Aging and Cellular Decline

As women move through their 40s and beyond, physiological shifts in hormones, collagen synthesis, and mitochondrial efficiency can influence body composition, energy, and recovery capacity. Research into peptides—short chains of amino acids that act as biological signaling molecules—has expanded rapidly, with scientists exploring how they may interact with various cellular pathways related to aging, repair, and metabolism.

At Intrinsic Research Labs, we provide high-purity, USA-manufactured research peptides designed for laboratories and licensed professionals conducting controlled studies in the field of cellular and metabolic research.
