What MYOS does

MYOS Corp is a privately-held muscle health company that owns and commercializes Fortetropin, a proprietary bioactive ingredient derived from raw, fertile chicken egg yolk. Fortetropin's mechanism of action centers on upregulating the mTOR pathway (promoting muscle growth), downregulating the ubiquitin pathway (slowing muscle degradation), and lowering circulating myostatin levels — with clinical validation across 13 studies at institutions including UC Berkeley, McMaster, University of Kansas, University of Florida, NC State, Petaluma Equine, and Tampa. Quantified clinical outcomes include an 18% increase in muscle protein fractional synthetic rate in older adults (~66 years) versus placebo, prevention of serum myostatin rise during two weeks of limb immobilization, statistically significant mobility improvement in geriatric dogs at 6 and 12 weeks, and a +881g average lean muscle gain over 12 weeks in 67% of cats with chronic kidney disease.

The company operates four distinct go-to-market brands: YOLKED (NSF Certified for Sport, DTC e-commerce for athletes), MYOS PET (DTC pet supplements for dogs, cats, horses), MYOS VET (veterinary-exclusive closed portal with field sales), and MYOS MD (HCP-exclusive nutraceutical targeting muscle loss associated with aging, disuse, post-surgery recovery, and GLP-1 medications). Distribution is segmented by buyer type — consumer storefronts for YOLKED and MYOS PET, enterprise field sales and closed portals for VET and MD. The firm holds 12 patents (including multiple US grants in 2025 and an EU patent) protecting Fortetropin compositions, processes, and methods, plus the registered Fortetropin and YOLKED trademarks.

Revenue mechanics are supplement sales via three channel archetypes: direct-to-consumer one-time purchases, veterinarian-mediated veterinary product sales, and HCP-prescribed nutraceutical sales. No pricing, ARR, or unit economics are publicly disclosed; the company is privately held with no disclosed funding rounds, institutional investors, or parent company. Leadership consists of a CEO (Joseph Mannello), COO, CSO, Controller, and functional VPs across eCommerce, Marketing, Partnerships & Growth, and Vet Sales, supported by a four-member board that includes a pet industry CPG executive (Andy Ponte, formerly of Central Garden and Pet, Spectrum Brands, Koch Industries), a sports media executive (Tim Pernetti, American Athletic Conference), and the former CEO of PCI Animal Health (Robert Zeide).
