I'm reaching out to inquire about your Urolithin A powder. Specifically, I'm interested in purchasing a kilogram for our needs. Could you please provide me with the price per kilogram and the associated shipping costs to my location? Additionally, it would be helpful if you could share any bulk pricing options or other details regarding bulk orders, as we may consider larger quantities in the future. I'm also curious about the product's specifications, including its purity level and any available Certificates of Analysis. If you have packaging options, please include those details as well. Quick response would be appreciated, as we're looking to make a decision soon. Thanks!
