Buying Semaglutide — FAQs
Which Semaglutide strength should I order?
That depends entirely on your research protocol. Smaller 5–10mg vials suit shorter studies or first evaluations; larger 20–30mg vials give the best value per milligram for extended work. All are the same ≥99%-purity compound — only the quantity per vial differs.
Do you provide a Certificate of Analysis?
Yes — every order includes a third-party Certificate of Analysis confirming purity by HPLC. It's sent digitally with your order confirmation and available on request for any batch.
How fast is UK delivery?
Free UK shipping with no minimum spend. Orders placed before midday on business days are typically dispatched the same day, arriving in 1–2 business days with tracking. International orders ship at a flat fee.
Is Semaglutide legal to buy for research?
Semaglutide is supplied strictly as a research reagent for in vitro laboratory use, not for human consumption. While the branded medicines Ozempic and Wegovy are prescription-only, the compound sold here is an unlicensed research reagent. By purchasing you confirm you are a qualified researcher.
