I'm looking to source Grape Seed Extract with a focus on high quality and competitive pricing. Could you provide detailed specifications, including the purity levels and sourcing process? It would be great to get insights on any certifications you have, as well as minimum order quantities and lead times. Additionally, if you have different formulations or concentrations available, please share that info. I'm interested in establishing a long-term partnership, so any details on bulk pricing and shipping options would also be appreciated. Looking forward to your response!
