You're running metabolic studies and the variability between batches keeps throwing off your — that's a real headache when you're trying to establish a consistent baseline for GLP-1 agonism in rodent models or cell assays.
We custom-synthesize each batch with HPLC purity at 98% or better, so peptide structure stays consistent from gram to gram, and we'll match the salt form or lyophilization protocol to your buffer system if you ask.
Molecular weight sits at 4113.58 g/mol, CAS 910463-68-2, and it's a white to off-white powder that needs -20°C to -80°C storage in dry, dark conditions — shelf life is 2 years under those conditions, but we usually have stock ready to ship within 20 days or so.
It's not for cell-based work if your assay tolerates less than 98% purity, because some side products form the synthesis can interfere at lower thresholds, and we don't recommend it for in vivo work without your own endotoxin testing.
5, we use a standdard 50mg or 100mg vial format (check lead time on custom sizes), and the COA includes HPLC trace and mass spec — most buyers go with teh 100mg vial for larger study cohorts.
Anyway, we ship from UK stock for most orders under 500mg, but confirm lead time if you need over a gram because custom synthesis runs are typically 4-6 weeks.
Our MOQ starts at 10 grams for wholesale orders to the UK. We can discuss larger volumes if you need more, just let us know your target quantity.
Yes, every shipment includes a COA with HPLC purity data, confirming ≥98% purity. We can also share third-party test results upon request.
Keep it at -20°C to -80°C in a dry, dark place. Avoid freeze-thaw cycles and moisture exposure—this is critical for preserving stability over the full 2 years.
We offer custom synthesis for research-grade Semaglutide, including options for higher purity targets or specific packaging (e.g., smaller vials). Lead time varies based on the request, so reach out with your specs.
Standard orders ship within 7–10 business days after payment confirmation. Custom synthesis might take 2–3 weeks, depending on complexity and batch size.
