Research Glossary

Key terms every peptide researcher should know

🔗

Peptide

A short chain of amino acids (2–50) linked by peptide bonds. Shorter than proteins, and often more bioavailable.

📈

HPLC Purity

High-Performance Liquid Chromatography - the gold standard for measuring compound purity. >98% is research-grade.

❄️

Lyophilized

Freeze-dried powder form of a peptide. Highly stable for storage; requires reconstitution before use.

💧

Reconstitution

The process of dissolving a lyophilized peptide in bacteriostatic water or another solvent for use.

⏱️

Half-life

The time required for the concentration of a compound to reduce to half its initial value in the body.

🔑

Agonist

A molecule that binds to a receptor and activates it, producing a biological response.

🩸

Angiogenesis

The formation of new blood vessels from pre-existing ones. Key mechanism in tissue repair peptides like BPC-157.

🧠

BDNF

Brain-Derived Neurotrophic Factor - a key protein for neuronal growth and survival. Upregulated by several nootropic peptides.

GLP-1

Glucagon-Like Peptide-1 - an incretin hormone. Target of metabolic peptides like Retatrutide.

📋

COA

Certificate of Analysis - document from a third-party lab confirming purity, identity, and specification of a compound.

💉

Subcutaneous

Injection into the layer of fat beneath the skin. Common route for many research peptides.

🔋

Sirtuin

A class of proteins involved in cellular regulation, DNA repair, and aging - activated by NAD+.
