BPC-157: sequence, origin and the published research
A plain-English summary of what BPC-157 is, where the sequence came from, which laboratory models it has been studied in, and why the evidence base is still considered limited.
4 min read · 4 referencesPeptide purity testing: HPLC and mass spectrometry explained
Purity and identity are the two numbers that matter most on a research peptide certificate. This guide explains how each is measured, what the figures do and do not tell you, and which impurities are typical of synthetic peptides.

A certificate of analysis is the documentary link between a vial and the laboratory tests performed on its lot. This guide explains each field you are likely to see and what a careful researcher checks.

Freeze-drying makes peptides far more stable than they are in solution, but not indefinitely so. This guide summarises the main degradation pathways described in the pharmaceutical literature and the storage practices that follow from them.

Research peptides sit outside the medicines framework only because of how they are made, sold and presented. This article summarises the UK definitions and explains why reputable suppliers are strict about research-use-only wording.

Two receptor systems control growth-hormone release from the pituitary, and research peptides have been designed against each. This article compares the GHRH-receptor analogues CJC-1295 and tesamorelin with the ghrelin-receptor agonist ipamorelin.

Two quite different peptides are often grouped as “mitochondrial peptides”: SS-31, a synthetic compound designed to reach the inner mitochondrial membrane, and MOTS-c, a peptide encoded in the mitochondrial genome. This article explains the difference.
4 min read · 13 referencesThymosin β4 and “TB-500”: what the names refer to
“TB-500” is a commercial name, not a defined chemical entity. This article explains what thymosin β4 is, which fragment the name is sometimes applied to, what the published research covers, and why the distinction matters.
