We've been shipping this compound for a while now, and the biggest concern buyers have is always about batch-to-batch consistency — you get a 99% purity reading on the COA, but that's just the start. Each lot is tested by HPLC, and we keep the raw data on file for at least two years, so if you ever need to retest, we can pull the original chromatograms. molecular weight is 4813.527 g/mol, which matters for accurate reconstitution — you'll want to use that when calculating molarity for your.
Storage is pretty straightforward: keep it at -20°C, and it'll hold for about two years or so form manufacture date. But here's the thing — once you reconstitute, the stability window drops to roughly 48 hours at 4°C, so plan your experiments accordingly. We usually have stock of the 10mg vials, but the 15mg vials can take 20 days or so for production if we're out. Also, the lyophilized powder is white, and if you see any discoloration, that's a red flag — we've never had that issue, but it's something to watch for.
Most buyers go with the 10mg vials for general metabolic studies, but the 15mg ones are better if you're running chronic dosing protocols — fewer vial switches, less waste. (Usually it's 10, but we can split that if your MOQ is lower.) The CAS number is 2023788-19-2, which you'll need for your lab's inventory system, but honestly, the purity is what you're paying for — 99% is tight, and we back it with a certificate of analysis for every lot.
We don't recommend this for anything involving live human or animal trials — it's strictly research use only, and the GMP and ISO certifications are there to show the manufacturing process is clean, not that it's ready for clinical use. What it does is give you reliable dual GLP-1/GIP agonist for your comparative studies with semaglutide pen formulations. One detail that catches new buyers off guard: the retest policy is 18 months from manufactyre date, and we can issue a fresh COA if you send a sample back — no charge, just cover shiping.
Anyway, if you're running a larger project and need multiple lots for side-by-side work, let us know — we can reserve batches from the same production run to minimize variability. The packging is straightforward: white vials with rubber stoppers, sealed under vacuum, and shipped with ice packs in insulated containers. We've handled orders from 50 vials up to 10,000 vials, and the lead time is usually consistent regardless of size — about 2-4 weeks for the standard 99% purity.
