There are alternative OTC products available, suggest investigating revenues for this and similar products before contemplating theories that Big-Pharma is worried and working to limit Biel's products from wider availability.
Rational evaluation would deduce, Big-Pharma is not concerned and if they were they would have made the Biel family an "Offer they could not refuse"
Reality is this company appears to be 10-20% product based to establish 80-90% Stock selling channel. SEC has filed legal action and request the Biel family to respond to accusations with the intent of protecting further harm to investors.
