What it is

The most talked-about weight-loss drug in the world.

Semaglutide mimics the GLP-1 hormone to reduce appetite, slow digestion, and steady blood sugar. It is the molecule behind Ozempic and Wegovy.

In the STEP trials it produced roughly 15 percent body-weight loss, with the largest body of safety data of any modern weight-loss drug.

Reconstitution

It ships as powder. Here's how to prepare it.

Peptides are shipped freeze-dried for stability. You reconstitute with bacteriostatic water before use.

How we verify this batch

Every lot is documented before it ships.

Batch-specific COA

The certificate matches the exact lot you receive, with its own lot number and test date.

HPLC and Mass-Spec

Purity by HPLC, identity by mass-spec. We require both before a product goes live.

Independent re-test

Random vials go to an outside lab. If the numbers do not match the COA, the batch is pulled.

The research

What the research shows

The known GLP-1

Semaglutide is the molecule behind Ozempic and Wegovy, the most-studied GLP-1 receptor agonist in its class.

STEP program

Across the STEP trials, participants saw roughly 15% mean body-weight reduction over 68 weeks.

Widely validated

Years of published clinical data make it the most-documented entry point in weight-management research.

Before you buy

Common questions

Is Semaglutide third-party tested?

Yes. Every batch ships with a Certificate of Analysis showing HPLC purity and mass-spec identity for that exact lot, plus an independent report you can verify yourself.

How do I know it is really Semaglutide and not underdosed?

Mass spectrometry confirms the molecule matches the label, and HPLC confirms purity at 99 percent or higher before the lot is released.

How is Semaglutide shipped and stored?

It ships as lyophilized freeze-dried powder, cold and tracked. Store at 2 to 8 degrees Celsius and reconstitute with bacteriostatic water for research use.

Is Semaglutide for human use?

No. It is sold strictly for laboratory and research use, not for human consumption. Statements have not been evaluated by the FDA.
