Your goal,

Our approach
The science behind Earnest
Earnest started from a frustration most of us share — standing in a supplement aisle, or staring at a dozen bottles at home, with no real idea whether they're doing anything, whether the dose is right, or why you'd take one over another. We thought there had to be a better way to bring rigorous science to everyday decisions.
Who built this
Earnest was created by a PhD in Biomedical Engineering from Johns Hopkins University — with a research background in how compounds interact with human biology at a molecular level.
Every recommendation framework has been developed in consultation with physicians from University of Pennsylvania, Johns Hopkins, Stanford, and Massachusetts General Hospital — spanning internal medicine, endocrinology, and longevity medicine.
Shaped in close collaboration with Gianluca Sansone and Edoardo Alessandri — bringing decades of perspective from one of the most respected families in wellness and fitness.
On peptides
Peptides are one of the most exciting — and most confusing — areas in longevity medicine right now. The research is genuinely promising, but there is an enormous amount of noise: unreliable sourcing, unverified dosing protocols, and marketing that outpaces the evidence. Earnest cuts through this by citing only peer-reviewed human trials, flagging where evidence is early-stage, and being explicit about what remains unknown. We'd rather tell you "the evidence is limited" than overstate a compound's case.
A note on caution
The supplement and peptide landscape is evolving rapidly — regulations are changing, new research is published constantly, and what's available today may be classified differently tomorrow. Earnest is not a replacement for your doctor. We use data, mathematics, and the latest published research to help you ask better questions and make more informed choices — but always in conversation with a qualified healthcare provider, especially for anything outside standard OTC supplements.
