Research Library

Educational guides on the quality science and analytical characterization of research peptides — how material is identified, how purity is measured, and what the documentation behind each batch actually proves. Everything here is for research use only; nothing here is medical, dosing, or administration guidance.

Quality & analytical guides

Quality Science Center
Why purity is only one part of quality — identity vs purity vs net content, sterility, endotoxins, water and elemental impurities, and what a COA really proves.

How to Read a Certificate of Analysis
What every field on a peptide COA means — identity, purity, sterility, endotoxins, heavy metals — and how to tell a real independent report from a weak one.
Read →
HPLC Purity Testing, Explained
How HPLC measures peptide purity, what ≥99% means, and why purity, identity and net content are three different analytical questions.

Compound research profiles

Full Compound Library
Technical research overviews for all 35 compounds in the VP Peptides catalog — mechanism studied, molecular identifiers (CAS / formula / PubChem CID), regulatory status, and peer-reviewed references.
Browse →
Batch Verification Registry
Recent batches with third-party laboratory documentation — HPLC purity, sterility, endotoxins and heavy-metal screen verified, and every untested parameter shown openly, per batch.
Open registry →

Understanding the evidence

Catalog by Evidence Strength
Every compound grouped by how strong the human vs preclinical evidence actually is — clinically mature molecules through preclinical-dominant research compounds.
Compare →
How to Evaluate Research
Mechanism vs preclinical vs clinical evidence, the questions that separate strong studies from weak ones, and why the exact compound and formulation matter.
Read →
The Claim Checker
“99% purity,” “pharmaceutical grade,” “clinically proven,” “third-party tested” — the questions to ask before you believe any of them.
Read →
Research Map
The catalog organized by biological system — metabolic, mitochondrial, GH/IGF-1, cellular aging, tissue/ECM and neuroendocrine research areas.
Explore →
The Biology of Aging
The core mechanisms of aging — mitochondria, senescence, autophagy, telomeres, inflammaging and more — and the compounds studied in relation to each.

Innate repair & tissue-protective signaling

ARA-290 / Cibinetide
An 11-amino-acid EPO-derived peptide studied for the Innate Repair Receptor — investigational, with limited human Phase 2 data and a broader preclinical base.
Read →
The Innate Repair Receptor (EPOR/CD131)
How researchers tried to separate erythropoietin’s tissue-protective signaling from its blood-cell-forming activity.
Read →
Small-Fiber Neuropathy Research
What the small early human trials show vs the animal and mechanistic work — kept clearly separate.
Read →
Neuroinflammation & Microglia
Glial responses and neuropathic-pain models — a predominantly preclinical research area.
Read →
Ischemia/Reperfusion Biology
Why restoring blood flow can injure tissue, and the preclinical tissue-protection research around it.
