Prime Sports Nutrition
FDA issued a warning letter to Prime Sports Nutrition (Fernando Arias, Bakersfield, CA) in December 2025 after reviewing the company's website and finding it was selling unapproved new drugs marketed as SARMs — specifically LGD-4033, RAD-140, MK-677, and S-23 — with claims about muscle building, fat loss, testosterone boosting, and treatment of conditions like Alzheimer's disease and androgenic deficiencies. Despite labeling some products as 'research compounds not for human consumption,' FDA determined the marketing copy established clear intent for human drug use. The firm was directed to respond within 15 working days with corrective steps, and FDA warned that failure to comply could result in seizure or injunction.
