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.

GHK-Cu: What the Copper-Peptide Literature Shows
A plasma tripeptide found in 1973, a copper complex, and fifty years of fibroblast and wound studies. What the GHK-Cu record supports and what it leaves open.
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.
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.
Amino Acids vs. Peptides vs. Proteins: Where the Lines Are Drawn
Amino acids, peptides and proteins form one continuum of chemistry. This note explains where the working boundaries sit and why they matter in the laboratory.
