About this compound
Semaglutide
Long-acting GLP-1 analogue
Half-life
≈ 7 days
First disclosed
2012
Semaglutide is a 31-residue GLP-1 receptor agonist engineered with an albumin-binding side chain that extends its plasma residence to roughly one week. It is the most-cited GLP-1 analog in the 2020–2025 literature.
Binds the GLP-1 receptor with high affinity; studied in vitro for GLP-1 receptor-signalling pathways.

Semaglutide is a long-acting GLP-1 receptor agonist analogue, supplied by MyPeptides for laboratory research use only.
Semaglutide is a 31-residue GLP-1 receptor agonist engineered with an albumin-binding side chain that extends its plasma residence (C₁₈₇H₂₉₁N₄₅O₅₉, CAS 910463-68-2). It is the most-cited GLP-1 analogue in recent literature and the standard single-receptor reference.
Supplied as a 5 mg lyophilised vial for laboratory research, it is the natural control when comparing multi-receptor compounds such as tirzepatide, mazdutide and retatrutide.
Store at −20 °C, protected from light, and reconstitute immediately before in-vitro use. Dispatched the same working day when ordered before 12:00 UK time. Not for human or veterinary use.

Quality packaging, quick dispatch
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.

Fast UK shipping
Documentation is what sold me. Independent CoA per batch, clean HPLC traces. Reconstitution behaved exactly as expected. Solid supplier for research use.

Arrived quickly, well protected
Shipping to mainland EU took 3 working days, tracked the whole way. Vials arrived intact, labels crisp, seals unbroken. Reordering next month.

Professional service end to end
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.
