Introduction Insulin-like Growth Factor-1 (IGF-1) is a central mediator of growth hormone (GH) signaling involved in tissue growth, cellular repair, metabolic function, and proliferation. Two widely examined analogues—IGF-1 LR3 and IGF-1 DES—help researchers study how structural modifications influence receptor activation, signaling duration, and tissue-specific responses. This article outlines IGF-1 biology followed by detailed sections on LR3 and DES, written strictly from

Introduction Sermorelin is a 29-amino-acid fragment of endogenous GHRH used in research to study growth hormone (GH) pulsatility, endocrine timing, and receptor-specific signaling. It preserves the natural binding region of GHRH and produces a short-lived, physiologically aligned GHRH signal. What Is Sermorelin? Sermorelin consists of the first 29 amino acids of human GHRH. This segment contains the full receptor-binding region necessary to activate the GHRH receptor (GHRHR)

Introduction Short peptide bioregulators—also known as cytomedins—are ultrashort amino acid sequences studied for their role in regulating gene expression, cellular differentiation, chromatin structure, and intracellular signaling. Bronchogen is associated with bronchial and pulmonary epithelial research, with studies examining its effects on epithelial integrity, mucosal barrier dynamics, and cytokine expression. What Are Short Peptide Bioregulators? Bioregulators consist of

Introduction Frag 176–191 is a synthetic peptide representing the C-terminal region of the human growth hormone (GH) molecule. It does not activate the GH receptor and does not stimulate IGF-1 production. Instead, it exhibits fragment-specific behavior in adipocyte research models, particularly involving lipolytic and metabolic signaling pathways. This article examines Frag 176–191’s structural basis, receptor-independent activity, and relevance in GH-fragment research. What

Short peptide bioregulators—also known as cytomedins—are ultrashort amino acid sequences that influence gene expression, chromatin dynamics, and intracellular signaling in specific tissues. Pancragen is associated with pancreatic endocrine and exocrine regulatory pathways, making it a research tool for studying transcriptional regulation and cellular homeostasis in pancreatic tissue models. What Are Short Peptide Bioregulators? Short peptide bioregulators consist of 2–4 amino

The Body’s Built-In Defense Signal Long before adaptive immunity learns to recognize specific pathogens, the body relies on a fast, powerful system known as innate immunity. At the center of this system is a family of antimicrobial peptides — small molecules capable of destroying pathogens, guiding immune cell responses, and initiating tissue repair.Among these, LL-37 is the most extensively studied. Derived from the human cathelicidin precursor hCAP18, LL-37 is a 37-amino-ac

A New Frontier in Mitochondrial Medicine Mitochondria regulate cellular energy, stress responses, redox balance, and metabolic flexibility. As these systems decline with age or metabolic stress, mitochondrial dysfunction becomes a driver of fatigue, impaired tissue repair, and systemic metabolic decline. SS-31, also known as Elamipretide or MTP-131, is a mitochondria-targeted tetrapeptide designed to selectively target the inner mitochondrial membrane and interact with cardio

A New Direction in Cellular Energy Control Cellular metabolism is shaped by a network of nutrient-sensing pathways that regulate energy production, fat storage, and mitochondrial efficiency. While much attention has focused on AMPK activation, NAD⁺ metabolism, and mitochondrial peptides, another key regulatory node is emerging: nicotinamide N-methyltransferase (NNMT). NNMT is an enzyme involved in methylation balance and NAD⁺ availability. When NNMT becomes overactive, it dis

A New Class of Bioactive Molecules Mitochondria are traditionally described as the “powerhouses” of the cell, responsible for ATP production and energy balance. In recent years, a new perspective has emerged: mitochondria also behave as endocrine signaling hubs, releasing peptides that regulate systemic metabolism, stress responses, and cellular adaptation. Among these peptides, MOTS-c has generated significant scientific interest. Unlike most bioactive peptides encoded in th

From Inflammation to Regeneration Inflammation is the body’s first response to damage or stress — an essential defense process that, when unresolved, becomes the foundation for chronic disease and tissue degeneration. The search for molecules that can resolve inflammation without suppressing immunity has led researchers to a naturally occurring tripeptide fragment known as KPV.KPV, short for Lysine-Proline-Valine, is a minimal yet powerful sequence derived from the larger mel

The Forgotten Immune Regulator For decades, the thymus — the small gland behind the sternum — has been quietly training the immune system’s most specialized soldiers: T-cells. With age, chronic stress, or illness, this gland shrinks and loses efficiency. What follows is an immune system that’s reactive, fragmented, and often inflamed rather than balanced. Among the most interesting molecules emerging from thymic research is Thymosin Alpha-1 (Tα1) — a naturally occurring 28-am
