NAD+ is frequently discussed alongside peptides in longevity, cellular metabolism and research communities. That association creates a surprisingly common misconception: Is NAD+ actually a peptide? No. NAD+ is not a peptide. It is a coenzyme called nicotinamide adenine dinucleotide. Peptides are chains of amino acids. NAD+ has a completely different molecular structure and belongs to...Read More

One of the most immediately noticeable characteristics associated with GHK-Cu is its colour. Unlike many peptides that are commonly encountered as white or off-white materials, GHK-Cu is associated with a distinctive blue coloration. This raises a surprisingly useful scientific question: Why is GHK-Cu blue? The answer is connected to the copper ion bound by the...Read More

Tirzepatide is commonly described as a dual GIP and GLP-1 receptor agonist. That explains how the molecule acts, but it raises another basic question: Is Tirzepatide actually a peptide? Yes. Tirzepatide is a synthetic peptide-based molecule consisting of 39 amino acids and engineered to activate both GIP and GLP-1 receptors. Its structure is based primarily...Read More

Semaglutide is widely described as a GLP-1 receptor agonist, but this describes what the molecule does, rather than what the molecule actually is. So, is Semaglutide a peptide? Yes. Semaglutide is a peptide-based molecule designed as an analogue of the naturally occurring human hormone GLP-1. Its structure is based on a chain of amino acids...Read More

GLOW has become a commonly used name within peptide research discussions, particularly in areas involving skin, tissue and extracellular matrix research. But the terminology can be confusing. What is GLOW peptide? Is GLOW actually one peptide, and what does a GLOW blend contain? The most important point is that GLOW is generally used as the...Read More

KLOW 80 has become an increasingly searched term within peptide research, but the name can be confusing for anyone encountering it for the first time. Common questions include: What is KLOW 80? What does KLOW 80mg mean? What is actually contained in a KLOW blend? Unlike an individual peptide such as GHK-Cu or KPV, KLOW...Read More

KPV is an unusually short peptide that appears in experimental research involving inflammatory signalling, immune responses and gastrointestinal biology. Its three-letter name raises an obvious question: What does KPV actually stand for? KPV represents the three amino acids that make up the peptide: K — Lysine P — Proline V — Valine KPV is therefore...Read More

GHK-Cu is one of the most widely studied copper-binding peptides, appearing in research involving skin biology, extracellular matrix signalling, wound-related processes and cellular responses. But its scientific name raises a simple question: What does GHK-Cu actually stand for? GHK refers to a three-amino-acid peptide made from: G — Glycine H — Histidine K — Lysine...Read More

BPC-157 has become one of the most widely discussed experimental peptides online, but its scientific history is less commonly understood. Who discovered BPC-157, where did it originate, and why was it investigated in the first place? The story of BPC-157 is closely connected with research conducted by Croatian scientists investigating a substance referred to as...Read More

BPC-157 is one of the most widely discussed experimental peptides in research communities, but its name creates an obvious question: What does BPC-157 actually stand for? BPC stands for Body Protection Compound. BPC-157 is a synthetic peptide consisting of 15 amino acids and originates from research involving a protective compound associated with gastric juice. The...Read More
