We have gathered the questions researchers ask us most often about peptides and answered each one briefly. Where a topic deserves more detail, we point you to the relevant full guide.
Key points
- Peptides are short chains of amino acids that act as signalling molecules in biology.
- All our products are research reference materials, not for human consumption.

General questions
What are peptides?
Peptides are short sequences of amino acids. In biological systems they act as signalling molecules, passing messages between cells. Our introductory guide to research peptides covers the subject in more depth.
How does a peptide differ from a protein?
Mostly in size. Peptides are short chains, while proteins are longer and more structurally complex.
What does “for research use only” mean?
It means the products are sold solely as reference materials for laboratory research. They are not medicines and are not intended for human or veterinary consumption.
Storage and reconstitution
How are research peptides stored?
They are normally supplied as a lyophilised (freeze-dried) powder and kept refrigerated and away from light to protect stability.
What is reconstitution, and why is bacteriostatic water used?
Reconstitution is the process of dissolving the powder before laboratory use. It is typically carried out with bacteriostatic water, which contains a preservative that inhibits bacterial growth. Our reconstitution calculator helps with the concentration maths.
Specific compounds
What is Retatrutide?
Retatrutide is a triple receptor agonist investigated in metabolic and body-weight research. Read our full Retatrutide guide.
How do BPC-157 and TB-500 differ?
Both are studied in tissue repair research, but they are thought to act through different mechanisms. Our BPC-157 vs TB-500 comparison explains the differences.
What is the difference between CJC-1295 with and without DAC?
The main difference is the duration of activity observed in research. See CJC-1295 with DAC vs without DAC.
Ordering and store questions
What should I look for when sourcing research peptides?
Look for a supplier that provides clear product information, independent documentation and suitable packaging. Our guide to buying research peptides in the UK goes through the main checks, and you can view certificates on our lab tests page.
What about delivery, payment or returns?
Details of delivery, payment and returns can change, so please contact us directly for current information at admin@evilpeptides.co.uk.
