A frequently asked question: “My order sat in the mailbox for a day. Is the material still good?” The short answer: freeze-dried peptides are made to cope with that.
Why lyophilisate can handle transport
Without water, the main degradation processes proceed very slowly. As a result, a lyophilised peptide in a sealed vial stays stable for several days to weeks at room temperature. That is more than enough for shipping within Europe.
What to watch out for
- Extreme heat: a parcel left for hours in full sun or in a hot car can lose quality faster. So collect your parcel as soon as possible.
- Moisture: the vial is sealed, but don’t let the parcel get wet.
- In solution: once dissolved, a peptide is far more sensitive. That is why we always ship as a powder.
What to do on receipt
- Check that the vials are intact and properly sealed.
- Note the batch number and the date of receipt.
- Put the vials in cool storage straight away: 2–8 °C for short term, −20 °C for long term.
How we ship
Orders received before 17:00 leave the same working day from the Netherlands. They are shipped discreetly packed, with track & trace, and usually arrive within 2–4 working days in most EU countries. Shipping within the EU is free from €100 or from 2 vials.
