Epithalon (Epitalon): Telomere and Longevity Research Guide Epithalon — also written as epitalon — is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed from the pineal gland-derived bioregulator epithalamin by Russian researchers Vladimir Khavinson and colleagues. It is one of the most frequently discussed peptides in longevity and anti-aging research, largely because of published studies associating it with […]

Tesamorelin: Visceral Fat and Body Composition Research Guide Tesamorelin is a synthetic GHRH (growth hormone-releasing hormone) analog engineered with a longer half-life than earlier GHRH peptides. It is among the few GH-axis peptides that have been studied in large, controlled clinical trials — specifically for its ability to reduce visceral (abdominal) fat. This guide examines […]
Sermorelin (GHRH Analog): Complete Research Guide for 2026 Sermorelin is a synthetic growth hormone-releasing hormone (GHRH) analog consisting of the first 29 amino acids of the endogenous GHRH (1-44). It has been a staple of growth hormone (GH) axis research for decades, prized for its physiological mechanism: rather than forcing the pituitary to release GH […]
Peptides for Anxiety and Mental Wellbeing: Selank, Semax and the Neuropeptide Research Landscape (2026) The search for new approaches to anxiety and mood research has increasingly turned to neuropeptides — short chains of amino acids that act as signaling molecules in the brain. Among these, Selank and Semax — synthetic peptides derived from naturally occurring […]
Peptides for Hair Growth: Complete Research Guide for 2026 Hair loss affects a significant portion of the population, and traditional treatments — minoxidil and finasteride — have well-documented limitations, including inconsistent results and side effect concerns. This has driven growing research interest in peptides that may influence hair follicle biology. This guide examines the most-studied […]
BPC-157 vs TB-500: Complete Comparison Guide for Tissue Repair Research BPC-157 and TB-500 (thymosin beta-4) are the two most widely researched peptides in the tissue repair and recovery niche, and they are frequently compared — and frequently stacked — by researchers. While both promote healing, they operate through fundamentally different mechanisms, affect different tissue types, […]
MK-677 (Ibutamoren): Complete Research Guide for 2026 MK-677, also known as ibutamoren, is an orally active growth hormone secretagogue that has attracted sustained research interest for its ability to stimulate growth hormone (GH) and insulin-like growth factor-1 (IGF-1) release. Unlike injectable peptides that require reconstitution and frequent administration, MK-677 is a small-molecule ghrelin mimetic taken […]
Semaglutide vs Retatrutide: Complete 2026 Comparison Guide Semaglutide and retatrutide represent two generations of incretin-based research peptides that have transformed the field of metabolic research. While semaglutide is a single-target GLP-1 receptor agonist that set the modern standard, retatrutide is a novel triple agonist targeting GIP, GLP-1, and glucagon receptors simultaneously. This comprehensive guide compares […]
Peptide Research in 2026: A Year of Acceleration The field of peptide research continues to expand rapidly in 2026, driven by advances in synthetic chemistry, analytical techniques, and biological understanding. From metabolic disease therapeutics to regenerative medicine and beyond, peptides are increasingly recognized as versatile research tools with broad applications across basic science, drug discovery, […]
Why Proper Peptide Storage and Handling Matters Peptides are delicate biological molecules that can degrade rapidly under improper storage conditions. Degradation can lead to reduced potency, altered biological activity, and unreliable experimental results. Understanding the factors that affect peptide stability and implementing proper storage and handling protocols is essential for maintaining peptide integrity and ensuring […]
