BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in gastric juice. It has been extensively studied for its potential regenerative and protective properties in various tissue types.
TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4, which plays a crucial role in tissue repair, cell migration, and blood vessel formation in the body.
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin levels.
CJC-1295 is a synthetic analog of growth hormone releasing hormone (GHRH) with a Drug Affinity Complex that extends its half-life significantly compared to native GHRH.
Semax is a synthetic peptide derived from adrenocorticotropic hormone (ACTH). It was developed in Russia as a nootropic and neuroprotective agent with applications in cognitive enhancement research.
GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. It has been extensively studied for wound healing, skin rejuvenation, and tissue remodeling.
Semaglutide is a long-acting GLP-1 (glucagon-like peptide-1) receptor agonist that mimics the incretin hormone GLP-1, regulating blood glucose levels, appetite, and body weight through multiple metabolic pathways.
Tirzepatide is a first-in-class dual GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptor agonist, providing synergistic metabolic effects for diabetes and obesity research.
Retatrutide is a first-in-class triple hormone receptor agonist targeting GLP-1, GIP, and glucagon receptors simultaneously, producing the most profound metabolic effects seen in obesity research to date.
Orforglipron is an oral non-peptide GLP-1 receptor agonist developed by Eli Lilly, representing a breakthrough in weight management and type 2 diabetes treatment by enabling once-daily oral dosing of a small molecule that mimics incretin hormone activity.
Survodutide is a dual glucagon and GLP-1 receptor agonist developed by Boehringer Ingelheim and Zealand Pharma, investigated for obesity, type 2 diabetes, and metabolic dysfunction-associated steatohepatitis (MASH).
Cagrilintide is a long-acting acylated amylin analog developed by Novo Nordisk, designed for once-weekly subcutaneous administration and studied both as monotherapy and in combination with semaglutide (CagriSema) for obesity and type 2 diabetes management.
