We have been making Epimedium extracts for nearly 10 years, and both the product process and the product's quality stability can be well guaranteed. We have our own R&D department as well as a testing department and a corresponding product project team. The specifications support R&D customization. Recently, 10% icariin powder, a hot-selling product, have been put into storage for nearly 2 tons of products. If you have any demand for this, you are welcome to consult.
