Great question! Peptides are simply chains of amino acids (the building blocks of proteins) linked together. Think of them like beads on a necklace, where each bead is an amino acid.

When amino acids join together, they form what’s called a peptide bond. This happens when the amino group (–NH₂) of one amino acid connects with the carboxyl group (–COOH) of another, releasing a tiny water molecule in the process.

Vial sizes vary depending on the specific peptide – each product page clearly shows what’s available. Common sizes include 2mg, 5mg, and 10mg, though some peptides come in other amounts.

Just head to the product you’re interested in and check the size options. If you need a specific amount that isn’t listed, feel free to get in touch – we might be able to help!

Yes, and there’s a good reason for it! All our peptides contain a small amount of mannitol – it’s not filler, it’s actually essential for keeping your peptides in top condition.

Why we use mannitol:

• Protects during freeze-drying: Mannitol prevents peptide chains from clumping together and maintains their structure during the lyophilisation process
• Makes reconstitution easier: When you add water, mannitol helps the peptide dissolve more smoothly and completely
• Shields from moisture: It acts as a protective barrier, drawing environmental moisture away from the delicate peptide molecules
• Gives visible bulk: Without mannitol, a 5mg peptide would be almost invisible – the white powder you see is mostly mannitol, with the actual peptide dispersed throughout

Important to know: The actual peptide powder at 5-10mg is often invisible to the naked eye! The mannitol provides visible volume so you can confirm there’s product in the vial. This is standard pharmaceutical practice for all lyophilised peptide products.

Our minimum order value is £10 – that’s it! We’ve kept it low so researchers can order exactly what they need without being forced to over-purchase.

We completely understand why you’re asking, but unfortunately we cannot provide direct advice or guidance on peptide usage, dosing, reconstitution protocols, or research methodologies.

Why we can’t advise:

• We’re a supplier, not a research consultancy or medical provider
• Our peptides are sold strictly for research purposes only
• Usage protocols vary enormously depending on specific research objectives
• Providing guidance could be misinterpreted as encouraging non-research use, which would put our licensing at serious risk

What you should do instead:

1. Conduct your own research before purchasing – make sure you understand what you’re working with
2. Review published scientific studies and peer-reviewed journals (PubMed is an excellent resource)
3. Consult reputable research sources and institutional guidelines
4. Be cautious with online forums – much of the information shared is anecdotal, inaccurate, or based on hearsay rather than science

Our role vs. Your role:

What we do:

• Supply high-quality, verified research peptides
• Provide transparent quality documentation
• Ensure safe, compliant shipping
• Answer questions about product specifications and storage

What you’re responsible for:

• Understanding the product and its research applications
• Designing and conducting your own protocols
• Ensuring compliance with all applicable laws and regulations
• Using peptides only for legitimate research purposes

We hope you understand – we’re here to support your research by providing quality products, but the research itself is in your hands!
