Expert articles on the latest peptide research, mechanisms of action, and scientific findings — written for researchers and scientists.
Semaglutide is a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist that has become one of the most studied peptides in metabolic and cardiovascular research. This article examines the science behind its mechanisms and the breadth of its research applications.
Body Protection Compound 157 (BPC-157) is a pentadecapeptide derived from a protective protein found in gastric juice. Over two decades of preclinical research have established it as one of the most broadly studied repair-promoting peptides in the field, with applications spanning musculoskeletal, gastrointestinal, vascular, and neurological research.
Multiple peptide classes have emerged as important tools in fat loss and metabolic research. From GLP-1 receptor agonists to growth hormone fragments and GHRH analogues, this article reviews the most extensively studied peptides in adiposity and lipolysis research.
Insulin-like Growth Factor 1 Long Arg3 (IGF-1 LR3) is a structurally modified analogue of IGF-1 with enhanced receptor binding and a dramatically extended half-life. This article explains its molecular mechanism, receptor pharmacology, and key findings in muscle, metabolic, and cancer biology research.
Epithalon (Epitalon; tetrapeptide Ala-Glu-Asp-Gly) is one of the most studied peptides in biogerontology research. Developed at the St. Petersburg Institute of Bioregulation and Gerontology, decades of research suggest it modulates telomerase activity, gene expression, and oxidative stress in aging tissues.
Melanotan II (MT-II) is a cyclic synthetic analogue of alpha-melanocyte stimulating hormone (α-MSH) with high affinity for melanocortin receptors MC1R through MC4R. Its diverse receptor profile has generated research interest across pigmentation, photoprotection, energy regulation, and reproductive biology.
Tirzepatide and semaglutide represent two generations of incretin-based research compounds. While semaglutide acts exclusively on the GLP-1 receptor, tirzepatide is a dual GIP/GLP-1 receptor agonist. Research comparisons between these peptides illuminate the additive and synergistic contributions of each receptor system to metabolic regulation.
Wound healing is a complex, multi-phase biological process involving hemostasis, inflammation, proliferation, and remodeling. Multiple peptides have emerged as important research tools for studying and modulating each phase of this cascade, offering mechanistically distinct approaches to understanding tissue repair.
Thymosin Beta-4 (Tβ4) is a highly conserved 43-amino acid peptide found in virtually all mammalian cell types, making it one of the most abundant and versatile peptides in the human body. Its research applications span tissue repair, cardiac regeneration, neurological recovery, and immune modulation.
Hexarelin (His-D-2-Me-Trp-Ala-Trp-D-Phe-Lys-NH2; CAS: 140703-51-1) is a synthetic hexapeptide growth hormone-releasing peptide (GHRP) with the most potent GH-releasing activity among the GHRP class. Beyond growth hormone axis research, hexarelin has generated significant interest for its direct cardioprotective effects mediated through a non-GHS-R1a receptor.
