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+.
