FST-344 (Follistatin-344) is a synthetic research peptide based on a naturally occurring isoform of the follistatin protein. Follistatin is involved in regulating members of the transforming growth factor-beta (TGF-β) superfamily, particularly myostatin (GDF-8) and activins, which play important roles in cellular growth, differentiation, and tissue development.
ARA-290, also known as Cibinetide, is a synthetic 11-amino-acid research peptide derived from the helix-B domain of erythropoietin (EPO). Unlike erythropoietin itself, ARA-290 was designed to investigate specific protective signalling pathways without focusing on traditional erythropoietic activity, such as stimulation of red blood cell production.
Dermorphin is a specialised research peptide originally identified in the skin secretions of certain amphibian species. It is a naturally occurring opioid peptide that has attracted scientific interest due to its unique molecular structure and interaction with mu-opioid receptors.
PT-141 (Bremelanotide) is a synthetic melanocortin peptide that has been studied for its effects on sexual desire and arousal through the central nervous system. Unlike compounds that primarily influence blood flow, PT-141 is believed to activate melanocortin receptors (MC3R and MC4R) in the brain, which play a role in regulating sexual motivation and arousal.
Kisspeptin-10 is a short synthetic decapeptide (10 amino acids) derived from the C-terminal region of the naturally occurring kisspeptin protein, which is encoded by the KISS1 gene. Despite its small size, it retains full biological activity and is widely used in scientific research to study reproductive hormone regulation.
Ipamorelin is a synthetic growth hormone secretagogue peptide that stimulates the body’s natural release of growth hormone by acting on the ghrelin receptor (GHS-R1a). It is widely studied in research settings for its selective and targeted mechanism of action compared to earlier growth hormone-releasing peptides.
