Long-form, factual reference on sequences, nomenclature, handling and related topics.
What Are Research Peptides? A UK Guide
A plain-English guide to research peptides: what they are, how they are studied in the laboratory, and how purity is verified. Research use only.
Are Peptides Legal in the UK? (2026 Guide)
How research peptides are regulated in the UK — the MHRA, the Human Medicines Regulations 2012, what “research use only” means, and importing. General info, not legal advice.
Buying Research Peptides in the UK: What to Check
A buyer’s checklist for research peptides in the UK — Certificates of Analysis, HPLC purity, cold-chain dispatch and supplier transparency. Research use only.
What Is a Certificate of Analysis (COA)?
What a Certificate of Analysis tells you about a research peptide — HPLC purity, mass-spectrometry identity, and how to read one. Research use only.
Bacteriostatic Water & Peptide Solution Stability
What bacteriostatic water is, why unbuffered solutions degrade peptides and redox cofactors, and how pH and buffers affect stability in research. Research use only.
Pre-Mixed vs Lyophilised Peptides: What the Difference Actually Means
Pre-mixed solution or freeze-dried powder — how the two formats differ on stability, shipping, shelf life and handling error, and which UK suppliers ship which. Reference material only.
GLP-1 Peptide Storage, Cold Chain and Handling
How GLP-1 receptor agonist peptides — semaglutide, tirzepatide, retatrutide — are handled in laboratory and supply settings: cold chain, excursion tolerance, and in-solution stability. Reference material only.
How to Store Research Peptides (UK)
A practical guide to storing research peptides in the laboratory: lyophilised cold storage, the cold chain, and stability once in solution. Research use only.
How the Reusable Pen Works: Click Mechanics
How the reusable 3 mL cartridge pen meters volume — the click ratchet, threaded rod, and why 1 click = 0.01 mL (300 clicks per cartridge). A research dispensing device. Research use only.
BPC-157 vs TB-500: Research Comparison
BPC-157 vs TB-500 compared for research — origin, mechanisms studied, local vs systemic focus, and why they are often researched together. Research use only.
CJC-1295 and Ipamorelin: How the Combination Is Studied
Why researchers study CJC-1295 (a GHRH analogue) alongside ipamorelin (a GH secretagogue), and what the combination lets them examine. Research use only.
What Is NAD+? (And Is It a Peptide?)
NAD+ explained for researchers: what the coenzyme is, why it is not a peptide, the metabolic pathways it is studied in, and how the NR and NMN precursors relate to it. Research use only.
How to read this index
What each part of a peptide entry means — the fingerprint, the property table, statuses, and how search works.
