What is the difference between research peptides and pharmaceutical peptides?
Research peptides sold by Pep Nation Lab are strictly for in vitro laboratory use: analytical research, cell studies, and scientific inquiry. They are NOT pharmaceutical drugs, are not FDA-approved for human or animal use, and must only be handled by qualified researchers in appropriate lab settings. This distinction is critical for regulatory compliance in Pennsylvania.
What does "Research Use Only" mean for buyers in Pennsylvania?
Research Use Only (RUO) means every product is intended exclusively for in vitro laboratory research. Products are not for human or animal consumption, ingestion, or injection, and are not FDA-approved. Purchasers in Pennsylvania are responsible for compliance with all applicable local, state, and federal regulations.
Do you provide HPLC and Mass Spectrometry reports with orders shipped to Chester?
Yes. Every peptide lot is subjected to rigorous third-party analytical testing, including High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). Verified researchers in PA can review these detailed reports to guarantee purity and molecular weight before beginning their assays.
