I'm looking to purchase some DHT Powder and would greatly appreciate it if you could provide me with pricing details for a 10g sample. Understanding the cost is essential for me to make an informed decision moving forward with a potential larger order. Additionally, if you have any information about the product specifications or relevant certificates, that would be helpful as well. Looking forward to your prompt response so we can proceed. Thanks!
