Wow! The link that you sent for the Optimal brand from Canadian Amazon shows that it is not currently available.
User ratings show only 62% give it 5 stars and that's pretty low.
The ingredients look good but the bottom line is that it is not available.
It appears to be the only PM product available on the Canadian website.
What a shame.
I just learned of the Amazon International Shipping Portal.
Don't know much about it but it has items that Amazon will ship Internationally.

At the top of the page, select your country first, then
type in Pueraria Mirifica in the search box, and go.
I think you will see at least a dozen different products to choose from.
I do not know anything about taxes and extra fees for you to receive your order.
You will have to investigate that before ordering.
Good luck! Let us know if this works for you.
