Follistatin: The Myostatin-Binding Peptide for Muscle Research Follistatin is a naturally occurring protein that binds and neutralizes activins and myostatin — key negative regulators of muscle mass. By inhibiting myostatin, follistatin supports muscle growth pathways, making it one of the most researched compounds in muscle biology and performance peptide science. This guide reviews its mechanism, […]

LL-37: The Antimicrobial Peptide for Immunity and Tissue Repair Research LL-37 is the only human cathelicidin antimicrobial peptide, a multifunctional immune molecule with direct antimicrobial activity and broad immunomodulatory, wound-healing, and anti-inflammatory effects. It is a cornerstone of innate immunity research and a rising star in tissue repair and regenerative peptide studies. This guide reviews […]
Tesofensine: The Triple Reuptake Inhibitor for Weight Loss Research Tesofensine is a novel monoamine reuptake inhibitor that targets serotonin, noradrenaline, and dopamine transporters simultaneously — a “triple reuptake inhibition” mechanism that produced some of the largest weight-loss effects observed in clinical trials. It reached phase 3 development for obesity before development paused, and it remains […]
Mazdutide (GLP-1/GCGR Dual Agonist): The Next-Generation Metabolic Peptide Guide Mazdutide is a once-weekly dual agonist of the glucagon-like peptide-1 (GLP-1) receptor and the glucagon receptor (GCGR), developed for obesity and metabolic dysfunction. By combining GLP-1’s appetite suppression with glucagon’s energy expenditure effects, mazdutide represents a distinct mechanism among next-generation metabolic peptides. This guide reviews its […]
Cagrilintide: The Amylin Analog for Weight Management Research Cagrilintide is a long-acting analog of amylin, a pancreatic hormone that regulates appetite and satiety, developed for weight management and metabolic research. As the GLP-1 receptor agonist landscape expands, amylin analogs like cagrilintide represent a complementary mechanism — studied alone and in combination with semaglutide (cagrilintide 2.4mg […]
Humanin: The Mitochondrial Protective Peptide Research Guide Humanin is a 24-amino-acid mitochondrial-derived peptide (MDP) encoded in the mitochondrial genome, first discovered in 2001 for its ability to protect neurons from Alzheimer’s disease-related insults. It has since emerged as a broad-spectrum cytoprotective peptide with effects on mitochondrial function, inflammation, metabolism, and longevity. This guide reviews its […]
DSIP (Delta Sleep-Inducing Peptide): Deep Sleep and Recovery Research Guide DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit cerebral venous blood during sleep research in the 1970s. It has since become a central subject in sleep and recovery peptide research, with reported effects on deep sleep architecture, stress resilience, and […]
AOD9604 (HGH Fragment 177-191): The Fat-Burning Peptide Research Guide AOD9604 is a modified fragment of the human growth hormone (HGH) molecule, specifically the amino acid sequence 177-191, developed to replicate the lipolytic (fat-burning) effects of growth hormone without its growth-promoting or blood glucose effects. It has been studied extensively in obesity research and remains a […]
CJC-1295 DAC vs No-DAC (Mod GRF 1-29): The Complete Comparison Guide CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) designed to stimulate endogenous GH secretion. It exists in two main research forms — with and without Drug Affinity Complex (DAC) — which differ dramatically in half-life, dosing frequency, and effect profile. This guide […]
Cerebrolysin: The Neurorecovery Peptide Research Guide Cerebrolysin is a peptide-based neurotrophic preparation derived from purified porcine brain proteins, containing amino acids and low-molecular-weight peptides with nerve growth factor (NGF)-like activity. With decades of clinical use in Europe, Russia, and Asia for stroke recovery and cognitive disorders, it remains one of the most extensively studied neurotrophic […]
