The Science
What Are Research Peptides?
Peptides are short chains of amino acids — typically 2 to 50 — linked by peptide bonds. They serve as signaling molecules in biological systems, making them essential tools for studying receptor binding, metabolic pathways, and cellular processes in controlled laboratory environments.
At LifeSpanSupply, every compound is synthesized using solid-phase peptide synthesis (SPPS) and purified via reverse-phase HPLC. The result: pharmaceutical-grade lyophilized powder with verified purity of 99% or higher — ready for your research protocols.
