I am looking to source Mulberry Fruit Extract (Morus Alba) with a concentration of 4:1. This extract is essential for our product line, and we're interested in learning more about your availability, quality, and pricing. Additionally, please provide information on your production capacity, lead times, and any certifications or testing you conduct on your extracts. It would be great to receive samples, if possible, to evaluate the quality before we proceed with a larger order. Thank you!
