Also relevant to this research category
NAD+ Pen
Nicotinamide adenine dinucleotide coenzyme in a pre-filled research pen for cellular-energy studies.
Compounds in this category are studied through incretin and metabolic signalling pathways, including single, dual and triple receptor agonists. These are investigational molecules: they hold no marketing authorisation in the European Union and the published record characterises mechanism rather than establishing outcomes.
Vial masses and formats differ significantly across this category, so concentration should be recalculated per product rather than carried across. Our reconstitution calculator handles the conversion. For research purposes only.
Questions about this research topic
- What does the Metabolic Research Peptides category cover?
- Compounds in this category are studied through incretin and metabolic signalling pathways, including single, dual and triple receptor agonists. These are investigational molecules: they hold no marketing authorisation in the European Union and the published record characterises mechanism rather than establishing outcomes.
- Are these products for human use?
- No. All compounds sold by Vitality Peps are strictly for laboratory research purposes and are not intended for human or veterinary consumption.
- Where do you ship to, and what does it cost?
- We dispatch from our warehouses in Spain and the Netherlands, depending on your location, with tracked shipping across the European Union, typically within 24 hours of confirmation. Average EU delivery is 1 to 3 business days. Shipping is a €10 flat rate and free on orders above €200.
- How should I store the vials?
- Lyophilised vials should be stored at -20°C, away from light. Once reconstituted with bacteriostatic water, store at 2-8°C and use within the recommended window for that compound.
Guides for this topic
- Semaglutide vs Tirzepatide vs Retatrutide: A Research ComparisonSemaglutide activates the GLP-1 receptor and has the most extensive evidence base, including cardiovascular outcomes data from the SELECT trial. Tirzepatide adds GIP receptor agonism and reported greater weight reduction with a generally milder gastrointestinal profile. Retatrutide uniquely engages the glucagon receptor alongside GLP-1 and GIP and reported the largest reductions observed to date, on a less mature evidence base. All three share gastrointestinal adverse events driven by GLP-1 activity. Material supplied by Vitality Peps is for in vitro laboratory research only.
- Retatrutide: What the Current Research ShowsRetatrutide (LY3437943) is an investigational triple receptor agonist studied at the GIP, GLP-1 and glucagon receptors. Published phase 2 work and later reviews describe the mechanism, while long term outcome data is not available. Material supplied by Vitality Peps is for in vitro laboratory research only.
- Where to Buy Research Peptides in Europe: A 2026 Buyer's ChecklistThe safest way to buy research peptides in Europe is from a supplier that stocks in the EU, publishes an independent lab report for each batch, ships in temperature-appropriate packaging, accepts regulated payment methods and states clearly that the products are for research use only. Ordering inside the EU avoids customs handling entirely.

- How to Read a Peptide Analysis ReportA peptide certificate of analysis shows what an independent laboratory found in one specific batch: identity confirmed by mass spectrometry, purity measured by HPLC, and the measured quantity against the labelled amount. Read it by checking the batch reference against your vial first, then the identity result, then the purity figure and the test date.
