Research peptides you can trace to the test report.

Every MosPeps vial carries a lot code, and every lot is independently tested for identity and purity before it ships.

From synthesis to your bench

Five steps, the same for every lot. Nothing ships until step three passes.

  1. Synthesis

    Solid-phase peptide synthesis by a contracted manufacturer, followed by purification.

  2. Lyophilization

    Freeze-dried into a stable powder cake, then sealed under a flip-off crimp cap.

  3. Independent testing

    A third-party lab confirms identity by mass spectrometry and purity by HPLC.

  4. Labelling

    Each vial gets the MosPeps label with compound, quantity and its lot code.

  5. Dispatch

    Packed with protective inserts in plain outer packaging and sent tracked.

Everything you need is on the label

Our vial label is designed so you can identify and verify the contents without opening the box again.

Colour-coded cap

Each research category has its own cap colour, so vials are easy to sort in storage.

Compound and quantity

Printed large on the label face, with the net quantity in the coloured band.

Lot code

Starts with MP. Quote it to request the COA for that exact lot.

Research-use statement

Every vial states it is for research use only, as required for laboratory reagents.

Seven categories, each with its own cap colour.

Common questions

More answers on the FAQ page, or ask us directly.

Are these products for human use?

No. All MosPeps products are sold strictly for in-vitro laboratory research. They are not approved for human or veterinary use, and we do not provide dosing or usage advice.

How do I get the COA for my vial?

Find the lot code on your vial label (it starts with MP) and send it to us. We'll email the test report for that lot.

How fast do orders ship?

Orders confirmed before on a business day ship the same day with tracking.

How should I store lyophilized peptides?

At −20 °C, away from light, sealed until use. Our storage guide covers the details.
