Patanjali Divya Kanchnar Guggul 80 Tablets (Pack of 2)

How does this compare to banyan botanicals kanchanar guggulu? my doctor specifically prescribed that brand, just wanted to make sure they are the sam.

How many milligrams of Guggul extract are in the product?

The tablets in this bottle are almost black. My other bottle was not as dark. Is this normal?

The picture shows a bottle with 80 tablets. is this price for two bottles, each with 80 tablets? thanks
