We have one simple goal: to be The Best. Certified Peptides was originally founded as a subsidiary of owner Jason’s successful weight-loss peptide venture, Way Less. As demand grew and the research landscape evolved, Jason expanded the company’s vision from a weight-loss–focused operation into a comprehensive, all-encompassing research-driven organization—and Certified Peptides was born. Since its inception, our commitment to scientific innovation, rigorous testing practices, and exacting quality standards has shaped everything we do. By pairing cutting-edge research with an ethical, human-first, traditional style of business, we’ve steadily earned our position as the #1-reviewed research peptide company online. It took blood, sweat, tears, countless working hours, and relentless dedication to get here—and we’re only just getting started.

We are deeply committed to exceptional service, and your satisfaction—both with our products and with your overall experience—is our highest priority.
