Sale framing

Research-use-only posture: FDA has consistently rejected 'research use only' labeling as a safe harbor when site evidence (dosing instructions, vials/syringes, comparisons to weight-loss drugs) shows human-use intent. Multiple Warning Letters cite this exact pattern for retatrutide.

Personal possession: Personal possession of unapproved investigational peptides sits in a regulatory gray zone. FDA enforcement focus has been on vendor-side marketing and sale, not buyer-side possession, but no formal safe harbor exists.
