The spiciest Samyang ramen is the Buldak Hot Chicken Flavor Ramen 3X Spicy.
This flavor is notorious for its extreme heat and is known to be significantly spicier than other Samyang offerings. It's become a popular choice for spicy food challenges due to its intense flavor and high Scoville Heat Unit (SHU) rating. If you're looking for the hottest Samyang experience, the 3X Spicy version is the one to try (with caution!).
