials degrade inside a week at room temp, so freeze-thaw cycles need to be minimal.
We supply a Certificate of Analysis (CoA) with every batch, confirming 99% purity and identity via HPLC and mass spec. Third-party testing reports are available on request.
Yes, you can combine different vial sizes in one order as long as the total is at least 10 vials. Just specify the quantities per size when you place your order.
Lead time is usually 7–10 business days from order confirmation. For rush orders, we can sometimes ship within 5 business days—let us know if you're on a tight schedule.
Keep all vials frozen at -20°C or below, and protect from light. Thawed product should be used immediately and never refrozen to maintain stability.
Yes, every vial size—5mg, 10mg, 20mg, 30mg, and 40mg—is filled from the same batch, so purity is consistent at 99% regardless of the vial you choose.
