Its activities included customer acquisition, advertising, lead generation and the distribution of digital content and services through online channels. The company underwent a strategic transformation and later changed its name to Protagenic Therapeutics, Inc. As part of that transition, its business focus shifted away from internet marketing toward biotechnology and the development of peptide-based therapeutics. The company’s later work has centered on treatments for stress-related and anxiety disorders. Atrinsic’s historical operations primarily served consumers and advertisers through internet-based platforms. Publicly available information about its former leadership, geographic reach and detailed operating history is limited, so a more comprehensive description of those aspects cannot be provided reliably.AI Generated.
