Thai police and Food and Drug Administration officers have seized alleged illegal peptide injections marketed as slimming or appetite-control pens, worth more than 52 million baht, during a raid on a house in Bang Yai, Nonthaburi.
The September 11 operation followed a complaint from a parent concerned after her daughter injected herself with a branded slimming pen. Investigators later found the product being widely offered on social media and said it had not been registered with the Thai FDA.
Metropolitan Police Bureau commissioner Pol Lt Gen Siam Boonsom and deputy commissioner Pol Maj Gen Phallop Aemla led the operation with officers from the D.S. police division and Ministry of Public Health and FDA officials.
Health Minister Pattana Promphat, Permanent Secretary for Public Health Dr Somruek Jungsaman and FDA secretary-general Supatra Boonserm were also involved in the inspection.
More than 52m baht in products seized
Officers searched a house in Sao Thong Hin subdistrict, Bang Yai district, and seized a large quantity of products. They included peptide injection products, distilled water intended for mixing with medicine, insulin needles, documents explaining how to use the products and alcohol swabs.
Authorities put the value of the seized goods at more than 52 million baht.
The injections were described by officials as illegal peptide medicines, commonly promoted online as appetite-control or weight-loss pens. The inquiry began after the parent asked D.S. police to determine whether the pen used by her daughter was dangerous or unsafe.
Claimed sales of 100 boxes a day
Police said the operation had allegedly been running for around one year. A house had been rented as a base, while migrant workers were hired to pack products and send them through private delivery firms.
Investigators said the group shipped an average of 100 boxes each day, charging 2,900 baht per box. That would produce daily sales of 290,000 baht and monthly income of more than 8 million baht from the illegal medicine sales, police said.
The alleged offence is selling modern medicines without a licence under the Drug Act of 1967. The penalty is up to five years in prison and a fine of up to 10,000 baht.
