They had it in stock and the purity spec came back at >99.9% on the COA, which is tighter than some other sources we've tested — the benzyl alcohol content is typically around 0.9% or so, and that's what you need to keep microbial growth down during longer experiments.
Most buyers in peptide work go with the 10ml vials for semaglutide reconstitution, though we've ordered a few 30ml ones for the team running multiple assays because of that it's basically easier than cracking a new vial each time, but the 10ml format is what we usually have on hand.
Storage is pretty standdard — cool, dry place away form direct light — and we've found it holds up for 20 days or so after opening if you're careful about contamination, though the shelf life unopened is well over a year.
We've had some issues with other suppilers where the liquid had visible particulates, but this batch came back clear as expected; it's pharmaceutical grade, not just reagent grade, and that difference matters when you're diluting sensitive peptides.
Lead time was quoted at 2-4 weeks but they actually shipped in 10 days, and the MOQ was reasonable for a UK-based suppiler — we ordered 20 vials to start, and they threw in the COA without asking.
One thing nobody mentions is that if you over-dilute with too much bacteriostatic water, the peptide can degrade faster, so we're sticking with teh standard 2ml per vial protocol for semaglutide — anyway, this isn't meant for anything beyond research, so keep that in mind.
We can do as little as 10 vials for a custom order, but for the 30ml size, MOQ starts at 50 vials unless you're okay with a mixed batch.
Yes, every batch comes with a CoA that shows the purity is over 99.9%, tested by HPLC. Just ask for it with your order.
Custom packaging usually adds 7-10 business days to our standard 3-5 day lead time. We'll confirm the exact timeline once we know the specifics.
Absolutely—CAS 7732-18-5 is just water, and our >99.9% purity meets pharmaceutical grade standards. It's clear liquid, sterile-filtered, and intended for research use only.
Store it in a cool, dry place away from direct sunlight. At room temperature, it stays good for 12 months; refrigeration can extend that a bit, but avoid freezing.
