Melanotan I is a synthetic peptide analog of the naturally occurring alpha-melanocyte-stimulating hormone (α-MSH) that is widely studied in laboratory research involving melanocortin receptor pathways.

Nicotinamide Adenine Dinucleotide (NAD⁺) is a naturally occurring coenzyme found in all living cells and plays a central role in cellular metabolism and energy transfer. In laboratory research, NAD⁺ is widely studied for its involvement in oxidation–reduction (redox) reactions, where it functions as an electron carrier in metabolic processes.

Retatrutide is an investigational peptide currently being studied in metabolic and endocrine research models. It is classified as a multi-receptor agonist designed to interact with several metabolic signaling pathways, including those associated with GLP-1, GIP, and glucagon receptor activity

SS-31, also known as Elamipretide, is a synthetic peptide studied in laboratory environments for its interaction with mitochondrial membranes and cellular energy systems. This small peptide has attracted attention in research focused on mitochondrial biology and the mechanisms that regulate cellular energy production.

Tesamorelin is a synthetic peptide analog of growth hormone–releasing hormone (GHRH) that is widely studied in laboratory environments for its interaction with endocrine signaling pathways. Structurally designed to mimic the activity of naturally occurring GHRH, Tesamorelin is used in research models to explore mechanisms related to growth hormone regulation and peptide-receptor signaling.
