Weight & metabolic research peptides
Our metabolic range covers the incretin receptor class and the mitochondrial and enzyme-pathway references that sit alongside it. It includes single-agonist standards such as semaglutide, dual GIP/GLP-1 agonists such as tirzepatide, triple agonists such as retatrutide, and amylin analogues such as cagrilintide, together with combination blends supplied as a single lyophilised vial.
These are the references laboratories reach for when comparing receptor engagement across the class, validating chromatographic methods that must resolve closely related analogues, or running stability and degradation work. Each lot is assayed independently rather than certified from a representative batch, so the purity figure on your certificate belongs to the vial in your hand.

Weight & Metabolic Research, answered
- What is the difference between a single, dual and triple agonist reference?
- Semaglutide acts at the GLP-1 receptor alone, tirzepatide at both GIP and GLP-1, and retatrutide adds glucagon-receptor activity. Laboratories commonly hold all three so that receptor-selectivity panels have a comparator at each level of the class.
- Does every weight & metabolic research reference come with a certificate?
- Yes. Each vial ships with a certificate of analysis issued for its own lot number, showing reverse-phase HPLC purity and LC-MS identity confirmation from an independent partner laboratory.
- How quickly are orders dispatched?
- Orders that clear payment before the daily cut-off are typically dispatched within 24 hours from the UK, with tracked delivery to the United Kingdom and the European Economic Area countries we serve.
- Can these compounds be used on humans or animals?
- No. Everything in this range is an unlicensed reference standard supplied for in-vitro laboratory research by qualified professionals only. Nothing we sell is a medicine, supplement or cosmetic.
