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. Every product has undergone independent HPLC and LC-MS testing, with representative documentation available online.

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.
- Has every weight & metabolic research product been independently tested?
- Yes. Every product has undergone independent HPLC and LC-MS testing, and certificates of analysis are available to view on the relevant product pages.
- 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.
