What is — Semaglutide
Semaglutide is a synthetic GLP-1 (glucagon-like peptide-1) receptor agonist peptide analogue, supplied by Peptworks as a lyophilized 5 mg vial for laboratory research use only (RUO). It is a research reagent characterised to >=98% purity by HPLC with an independent per-batch Certificate of Analysis. It is not a medicine, supplement, cosmetic or medical device, and is not intended for human or animal consumption.
In research models, semaglutide acts as an agonist at the GLP-1 receptor, a class B G-protein-coupled receptor. Structural modifications relative to native GLP-1 are associated in the literature with resistance to DPP-4 enzymatic degradation and extended plasma stability in preclinical systems. Receptor engagement is studied in the context of cyclic AMP signalling and downstream incretin-related pathways in cell and animal models.
Research
- In-vitro GLP-1 receptor binding and activation assays
- Preclinical models of glucose homeostasis and insulin secretion
- Animal models of appetite regulation and energy balance
- Studies of peptide stability and DPP-4 resistance
- Receptor signalling and cyclic AMP pathway research
- Formulation and lyophilization stability studies
Advantages
- Characterised to >=98% HPLC purity for reproducible in-vitro and preclinical work
- Independent per-batch CoA (HPLC + heavy metals) supporting experimental traceability
- Lyophilized format for extended shelf stability in laboratory storage
- Batch-level QR-to-CoA traceability verifiable on request
- Consistent reference material for GLP-1 receptor research programmes
Safety
- Not applicable to human or animal use; for laboratory research only.
- In published animal-model research on GLP-1 receptor agonists, reduced food intake and body-weight changes are commonly reported endpoints.
- Gastrointestinal-related endpoints such as delayed gastric emptying are frequently described in preclinical literature.
- Handle as a laboratory reagent using appropriate PPE; consult the safety data sheet before use.
Ideal for
- GLP-1 receptor pharmacology research
- Preclinical metabolic and incretin research programmes
- Peptide stability and analytical method development
- Academic and industrial R&D laboratories requiring documented reference material
- Resellers building a branded research-peptide catalogue
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.

Frequently asked questions
Where can I buy Semaglutide in bulk in the EU?
Peptworks supplies Semaglutide (GLP-1) 5mg lyophilized vials as a B2B wholesaler with stock already inside the EU. Orders ship intra-community in 3-5 business days with no customs. Material is Research Use Only and is not sold to end users.
What is the wholesale price per vial for Semaglutide?
Semaglutide 5mg has two public per-vial prices: €28.90 in a 4-vial pack and €18.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Do you offer Semaglutide as white-label?
Yes, in the white-label sense: Semaglutide comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the Certificate of Analysis verified?
Every batch ships with an independent CoA covering HPLC purity (>=98%) and heavy metals. The box QR links to that specific batch's CoA, verifiable through Peptworks, so a reseller and their customers can confirm the exact material received.
How do I pay and how fast does it ship?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. no cards are processed on site. Because stock is already inside the EU, orders ship intra-community in 3-5 business days with no customs handling.
