Semaglutide mimics GLP-1, the gut hormone released as soon as food comes in. It is a peptide of 31 amino acids that acts on the GLP-1 receptor. Under the brand names Ozempic, Wegovy and Rybelsus, Novo Nordisk has it prescribed for type 2 diabetes and obesity. What we supply stands apart from that: not a medicine, but a freeze-dried research-grade vial at ≥99% HPLC purity, dispatched the same working day from the Netherlands.

What does semaglutide stand for?

It is an agonist of the GLP-1 receptor. In medicine that property is used to lower blood sugar and curb appetite, which is why it is well known around type 2 diabetes and weight loss. In research it counts as one of the best-studied incretin mimetics, substances that mimic the gut hormone GLP-1. One thing belongs with that straight away: what BasePurity supplies is the research-grade vial for the lab, not the medicine. We make no health or weight-loss claims; here it is a research material and not intended for use in humans.

Several processes at once

As soon as food reaches your gut, it releases GLP-1. Semaglutide is designed to mimic that hormone and stay active considerably longer. Through the GLP-1 receptors it touches several processes at once in research: insulin release gets going as blood sugar rises, the stomach empties more slowly, and the satiety centres in the brain are addressed. Those three tracks together explain the attention the substance receives in medicine.

Why this is not Ozempic or Wegovy

This is the most important distinction on this page. What we sell is a research-grade vial: the pure, freeze-dried peptide for laboratory research. The registered medicines Ozempic, Wegovy and Rybelsus are something else; they go through a doctor and a pharmacy, with their own dosing, guidance and monitoring. Our vial does not replace that route and is explicitly not for human use. Researchers choose the vial precisely because they want to work from pure starting material and set the concentration themselves.

Place within the GLP-1 family

A fast-growing family of research compounds has formed around GLP-1. Tirzepatide lays a second route alongside GLP-1 through GIP, and retatrutide adds a third with glucagon. They are often compared because they act on related but slightly different parts of the metabolism. If you want to draw that comparison, tirzepatide and retatrutide sit separately in our metabolic line.

Making up the vial

You receive freeze-dried powder in a sterile vial. In research that is made up with bacteriostatic water and then stands dissolved, ready for lab use. We deliberately give no human dosing advice: which amount and approach fit follows from the study design, not from a usage dose. The details on this page, from purity to vial size and sequence, are meant for your research documentation.

Why we are firm about this

Semaglutide is a potent substance, and honesty belongs with that. Under medical supervision, side effects such as nausea, gastrointestinal complaints and reduced appetite are reported. Outside that supervision the Netherlands is seeing a rise in poisoning reports around this type of GLP-1 substance. That is exactly why we supply it as a research material only and not for consumption.

Purity decides usability

With a complex peptide like this one, usable research stands or falls on purity. Every batch therefore goes through HPLC for ≥99% purity and for identity, and leaves freeze-dried so it reaches you stable. That way you know exactly what you are holding; purity, sequence, molecular weight and CAS are in the table at the bottom of this page.
