I always read and investigate before purchasing anything on the Internet. I have found the company nexgenlabsusa.com to my opinion is a scam. Reason for writing this compliant is because I could not contact company at a reasonable time so I decided not to buy the product. I would not recommend anyone wasting your money on a bad product (Phenterthin) because it does not work at all. If it was a good product the company would be available to its customers but They (nexgenlabsusa.com) DO NOT HAVE CUSTOMERS -THEY HAVE VICTIMS.
