Research Peptide Education
What Are Research Peptides?
Research peptides are short chains of amino acids synthesised for use in laboratory and analytical research settings. They are studied for their potential interactions with biological receptors and cellular pathways. All 121 Peptides products are supplied strictly for research use only.
Weight Loss & GLP-1 Research Peptides
GLP-1 receptor agonist peptides including Retatrutide, Tirzepatide and Semaglutide are among the most widely researched compounds in weight loss and metabolic science. They are studied in relation to appetite regulation, energy balance and glucose metabolism. Available for laboratory research use only.
Recovery, Healing & Repair Research Peptides
Recovery-focused peptides including BPC 157 and TB500 are extensively studied in laboratory settings for their potential roles in tissue repair, cellular regeneration and inflammatory response modulation. These are research compounds supplied for analytical study only.
Cosmetic & Skin Research Peptides
Copper peptides such as GHK-CU are researched for their role in collagen synthesis, skin repair and cellular regeneration pathways. GHK-CU represents one of the most studied categories in cosmetic peptide research, analysed in both in vitro and laboratory models.

About Retatrutide
Retatrutide is a next generation triple agonist peptide currently being researched for weight management, metabolic health and appetite regulation. Unlike traditional GLP-1 compounds, Retatrutide targets three separate hormone receptors including GLP-1, GIP and glucagon receptors.
This triple action approach is being researched for its potential to:
Support significant fat loss research
Help reduce appetite and cravings in research models
Improve insulin sensitivity
Increase energy expenditure and metabolic activity
Assist with blood sugar regulation research
Support long term body composition research
Retatrutide has become one of the most talked about research peptides due to its potential strength and advanced mechanism compared to earlier GLP-1 compounds.
