General Questions
What are peptides?
Peptides are short chains of amino acids linked by peptide bonds. They are smaller than proteins and play diverse roles in biological processes, acting as hormones, signaling molecules, and more. Our peptides are for research purposes only.
Are your peptides for human use?
No. All products sold by Peptide Biologics are strictly for research and laboratory use only. They are not intended for human consumption, diagnostic, therapeutic, or any other purposes.
How should I store my peptides?
Lyophilized (freeze-dried) peptides should be stored at -20°C to -80°C in a desiccated environment. Once reconstituted, they should be stored at 2°C to 8°C for short-term use or aliquoted and stored at -20°C to -80°C for long-term storage to avoid freeze-thaw cycles. Please refer to our "Peptide Storage" guide for detailed instructions.
How do you ensure the purity of your peptides?
We employ rigorous quality control measures, including High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis, to confirm the purity and identity of our peptides. A Certificate of Analysis (CoA) is provided with each product.
What purity levels do you offer?
We offer various purity levels, typically ranging from >90% to >98%, to meet different research requirements. The specific purity level for each product is listed on its product page and CoA.
Where are your peptides manufactured?
Our peptides are proudly manufactured in the USA, adhering to strict quality control standards and utilizing advanced synthesis techniques.
