Research-focused guides on peptides, testing, and laboratory handling from Vero Labs. Everything here is written for research use only – compound background and lab context, no dosing or human-use claims.
Start here
- What Is a Peptide? A Plain-English Guide – the basics: what peptides are, how they differ from proteins, and why purity matters in research.
Compound guides
- Retatrutide (R3TA) in Research: What It Is and Why It’s Studied – the triple-agonist (GLP-1/GIP/glucagon) peptide at the centre of next-generation metabolic research.
- Tesamorelin in Research: What It Is and Why It’s Studied – the GHRH analogue studied for visceral fat and the GH/IGF-1 axis.
- Tirzepatide in Research: What It Is and Why It’s Studied – the GLP-1/GIP dual-agonist behind Mounjaro / Zepbound research.
- Semaglutide in Research: What It Is and Why It’s Studied – the first-generation GLP-1 receptor agonist (Ozempic / Wegovy).
- MOTS-c in Research: What It Is and Why It’s Studied – the mitochondrial-derived peptide studied in metabolic and exercise research.
- Semaglutide vs Tirzepatide vs Retatrutide: A Research Comparison – the three generations of GLP-1 / incretin research peptides, compared by receptor target.
- BPC-157 in Research: What It Is and Why It’s Studied – the synthetic pentadecapeptide behind tissue-repair and gut research.
