Educational writing on research peptides, testing methodology, and compound-specific overviews. All research-framed, never prescriptive.
New Zealand researchers working with peptide compounds need a clear understanding of the legal and regulatory framework that governs their use. The distinction between research peptides and pharmaceutical medicines in NZ is important, and the rules around sourcing, supply, and use are defined by several overlapping pieces of legislation. This guide provides an overview of […]
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is one of the most extensively studied tripeptides in the research literature. This three-amino acid peptide naturally chelates copper ions and has been the subject of research spanning tissue biology, gene expression, and cellular signalling over several decades. Its study profile is unusual in the peptide research space because of both its […]
NAD+ and NMN are two of the most studied compounds in the longevity and cellular biology research space. Both relate to nicotinamide adenine dinucleotide, a coenzyme central to cellular energy metabolism, but they occupy different positions in the biosynthetic pathway. Understanding the distinction between these compounds, and what the published research actually shows, is essential […]
Semaglutide and retatrutide represent two different generations of incretin-based peptide pharmacology. Both have been the subject of substantial clinical research, yet they operate through fundamentally different receptor mechanisms. For researchers studying the incretin system, metabolic signalling pathways, or receptor pharmacology, understanding how these compounds compare is essential. This overview covers the pharmacological profile of each […]
Proper storage is one of the most critical and frequently overlooked aspects of peptide research. A compound that arrives at 99 percent purity can degrade significantly if stored incorrectly, introducing variables that compromise experimental results and waste research budget. New Zealand researchers face specific considerations around climate, shipping duration, and laboratory infrastructure that make storage […]
Retatrutide has emerged as one of the most studied peptide compounds in metabolic research over the past several years. Unlike earlier generations of receptor agonists that targeted a single pathway, retatrutide is a triple agonist: it engages three distinct G protein-coupled receptors simultaneously. This mechanism has made it a subject of considerable interest in preclinical […]
A certificate of analysis (COA) is the primary document researchers use to verify the quality of a peptide compound before it enters the laboratory. Understanding how to read one correctly, and what to look for, is an essential skill for anyone conducting serious peptide research in New Zealand. This guide explains the structure of a […]
BPC-157 and TB-500 are among the most frequently studied peptides in preclinical research. Both have attracted significant interest for their interactions with tissue repair pathways, yet they operate through distinct mechanisms and are studied in different contexts. Understanding these differences is important for researchers designing experiments or selecting the appropriate compound for their work. What […]
Sourcing research peptides in New Zealand has become significantly more straightforward over the past few years, with domestic suppliers now offering a range of compounds with verified purity documentation and fast local delivery. However, for researchers new to the process, understanding what to look for, what to avoid, and how to ensure you are receiving […]
New Zealand researchers and laboratory professionals are increasingly sourcing peptide compounds for in vitro and preclinical study. Whether you are examining receptor binding, cellular signalling, or tissue behaviour in controlled conditions, understanding the research peptide landscape in New Zealand is essential before you begin. This guide covers what research peptides are, how the supply chain […]
You've requested a Certificate of Analysis for your peptide order: now what? Here's a practical guide to understanding what the numbers actually mean. The two key tests Most peptide purity reports include results from two primary analytical methods: HPLC and mass spectrometry. Together, they answer two fundamental questions: HPLC: Measuring purity What it is High-Performance […]
GHK-Cu is one of the most extensively studied peptides in skin science. Here's what researchers have found and why it continues to generate interest. What is GHK-Cu? GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper peptide found in human plasma, saliva, and urine. It was first identified in the 1970s by Dr Loren Pickart, who […]
NAD+ has become one of the most talked-about molecules in ageing research. Here's a grounded look at what scientists have found so far. What is NAD+? Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every living cell. It plays a central role in two critical biological processes: The ageing connection Research has consistently shown […]
CJC-1295 is one of the most popular growth hormone releasing peptides in research. But there are multiple variants — and understanding the differences matters. What is CJC-1295? CJC-1295 is a synthetic analogue of growth hormone releasing hormone (GHRH). It stimulates the pituitary gland to release growth hormone (GH) in a pulsatile manner, mimicking the body's […]
If you're sourcing research peptides, a Certificate of Analysis is one of the most important documents you can request. Here's how to read one and why it matters. What is a Certificate of Analysis? A Certificate of Analysis (COA) is a document issued by an independent laboratory that confirms the identity, purity, and quality of […]
Proper storage and reconstitution are essential for maintaining peptide integrity in research settings. Here's a straightforward guide. Why storage matters Peptides are biological molecules that degrade when exposed to heat, moisture, light, and bacterial contamination. Incorrect storage can reduce purity, alter structure, and compromise research results. A few simple precautions go a long way. Storing […]
BPC-157 is one of the most widely studied peptides in the recovery and tissue repair space. Here's what the research tells us. What is BPC-157? BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a naturally occurring protein found in human gastric juice. It consists of 15 amino acids and has been the subject […]
Research peptides are generating serious interest across the scientific community — but what exactly are they, and why are researchers paying attention? Peptides 101 Peptides are short chains of amino acids, typically ranging from 2 to 50 amino acids in length. They're essentially smaller versions of proteins, and they play critical roles in nearly every […]
