For decades, mitochondria were understood primarily as the cell’s energy generators. That understanding has since expanded significantly. Research has established that mitochondria also function as active signaling hubs — producing molecules that communicate with the rest of the cell and even with distant tissues. MOTS-c is one of the most studied of these mitochondrial-derived signals, and the research literature on it has grown substantially since its initial characterization in 2015.
Nicotinamide adenine dinucleotide — more commonly referenced as NAD+ — is a coenzyme found in every living cell and has become one of the most actively researched molecules in longevity and metabolic biology over the past two decades. A 2026 PRISMA-guided systematic review in ScienceDirect noted that NAD+ research has expanded dramatically, with studies spanning preclinical models through human interventional trials examining its role across a wide range of biological processes. This post provides a research-focused overview of what the peer-reviewed literature has explored regarding NAD+ and its decline with age.
Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide derived from prothymosin alpha, a protein produced by the thymus gland. First isolated by Allan Goldstein and colleagues in the 1970s, it has since accumulated one of the most extensive peer-reviewed research profiles of any immunomodulatory peptide in the scientific literature. This post covers what that research has actually explored — the mechanisms, the study findings, and the areas where Tα1 continues to generate scientific interest.
Tesamorelin and Ipamorelin represent two of the most extensively studied compounds in growth hormone secretagogue research. While each has been examined independently across a substantial body of peer-reviewed literature, researchers have increasingly studied them in combination based on their complementary receptor targets and mechanistically distinct pathways to GH stimulation. This post provides a research-focused overview of both compounds individually and the rationale for studying them together.
Among the most consistently studied compound pairings in growth hormone secretagogue research, CJC-1295 (without DAC) and Ipamorelin represent two mechanistically distinct peptides that have been examined both individually and in combination. This post covers what peer-reviewed literature has explored regarding each compound’s mechanism, pharmacokinetic profile, and the rationale behind studying them together.
Delta Sleep-Inducing Peptide — more commonly referenced in research literature as DSIP — is a nine-amino acid neuropeptide that has been studied across a range of neurological and endocrine contexts since its initial isolation in the 1970s. This post provides a straightforward overview of what peer-reviewed research has explored regarding DSIP, with a focus on the mechanisms and study areas most relevant to current research interest.
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a naturally occurring protein found in human gastric juice. It has gained significant attention in preclinical research due to its potential role in tissue repair, angiogenesis, and inflammation regulation.
Peptide research has entered a new era of complexity and precision. Among the compounds attracting significant scientific attention is retatrutide — a synthetic peptide that has become one of the most discussed molecules in metabolic and obesity research circles. While still firmly in the investigational stage, early studies are producing results that have prompted considerable interest among researchers worldwide.
Peptides, short chains of amino acids, have become a hot topic in biomedical research. These naturally occurring molecules, which in many cases serve as signaling factors or hormones in the body, are now being studied as tools and models for new medicinal treatments.
