The documentation is the evidence. This is how to read it.
Certificates, chromatograms, citation identifiers and pharmacokinetic notation are the material research actually arrives in — and all of it is written for people who already know how to read it. These guides work through the technical detail behind peptide research so the documents in front of you become something you can check rather than something you have to take on trust.
Why we write these
Research material comes with paperwork, and the paperwork is where the useful information is. A certificate names a method and a batch. A paper carries an identifier that leads back to the study that produced a number. A reported half-life belongs to a species, a route and a sampling window. None of that is difficult once someone has explained the conventions — and almost nobody does, because within a laboratory the conventions are assumed.
We publish batch certificates, cite literature by PMID and DOI, and show pharmacokinetic values with the population each one was measured in. It would be a strange thing to publish all of that and leave the reading of it to chance. These guides are the other half: what the fields mean, what each method can establish, and where a document stops being evidence and starts being an assumption.
They are written for laboratory research. They cover interpretation, terminology and documentation — not applied use, and not guidance for humans or animals.
Start here
The three that make the rest easier to read.
How to Read a Peptide COA
How to read a Certificate of Analysis: batch identity, HPLC purity, identity confirmation, and what the document cannot tell you about your material.
Read the guideCalculator FormulaPeptide Reconstitution Calculator Formula
Research-use explanation of peptide reconstitution calculator formulas for concentration, draw volume, and U-100 syringe unit references.
Read the guideStorage GuidePeptide Storage Guide
What 2-8 °C and -20 °C actually mean, why cold slows deamidation and oxidation, how lyophilised and reconstituted material differ, and what to record.
Read the guideWhat reading it properly gets you
Four things the library is built around.
- Traceability
- A batch number, a certificate and a test date should join up into one record you can follow. Knowing which fields carry that link is the difference between holding a document and being able to check it.
- Analytical clarity
- Purity and identity answer different questions, and a method reports one of them. Understanding what an analysis measured tells you what it can and cannot establish about the material in front of you.
- Literature literacy
- A citation with an identifier can be opened and checked; one without is a claim about a paper rather than a reference to it. The same applies to a figure quoted without the population it was measured in.
- Practical reference
- Concentration arithmetic, storage conditions and preparation records are ordinary laboratory work. Written down properly, they stop being the part of a protocol that gets reconstructed from memory.
The library
17 guides in 6 groups. The order runs outward from the documents that arrive with material, to the methods behind them, to the literature and reference work that everything else is checked against.
Certificates, specifications and records
The paperwork that arrives with material: what each document is evidence of, what none of them can establish, and how a batch identifier ties an analysis to the vial it describes.
How to Read a Peptide COA
How to read a Certificate of Analysis: batch identity, HPLC purity, identity confirmation, and what the document cannot tell you about your material.
Read the guideDocumentation GuideCOA, SDS and Specification: Three Documents, Three Questions
A certificate reports what one batch measured, a specification what material must meet, a safety data sheet hazard. Three documents, three different questions.
Read the guideDocumentation GuideBatch Numbers, Lot Traceability and Chain of Custody
How a batch number links material to the analysis describing it, what a traceable record must contain, and where documentation stops being evidence about your vial.
Read the guideAnalytical methods and what they measure
The analysis behind the documents — how each method separates, detects and reports, what a number produced by one of them actually claims, and where its floor sits.
How to Read an HPLC Chromatogram
How to read a chromatogram: what the axes, peaks and baseline show, how area percentage is calculated, and why one large peak is about separation, not identity.
Read the guideAnalytical GuideHPLC and LC-MS: Purity and Identity Are Different Questions
What chromatographic separation measures, what mass detection adds, and why HPLC and LC-MS answer different questions rather than replacing one another.
Read the guideAnalytical GuideWhat "99% Purity" Actually Means
Purity is not one measurement. Area percentage, assay content, water and residual solvent answer different questions, and a figure without its method hides which.
Read the guideAnalytical GuideLOD and LOQ: What "Not Detected" Actually Means
Detection limit and quantitation limit describe a method, not a sample. What each one means, how they are established, and why not detected never means absent.
Read the guideAnalytical GuideHow Analytical Methods Are Validated
What validation demonstrates: accuracy, precision, specificity, range and robustness, how they relate, and why validated does not mean every batch was tested.
Read the guideScientific literature and references
Finding, reading and checking published research and registered studies — and the identifiers that make a citation verifiable rather than decorative.
Understanding PubMed, PMIDs and DOIs
What a PMID and a DOI each identify, how to check a citation resolves to the paper it claims, and why an identifier separates a reference from an assertion.
Read the guideLiterature GuideHow to Verify a Citation
How to verify a citation properly: resolve the identifier, confirm the record, check for retractions, and establish whether the source supports the claim.
Read the guideLiterature GuideHow to Read a ClinicalTrials.gov Study Record
What each field of a ClinicalTrials.gov record means, how registration differs from results, and why an NCT number shows a study was registered, not that it worked.
Read the guideResearch terminology and reference
The vocabulary a paper or a database entry uses, and what each term is precise about — including where two records that look like the same substance are not.
Pharmacokinetic Terms Explained
Tmax, Cmax, half-life and AUC — what each measures, how they relate on a concentration-time curve, and why a figure quoted without its population is not information.
Read the guideReference GuideChemical Identifiers: CAS, CID, SID, SMILES, InChI and InChIKey
CAS, PubChem CID and SID, SMILES, InChI and InChIKey: what each identifier actually pins down, and why two names for one substance are not interchangeable.
Read the guideReference GuideWhy Scientific Databases Disagree
Why two records for the same substance can differ in formula, mass or structure: substance versus compound records, standardisation, and provenance.
Read the guideLaboratory handling and storage
Keeping material stable, labelled and traceable from the moment a vial arrives — and reading the hazard document that arrives with it.
Peptide Storage Guide
What 2-8 °C and -20 °C actually mean, why cold slows deamidation and oxidation, how lyophilised and reconstituted material differ, and what to record.
Read the guideDocumentation GuideWhat Is a Safety Data Sheet?
A safety data sheet has sixteen prescribed sections and one job: communicating hazard. What each section covers, and why it is not evidence of purity.
Read the guideCalculations and research tools
The arithmetic behind concentration and volume, written out rather than hidden inside a calculator.
Rather work it out than read about it
The same material, as tools.
Still being written
The library grows in the directions the material does. Method validation is next — what accuracy, precision, specificity and robustness each establish about a procedure — followed by structure notation in its own right, molecular formula against molecular weight, reading a paper critically, clinical trial phases, lyophilisation and degradation pathways, and the dilution and unit arithmetic that sits under all of it.
Nothing is listed here before it is written. If a guide is not on this page, it does not exist yet.
