There appears to be some brand confusion, as the term "American Natural Peanut Butter Sugar Free 340G" could refer to a few different brands that are available in that size and format, particularly in markets like Pakistan (where many of the search results originate).

Here is a summary of the information found, focusing on similar products:

1. "American Garden" or "American Harvest" Peanut Butter (340g)

"American Garden" and "American Harvest" are brands that offer 340g peanut butter jars.

The product is often described as having an authentic American taste.

Caution on "Sugar Free": While some varieties may be labeled "Natural" and free of artificial colors/preservatives, the search results for the standard "American Garden" product in this size often list sugar as an ingredient: Peanuts, sugar, hydrogenated vegetable oil (rapeseed, cottonseed and soybean oils), and salt. You would need to specifically confirm the "Sugar Free" or "No Added Sugar" label on the packaging, as the base product may contain sugar.
