Yeah the red one feels quite heavy as far as kratom goes, its my favourite right now. Although I must say the best buzz I got was a mixture of the kasungs. Just made a very strong cup of kratom tea with my red and yellow and not gonna lie its kinda knocking me sideways lmao, not sure if withdrawing from actual opiates is making me more sensitive to kratom, but I'm not complaining. The green one is very uplifting and quite euphoric overall im very happy with em and excited for my new ones
