NAD+ Research in 2026: Sirtuins, Mitochondria, and Cellular Aging Models

NAD+ Research - NAD+ Research: Sirtuins, Mitochondrial Biology, and Aging Models | Article thumbnail by Rejuven8 Peptides

Research Use Only. The information presented here is for scientific and educational purposes. These compounds are not intended for human consumption, self-administration, or therapeutic use. Introduction NAD+ research — short for nicotinamide adenine dinucleotide research — sits at the intersection of bioenergetics, sirtuin biology, DNA repair, and the molecular biology of aging. NAD+ is a […]

What Is Sermorelin? GHRH(1-29) Research Explained

Sermorelin Research - Growth Hormone-Releasing Peptide (Thumbnail by Rejuven8 Peptides)

Sermorelin — chemically designated as growth hormone-releasing hormone (GHRH) fragment 1–29 amide — represents the shortest fully bioactive analog of endogenous human GHRH known to retain the complete GH-stimulatory profile of the native 44-amino acid hormone. Since its characterization in the 1980s, sermorelin has been an important research and clinical tool for investigating the hypothalamic-pituitary-somatotropic […]

The Role of Angiogenesis in Peptide Tissue Repair Research

Thumbnail for Angiogenesis in peptide tissue repair research by Rejuven8 Peptides

Tissue repair is a coordinated biological process requiring the synchronized activity of fibroblasts, immune cells, epithelial cells, and — critically — vascular endothelial cells. Without the formation of new blood vessels (angiogenesis) to supply oxygen and nutrients to healing tissue, even the most well-orchestrated cellular repair programs will stall. Understanding how peptides influence angiogenic processes […]

What Is Selank? Tuftsin Analog Research Explained

Selank Research - Anxiolytic Peptide Studies & Information

Selank is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and the V.V. Zakusov Research Institute of Pharmacology. Derived from the endogenous immunomodulatory tetrapeptide tuftsin, Selank was engineered to retain tuftsin’s biological activity while gaining substantially improved metabolic stability. Over several decades of preclinical investigation and limited […]

What Is Ipamorelin? Selective GH Secretagogue Research Explained

Ipamorelin Selective Growth Hormone Secretagogue Research

Ipamorelin is a synthetic pentapeptide growth hormone secretagogue (GHS) that has attracted significant research interest for a defining pharmacological characteristic: it stimulates GH release from pituitary somatotrophs with a selectivity profile that closely mimics the physiological specificity of endogenous GHRH, while producing minimal co-stimulation of ACTH/cortisol, prolactin, or other pituitary hormones at GH-releasing doses. This […]
