What Is a Peptide? Structure, Function and Why It Matters in Research
A plain-language primer on what peptides are, how they are built from amino acids, and why short chains of residues occupy so much of modern research.
Understanding Peptide Purity: What 99% Does and Doesn’t Tell You
A purity figure is a chromatographic ratio, not a statement about everything in the vial. What the number measures, what it leaves out and how to read it.
What Is HPLC and How Does It Measure Peptide Purity?
HPLC separates a peptide from its impurities on a column and reports the result as a chromatogram. Here is how it works and how to read one on a COA.
BPC-157 vs. TB-500: Different Mechanisms, Overlapping Research Interest
One is a gastric peptide acting through VEGFR2 and nitric oxide; the other is a fragment of an actin-binding protein. A side-by-side reading of the evidence.
Research Peptides Explained: What “Research Use Only” Actually Means
Where the RUO label comes from, how FDA views unapproved drugs and intended use, and why research peptide suppliers ask for researcher affirmations.
Why Third-Party Lab Testing Matters for Research Peptides
A supplier grading its own product is a conflict of interest, not a quality system. What independent testing adds, what it cannot fix, how to read it.
Mass Spectrometry: How a Peptide’s Identity Is Confirmed
Purity tells you how much of a sample is one thing. Mass spectrometry tells you what that thing is. Here is how the identity check works.
BPC-157 and the Nitric Oxide System
The most persistent theme in BPC-157 research is its interaction with nitric oxide. What the rat and cell studies show, and what remains inference.
Lyophilization: Why Research Peptides Ship as Freeze-Dried Powder
Freeze-drying removes water by sublimation at low temperature, leaving a porous solid that resists the chemical reactions that degrade peptides in solution.
Net Peptide Content vs. Purity: Two Numbers, Two Different Questions
A vial can be 99% pure and 75% peptide by weight at the same time. Counter-ions, bound water and how amino-acid analysis resolves the difference.
How Research Peptides Are Made: Solid-Phase Peptide Synthesis Explained
How a peptide is built one amino acid at a time on a resin bead, why Merrifield's method won a Nobel Prize, and where impurities enter the process.
