About Us

TopWhey is part of a group of businesses operated by Nai Harn Gym. Since 2008, we have been an established retailer and wholesaler of nutritional supplements in Thailand.

We have several retail outlets in Phuket operating under our management.

Our primary purpose is to offer the highest quality supplements at the lowest possible prices to the consumer.

We are an authorized retailer for all the brands we sell. We never sell products near expiry or that are damaged. Everything we ship is stored in a climate controlled facility.

If you have any questions or concerns, please do not hesitate to contact us!
