Storage Advice
Correct storage is critical to maintaining peptide integrity and purity. Follow these guidelines to maximise shelf life.
Lyophilised Powder (Unopened)
Store sealed vials at −20°C for routine use or −80°C for long-term storage. Keep away from light and moisture. Properly stored lyophilised peptides remain stable for 24–36 months.
Reconstituted Solution
Once reconstituted, store at +2°C to +8°C. Use within 20–30 days. Never refreeze a reconstituted solution — this causes degradation and loss of potency.
BAC Water
Store at +2°C to +25°C. Avoid freezing. Once opened, use within 28 days. Always use sterile technique when drawing from the vial.
Temperature Excursions
Brief ambient temperature exposure during transit is generally tolerable for lyophilised peptides. Avoid prolonged heat above 25°C. Contact us if you have concerns about a specific compound.
Handling & Contamination
Always handle peptides in a clean environment using sterile syringes and needles. Wear appropriate PPE in accordance with your COSHH guidelines and institutional protocols.
Research Use Only
All Pepilix compounds are for laboratory research purposes only. Not approved for human or veterinary use. Handle in accordance with all applicable safety regulations.
Laboratory Reconstitution & Handling Principles
These principles are provided for qualified laboratory personnel reconstituting lyophilised compounds within an institutional research setting. They are not instructions for individual or personal use, and do not replace your institution's own approved protocols and risk assessments.
These principles are general guidance only and do not constitute instructions for individual, personal, or non-laboratory use. Pepilix products are supplied strictly for use by qualified research professionals within a controlled institutional setting, in accordance with that institution's own protocols, risk assessments, and applicable regulations.
A Family Business, Not a Faceless Brand.
We're Ben and Hannah Davies — a husband-and-wife team who source, test, store and ship every peptide ourselves. No call centre, no anonymous warehouse. Just two people who care that you get exactly what the label says.
Started With a Simple Question
Ben spent decades in the gym testing what disciplined effort can achieve — marathons, ultra-endurance events, CrossFit, HYROX and physique training. That taught him results rarely come from shortcuts; they come from consistency, careful preparation and doing the unglamorous work properly. After building a successful technology business, he created Pepilix as a passion project with one goal: a credible, transparent research-supply company you can actually trust.
We quickly learned that purity on paper means nothing if storage and cold-chain handling aren't taken just as seriously. So we built Pepilix around getting the unglamorous parts right — proper lyophilisation, verified HPLC purity on every batch, and cold-chain shipping — before anything else.
We're a small, family-run operation by choice. It means we personally check every order, answer our own messages, and stand behind everything that leaves our door.
What Sets Us Apart
Four things we don't compromise on.
Verified Purity
Every batch is HPLC-tested to ≥99% purity. We don't sell anything we can't verify.
Proper Storage
Lyophilised and cold-chain handled correctly from manufacture to your door — not left on a shelf.
Full Transparency
Honest labelling, honest sourcing. You know exactly what you're ordering and where it comes from.
Next-Day UK Delivery
Orders placed before 2pm ship same day from our UK base.
Meet the Founders
The two people behind every order.
Ben Davies
"Meaningful results don't come from shortcuts — they come from consistency and doing the work properly."
Ben has spent decades training in gyms and testing the limits of what disciplined effort can achieve — marathons, ultra-endurance events, CrossFit, HYROX training and, more recently, physique development. That journey taught him that results rarely come from shortcuts; they come from consistency, careful preparation and a willingness to keep working when a goal initially looks impossible.
After building a successful technology business, Ben created Pepilix as a passion project with a clear objective: a credible, transparent and accessible research-supply company backed by a genuine community.
He oversees Pepilix's operations, logistics, sourcing, storage protocols and compliance. Thousands of hours have gone into researching suppliers, reviewing documentation, refining storage processes and independently testing products — the standard expected of a professional research supplier.
Pepilix is not a faceless website. Ben remains directly involved and available to answer questions.
