We're confident in how it runs in the lab—nobody wants variability when you're dialing in a dose curve, and teh 99.9% purity by HPLC pretty much guarantees batch-to-batch consistency across your runs, which is pretty much what we
'v seen matter most for metabolic or GLP-1 pathway studies.
Short-term storage is straightforward, 0-4°C in a dark place is fine for a few weeks, but for long-term you'll want -20°C (check your freezer's fluctuations though) and that's where shelf life typically exceeds 2 years or so, assuming you don't thaw and refreeze unnecessarily.
it come lyophilized as a white powder in your choice of 5mg, 10mg, 15mg, or 30mg per vial, and the CAS—2023788-19-2—should match your internal screening; actually, the molecular weight at 4813 g/mol holds up consistently on our MALDI-TOF scans.
10 vials pack per box, which is handy for serial experiments, and we usually carry stock of the 5mg and 10mg sizes, but lead time on 30mg vials may be about a week longer because of custom fills.
Strict qualiy control here doesn't mean we sugarcoat it—one thing this isn't ideal for is any in vivo work expecting leftover buffer or salt content to be minimal; we lyophilize clean, but your reconstitution method still needs to be hands-on to pull full activity.
Also, most buyers in your position go with the 10mg vial anyway, since it gives flexibility across multiple reconstitution volumes without overspending on single-use formats.
Our MOQ for custom Semaglutide peptide manufacturing is 100 vials per batch, but we can discuss smaller runs for first-time clients or specific research needs.
Standard lead time is 2-3 weeks after order confirmation, including custom labeling and packaging. Expedited options are available for an extra fee.
Yes, every batch comes with a detailed COA from our in-house lab, covering HPLC purity, mass spectrometry verification, and residual solvent tests. Third-party testing is available on request.
Absolutely, we can fill custom dosages like 2mg or 50mg per vial, as long as the total batch volume meets our minimum fill requirements. Just let us know the exact specs.
Each vial is sealed under vacuum and packed in insulated containers with ice packs for short-term cooling. For longer transit, we use dry ice and temperature loggers to keep it stable.
