Frequently asked
Questions, answered once.
Is it legal to buy research peptides in the Netherlands?
Yes. Research peptides are legal to buy in the Netherlands provided they are used exclusively for in-vitro laboratory research and not for human consumption. Our products do not fall under the designer-drugs ban that took effect on 1 July 2025 and are sold strictly under the condition not for human consumption.
Are these peptides for human consumption?
No. All products from Lab Peptides are supplied exclusively for in-vitro laboratory research. They are not intended for human or veterinary use, diagnostic purposes or administration. By placing an order you confirm you are a qualified researcher or equivalent end-user.
How do you verify the purity of each batch?
Every production batch is independently tested by a European third-party laboratory using HPLC for assay and mass spectrometry for identity confirmation. We retain samples of every lot and can issue a Certificate of Analysis (CoA) for the specific batch you receive.
Where do you ship and what does shipping cost?
We ship worldwide from our Dutch facility. Shipping is free on every order, regardless of destination or order size. Orders placed before 16:00 CET on working days are typically dispatched the same day via tracked courier.
Is packaging discreet?
Fully discreet. Shipments go out in plain neutral outer packaging without any Lab Peptides branding. Lyophilized products are protected with cold-chain inserts during transit.
Can I get a Certificate of Analysis (CoA)?
Yes. An independent HPLC and mass-spectrometry report is available on request for every batch. The CoA includes retention time, area percentage, m/z identification and the batch number.
How should I store peptides after delivery?
Lyophilized peptides remain most stable when stored dark and dry at 2-8 degrees Celsius. After reconstitution with bacteriostatic water, refrigerate them and use within the stability window of that specific peptide.
Which peptides are most popular for research?
By volume, semaglutide, tirzepatide and retatrutide are the most ordered GLP-1 research peptides. For tissue repair research BPC-157, TB-500 and our Klow blend are popular. For cognitive research Semax and Selank are commonly requested.
Do you offer wholesale for laboratories?
Yes. Institutional end-users can request bulk pricing, purchase orders and recurring dispatch schedules via a note at checkout.
