Why Velyx?
We built Velyx because we believe researchers deserve better — better quality, better documentation, and a supplier they can actually trust.
A market built on trust — but short on proof
The UK research peptide market has grown significantly over the past five years. More compounds are available, more researchers are working with them, and the science is developing rapidly. But the quality and transparency of supply hasn't kept pace.
Independent analysis of peptide samples across dozens of UK and international suppliers has found purity levels ranging from 82% to 100% — from the same compounds, sold at similar prices, with identical-looking documentation. Some vials contained measurable endotoxin levels. Some contained less of the active compound than stated. A small number contained none at all.
Researchers deserve to know exactly what is in the vials they work with. That shouldn't be too much to ask.
"I came to peptides through my work. As a lawyer turned sports therapist, I spend my days helping people manage injuries and supporting their long-term health. I started researching peptides several years ago and became increasingly convinced of their potential — and increasingly frustrated by how difficult it was to find a UK supplier I could genuinely trust. The COA documentation was inconsistent. The purity claims were unverified. The transparency simply wasn't there. Velyx exists to change that."
Transparency isn't a feature. It's the foundation.
Every decision we make at Velyx starts from the same question: would a serious researcher trust this? If the answer is no, we don't do it.
That means publishing our testing documentation openly — not hiding it behind a login or making customers ask for it. It means never making health claims we can't substantiate. It means operating as a registered UK company with our number on every page, not an anonymous website with a WhatsApp number.
It also means being honest about what research peptides are and what they are not. They are not medicines. They are not approved for human use. They are compounds with a growing body of preclinical evidence, available to researchers who want to study them — supplied by a business that takes that responsibility seriously.
UK sourced
We source from established UK suppliers with documented quality processes — no unverified overseas supply chains, no unknown intermediaries.
HPLC verified
Every batch is tested by HPLC analysis before going on sale. We publish the Certificate of Analysis so you can review the data yourself.
Transparently supplied
No hidden information, no vague sourcing claims. Our company registration number, testing documentation, and legal pages are all publicly available.
Research compliant
Age verified, research-use confirmed at checkout, legally reviewed content, no therapeutic claims. Compliant from the first click to the last.
Built for researchers who take their work seriously
Velyx is not a supplement shop with different labelling. We are a research-grade supplier built for people who understand what they are working with and demand documentation that matches that standard.
Whether you are an independent researcher, a sports science professional, or a laboratory sourcing compounds for in-vitro studies, our commitment is the same — verified quality, complete documentation, and a supplier you can rely on batch after batch.
