Pagoclone has not been approved for medical use by the FDA or other health regulatory agencies. It is still in the research and development stage and not available for purchase on the market.
It is not in production yet. Also, speech therapists do not have medical degrees and can not prescribe medicine.
I buy my research chemicals from Syntharise.com and they ship with 24 hours and ship worldwide depending on where you're located. They include the H-NMR which is a bonus. Nice selection of rare chems for a low price and Pagoclone is one of them.
