Peptides
What peptides actually are, how the major research compounds work, and how to read the science without the hype. Reconstitution, storage and purity, explained plainly.
About this classroom
Peptides are short chains of amino acids - the same building blocks that make up proteins, only much smaller. In the body, many act as signalling molecules: chemical messages that tell cells what to do. This classroom treats peptides as a subject to understand rather than a product to buy. You will learn what they are, how researchers study them, and how to tell a solid claim from a shaky one.
Where the evidence stands: The evidence base varies enormously from one peptide to the next - a few are well studied in humans, many only in cells or animals. We say which is which rather than lumping them together.
What you will learn
- What a peptide actually is - The chemistry in plain terms - amino acids, sequences, and why size changes how a molecule behaves.
- How to read the research - The difference between a test-tube result, an animal study and a human trial - and why that order matters.
- Purity, HPLC and COAs - What a certificate of analysis measures, what the percentages mean, and where marketing outruns the data.
- Handling and storage - Why reconstitution, temperature and light exposure change a compound, explained from first principles.
Curriculum
What are peptides
Start here - what peptides are, and how to judge the science before you trust a claim.
Compounds
How the major research peptides are grouped into families, and what each family is actually studied for.
Compound guides
One page per compound: what it is, the mechanism as far as it is understood, exactly how far the human evidence goes, and its legal status. Graded honestly - most of these sit far lower on the evidence ladder than the marketing suggests.
Dosing & protocols
How peptide dosing actually works - units and concentration, how a protocol is put together, and why the same compound turns up at very different doses across the research. Educational, and always alongside a qualified professional.
Handling & quality
The science of handling from first principles - reconstitution, storage and stability - plus how to read a certificate of analysis so you can tell what a vial actually contains.
Frequently asked
- Are peptides the same as steroids?
- No. They are a different class of molecule with different mechanisms. Some peptides influence hormonal pathways, but "peptide" is not a synonym for "anabolic steroid".
- Does this classroom tell me what to take?
- No. It is educational material about how peptides work and how the science is done. It is not medical advice, and it does not recommend or supply anything.
- What does "research use only" mean?
- It signals that a compound has not been approved as a medicine for human use, and that any data comes from a research context rather than clinical practice.
