Peptides are short chains of amino acids, which are the building blocks of proteins. They occur naturally in the human body and play a role in numerous biological processes. Synthetic peptides are recreated in laboratories for scientific research into cell biology, physiology, and biochemistry. Peptidera exclusively sells synthetic research peptides, intended for use in controlled laboratory environments.

The legal situation in the Netherlands is complex and varies per substance. Some compounds do not fall under the Medicines Act or the Opium Act and may be sold as research chemicals, provided they are explicitly not offered for human use. Other substances (including certain GLP-1 analogues) are in a legal grey or red area. Peptidera always advises buyers to verify the legal status of a specific compound for their intended research application. By ordering, the buyer declares to be 18 years or older and to use the compound exclusively for scientific research

Each product is analyzed by an independent external laboratory before sale. Purity is confirmed via HPLC analysis and molecular identity via mass spectrometry. The corresponding Certificate of Analysis (COA) is publicly available per lot number via our COA library. Peptidera only supplies lyophilized compounds, stored and shipped under cold chain monitoring.

Our products are exclusively intended for qualified researchers, scientific institutions, and laboratories operating within applicable laws and regulations. They are not intended for human consumption, self-administration, medical application, or veterinary use. Peptidera does not sell to individuals who wish to purchase the compounds for personal use. By placing an order, the buyer explicitly confirms this.

Researchers study peptides to better understand how biological processes work at the cellular level. Depending on the compound, research is conducted into tissue biology, metabolic signaling pathways, cellular migration, and receptor binding, among other things. All research data mentioned on our website comes from published, peer-reviewed scientific literature. Peptidera makes no medical or therapeutic claims.
