A lot of labs struggle with batch-to-batch variation in peptide studies—especially with protocols running eight weeks or more, last thing you want is a purity drop mid-series that forces a protocol restart or data toss.
What we've done is lock down every step; each batch goes through HPLC-run purity analysis, and we keep those raw chromatograms filed alongside a full COA that singles out your impurity profile down to ≤1.0% rather than just quoting a blend number.
You'll get a white powder with ≥99.0% purity confirmed—average molecular weight sits at 4813.45—and we test moisture content seperately if you need it, though it's usually ≤10% form our side anyway.
Each 1mg vial is packed under inert gas (nitrogen flush mostly), so moisture pickup during storage is minimal before you even hit -20°C, but you probably already know it's pretty much insoluble in water so DMSO at 3mg/mL is your standdard route.
Actually, if your protocol needs a retest window beyond the 24-month shelf life, we'll run a fresh HPLC on sample basis within maybe two weeks if you ship it back—just check our retest policy, it's not teh same as a rush replacement.
We recommend you stick to research-grade users here; it's not formulated for anything clinical, same as most raw 99% semaglutide powder in the UK market, and typical MOQ is 20 vials or so for a first order.
Yes, our Semaglutide meets ≥99.0% purity via HPLC, with single impurity capped at ≤1.0% and peptide content at ≥80.0%.
We offer flexible MOQs depending on your needs. Standard packaging is 1mg/vial, but we can customize the vial size or bulk packaging for larger orders.
Lead time is typically 5-10 business days after order confirmation. Yes, we supply a Certificate of Analysis (CoA) with each batch showing HPLC purity, moisture content, and other specs.
Store at -20°C in a dry environment. Avoid freeze-thaw cycles, and keep the vial sealed until use to prevent moisture absorption.
We manufacture to pharmaceutical grade with ≥99.0% purity as standard. Custom purity levels or tighter impurity specs can be discussed for bulk wholesale orders.
