We've seen a lot of people asking where to buy semaglutide UK for research, but the dual agonist profile is what really sets this apart for certain studies. It's a white powder, CAS 2023788-19-2, with a molecular weight of 4813.45 and purity typically at 98% or higher per the COA — that's better than reagent grade for this type of work. Most buyers go with the 10mg vial for smaller runs.


The molecular formula runs C225H348N48O68, and it basically mimics natural GIP at GIP receptors while also hitting GLP-1 pathways, which gives you that enhanced efficacy in glucose control and weight management research compared to selective GLP-1 agonists alone. Storage is critical: keep it dry and dark at 0–4°C for short-term (days to weeks) or -20°C for long-term (months to years). Shelf life is over 2 years when stored properly, but we usually have stock, so confirm lead time for larger orders.

98% purity is the minimum we guarantee, but actual HPLC results often come in a bit higher — still, don't expect it to be suitable to anything beyond in vitro or animal model work. It's not suited for human use, and we're clear on that. The HS tariff code is 2934.99.9001 if you need it for customs.

Custom packging is available for wholsale orders — our company can do 5mg or 10mg depending on your batch, and the MOQ is typically 10 vials or so. For OEM, we can label it as LY3298176 or whatever you need, but the lead time adds about 20 days or so. One thing you might not think to ask: the powder can be a bit hygroscopic, so open it in low-humidity environment.


Logistics are straightforward for UK orders — we ship via courier with tracking, and it usually takes 7-14 business days. For research use only, obviously. And if you're comparing it to semaglutide, teh dual agonist mechanism is actually what makes it more potent in some glucose control studies, but it's not a direct replacement.
Yes, we include a CoA with every shipment that shows the exact purity, residual solvents, and heavy metals for that specific batch. Our ≥98% purity is a minimum spec, so you can expect consistent quality across batches.
Our standard MOQ is 10 grams, but we can supply as little as 1 gram for research use. Just let us know your required amount and we'll quote accordingly.
Shipping to the UK usually takes 5-8 business days via express courier. We handle all export documentation and provide the HS code (2934.99.9001) to smooth customs clearance, but import duties are the buyer's responsibility.
Absolutely — we can package in vacuum-sealed foil bags or amber vials, and label with your specs. Just tell us the size and storage format, and we'll accommodate.
For long-term storage, keep the powder at -20°C in a dry, dark container — that keeps it stable for over 2 years. Once reconstituted, it should be used within days if refrigerated at 0-4°C; we don't recommend freezing solutions.
