Frequently Asked Questions
Frequently Asked Questions
What are peptides?
Peptides are short chains of amino acids — the same building blocks that make up proteins in the human body. They act as biological messengers, signalling cells to perform specific functions such as tissue repair, hormone regulation, and metabolic activity. Because of their precision and the way they interact with the body's existing systems, peptides have become one of the most studied compounds in modern longevity and performance research.
What is the difference between peptides and proteins?
It comes down to size. Proteins are long, complex chains of amino acids, while peptides are shorter and more targeted. This smaller structure allows peptides to be absorbed more efficiently and to interact with specific receptors in a highly selective way — making them particularly interesting for research applications.
What purity standards do Verra products meet?
All Verra peptides are manufactured to a minimum purity of 99%, verified through third-party testing using HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry analysis. We hold ourselves to stringent quality benchmarks because the integrity of the research depends entirely on the integrity of the compound.
How do I know the product I receive is what it claims to be?
Each batch is accompanied by a Certificate of Analysis (CoA) from an independent laboratory. This document confirms the peptide's identity, purity level, and the absence of harmful contaminants. At Verra, transparency in our supply chain is non-negotiable.
How should peptides be stored?
Lyophilised (freeze-dried) peptides should be stored in a cool, dry place away from direct light — ideally in a refrigerator at 2–8°C. Once reconstituted, the solution should be kept refrigerated and used within the timeframe specified for that compound. Avoid repeated freeze-thaw cycles, as this can degrade the peptide's structure and reduce its efficacy for research purposes.
What is the correct way to reconstitute a peptide?
Peptides are typically reconstituted using bacteriostatic water or sterile water, depending on the compound. The liquid should be added slowly along the side of the vial — never injected directly onto the powder — and the vial gently swirled rather than shaken. A reconstituted solution should appear clear to slightly opalescent. Cloudiness, visible particles, or unusual colour may indicate degradation or contamination.
Are Verra peptides intended for human use?
No. All products sold by Verra are strictly intended for laboratory and in vitro research purposes only. They are not approved for human or veterinary use, and are not intended to diagnose, treat, cure, or prevent any condition or disease. By purchasing from Verra, you confirm that you are a qualified researcher and that the products will be used solely within a controlled research context.
Who should purchase Verra products?
Verra products are intended exclusively for licensed researchers, scientists, and qualified professionals operating within appropriate research settings. They are not intended for use by the general public, and should be handled only by individuals with the relevant knowledge and facilities to do so safely and responsibly.
What safety precautions should be taken when handling peptides?
Standard laboratory safety protocols apply at all times. This includes the use of appropriate personal protective equipment (PPE), working in a sterile or controlled environment, and following institutional biosafety guidelines. Peptides should be handled with care, kept out of reach of unauthorised individuals, and disposed of in accordance with applicable regulations.
All products are sold for research purposes only. Verra assumes no liability for misuse or use outside of a legitimate research context.
