Peptide
A short chain of amino acids. Online discussions often use the word broadly, so context and documentation matter.
Amino acid
A building block associated with proteins and peptides in biological systems.
Research Use Only
A label indicating research-material context, not consumer wellness positioning or human-use instructions.
COA
Certificate of Analysis. A document that may summarize testing information such as identity, purity, or batch-related data.
Batch / lot
A production or packaging identifier used for traceability and documentation.
Purity
A testing-related term. Purity statements should be connected to documentation, method, batch, and limits — not treated as marketing alone.
Lyophilized
Freeze-dried form. This definition is informational only and not preparation or use guidance.
Blend
A combination of more than one named component. Blends require especially careful label review because names can obscure what is included.
Anecdote
A personal story. Anecdotes can be interesting, but they are not controlled evidence or medical guidance.
