Sold as 10-vial kits · minimum order

We don't sell single vials. Every order is a sealed 10-vial research kit — it's how serious labs and long-protocol researchers actually buy, and it's how we keep quality and price honest.

  • ✓ Lower €/mg — batching 10 vials cuts our fill cost, and we pass it to you (per-vial price is 40–60% lower than typical single-vial pricing).
  • ✓ One batch, one COA — all 10 vials come from the same HPLC-verified lot, so your data stays consistent across a full study.
  • ✓ Real supply for real protocols — a 10-vial kit covers ~30–90 days of research depending on dose, so you're not re-ordering mid-study.
  • ✓ One shipment, one customs pass — fewer parcels = lower risk, lower shipping cost per vial, faster to your bench.

What is Semaglutide?

Semaglutide is a long-acting GLP-1 receptor agonist derived from the native human GLP-1 sequence with structural modifications that confer resistance to DPP-4 degradation and high-affinity albumin binding. In laboratory research it is widely used as a reference compound for incretin signaling, β-cell function assays and CNS appetite circuit models.

Mechanism of action

Selective agonism of the GLP-1 receptor modulating insulin secretion and gastric emptying.

Primary research areas

Glycemic regulation, appetite signaling, metabolic studies.

Research notes

  • Frequently paired with cagrilintide in dual incretin/amylin research protocols.
  • Published rodent and in-vitro work focuses on β-cell preservation and hypothalamic POMC signaling.
  • Albumin binding extends systemic exposure and supports once-weekly dosing models.

Semaglutide: expanded research context

Semaglutide is a long-acting GLP-1 receptor agonist. It slows gastric emptying, augments glucose-dependent insulin secretion and suppresses appetite via central GLP-1 signalling. Its half-life of approximately seven days supports once-weekly protocols and has made it the most extensively studied GLP-1 to date across metabolic, cardiovascular and neuro-degenerative endpoints.

Semaglutide is the reference molecule for Ozempic, Wegovy and Rybelsus. Beyond metabolic control, published outcome trials extend to major adverse cardiovascular events (SUSTAIN-6, SELECT), heart-failure symptom burden (STEP-HFpEF) and chronic kidney disease progression (FLOW). Newer readouts examine MASH and Alzheimer's disease.

  • SELECT: cardiovascular outcomes in adults with obesity

    New England Journal of Medicine · 2023

    In adults with pre-existing CVD and overweight/obesity without diabetes, semaglutide reduced MACE by 20% versus placebo over median 3.3 years.

  • STEP-HFpEF: semaglutide in obesity-related HFpEF

    Semaglutide improved KCCQ symptom scores, 6-minute walk distance and weight in adults with HFpEF and obesity.

  • FLOW: semaglutide in T2D with CKD

    New England Journal of Medicine · 2024

    In adults with T2D and CKD, semaglutide reduced a composite kidney and cardiovascular outcome by 24% versus placebo.

What researchers say about Semaglutide

    COA matched batch number exactly

    Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.

    Fast UK delivery, clean reconstitution

    Discreet packaging, arrived in 48 hours to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.

    Best documentation I've seen from a supplier

    We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.

    Prof. L. RomanoMilan, Italy

    Good product, customs took an extra day

    Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.

    K. PetersenCopenhagen, Denmark
  • Verified

    Independent lab agreed with stated purity

    We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.

    Dr. S. PatelBirmingham, UK
  • Verified

    Cold chain held the whole way

    Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.
