New to peptides? Start with the basics.
Understand the terms, read labels with more confidence, and know what a research finding actually tells you.
No science background needed. This guide introduces the language used across our Research Library.

Three ideas to know first
01 / BUILDING BLOCKS
What is a peptide?
A peptide is a short chain of amino acids joined by peptide bonds. Amino acids are also the building blocks of proteins. The order of those building blocks helps define the molecule. [1]
02 / IDENTITY
The details matter
A familiar name is a starting point. Check the exact compound, form, amount, and preparation before comparing a label with a study or laboratory report.
03 / EVIDENCE
A finding has limits
A result in a laboratory experiment answers a particular question. It does not automatically tell us what happens in people, or describe a different product. [4]
Common questions, plain answers
How are peptides different from proteins?
Both involve chains of amino acids. “Peptide” generally describes a shorter chain; proteins are made from one or more longer chains folded into structures. The name alone does not tell you the molecule’s properties. [1]
Does every compound in a peptide catalog count as a peptide?
No. Catalogs can also contain other kinds of research compounds. Look at the individual material’s identity rather than assuming everything in the same category is chemically alike. Our Research Library separates compound identities.
What does “research use only” mean here?
Serum Research supplies catalog materials for laboratory and analytical research, not for use in people or animals. A research-use label is not a drug approval or proof of clinical safety. See our general FAQ.
Is a research compound the same as an approved medicine?
Do not assume that it is. An ingredient name shared with a medicine does not establish that another material has the same formulation, manufacturing controls, or approval. Check the exact drug product and its labeling in official FDA records. [2]
What do mg, mcg, mL, and mg/mL mean?
mg and mcg measure mass: 1 mg equals 1,000 mcg. mL measures volume. mg/mL describes concentration: mass per volume. These are different quantities. A labeled amount is not, by itself, a recommended dose. Our performs laboratory calculations using entered values; it does not select a dose.
What is a COA, and what should I check?
A certificate of analysis records tests and results for an identified material or batch. Match the lot code and compound to the label, then read the methods, results, dates, and any limits. A report for a different lot is not a substitute. Read the certificate guide or browse available lab reports.
Does a high purity percentage tell me everything?
No. Identity, purity, quantity, and microbial testing answer different questions. A purity result alone does not establish sterility, the amount in the container, clinical safety, or effectiveness. Check which measurements the report actually includes. [3]
How should research materials be stored?
Use the documentation for the exact material and preparation. Do not apply one generic storage temperature or shelf life to every compound. If documentation is missing or unclear, ask our team for the available information.
Can this guide tell me which peptide to take?
No. It explains research terminology and evidence, not personal treatment choices. Questions about medicines or a health condition belong with a qualified healthcare professional.
Before trusting a research headline
Start with these four questions:
- What was studied? Find the exact material, not just a similar name.
- Where was it studied? Distinguish a cell experiment, an animal study, and research involving people.
- What was measured? Read the actual outcome and comparison, rather than only the headline.
- What remains uncertain? Look for limitations, mixed or negative findings, and whether other studies support the result.
