Velia Labs — 2026 Edition
All of our peptides are laboratory compounds intended solely for in vitro scientific research and analytical development. They are neither medicines nor supplements and must never be consumed by humans or animals. By placing an order you confirm that you are acting within a regulated professional or academic setting.
Every batch is analysed by HPLC (high-performance liquid chromatography) to confirm a purity of 99% or higher. Molecular mass is additionally verified by mass spectrometry. These checks ensure the consistency and reproducibility that reliable research work depends on.
Yes. An independent third-party certificate of analysis (COA) accompanies every batch. The document details the HPLC results, the mass-spectrometry identification and the matching lot number. You can review it before purchase or request it at any time at contact@velialabs.com.
We ship across France and the wider European Union with full tracking and neutral, discreet packaging. Confirmed orders are typically prepared within 24 to 48 business hours. For sensitive compounds, cold-appropriate packaging can be arranged to protect product integrity throughout transit.
In their lyophilized (powder) form, peptides are best kept away from light, moisture and heat, ideally in a freezer. Handle vials with clean gloves and reseal them promptly to limit exposure to ambient air. These general handling notes reflect good laboratory practice and are not usage instructions of any kind.
Reconstitution means dissolving the lyophilized powder in a compatible solvent suited to the intended research protocol, following your laboratory's own procedures. The solvent and working concentration depend entirely on your experimental design and must be determined by the responsible researcher. We do not provide any dosing guidance or administration protocol.
Testimonials

“Purity confirmed above 99% on the third-party COA, batch after batch. My results are finally reproducible.”
“Every vial ships with a verifiable certificate of analysis. That transparency makes all the difference for our work.”
“Fast, discreet shipping that arrived in perfect condition with careful packaging. Genuinely dependable service.”
From the lab
High-performance liquid chromatography separates the compounds in a sample so the share of the target peptide can be estimated against impurities. Here is how to read a chromatogram without getting lost.
An independent certificate of analysis documents the identity and purity of a batch. We break down the key sections of a COA and what each figure actually tells you.
Lyophilized material stays stable longer when kept cold, dry and shielded from light. A quick walk through good storage habits at the bench and in the freezer.
