Dieng Kratom is excellent. I first purchased a kilo of the Dieng White. It has a nice energizing effect. Then I ordered the Dieng Red Bali, Yellow Maeng Da, and Green Maeng Da. The Green Maeng Da is very very potent. Be careful not to take too much or you will definitely get the wobbles! I take half the dose I ususally take of his Green Maeng Da because it is so strong. I like to mix it with the Red Bali to soften the effects a bit. It gives me a great amount of energy, so I like to take it in the morning with my coffee, along with some Red Bali. I am alert and ready to go to work! I work in a cube and am on the computer all day. The Green Maeng Da helps keep me focused and productive throughout the morning. I concentrate better when I take kratom. For a more mellowing effect, I often mix it with the Yellow Maeng Da. Or another great mix is to mix 2 parts Red Bali to 1 part Yellow Maeng Da. It is very soothing and relaxing. If I am at work and need to maintain my alertness, I mix in some Dieng White as well. The other strain I have had from Dieng Kratom is Red Borneo. I love Red Borneo! The effects are hard to distinguish between the Borneo and the Red Bali. But I like to switch things up to avoid stagnant strain syndrome and building a tolerance. If you are debating what strains to get, I find an affordable combination is 3 kilos with free delivery! To get started, I would recommend the Green Maeng Da, the Red Bali or Red Borneo, and the Yellow Maeng Da. The Yellow Maeng Da is my favorite. Some vendors have a yellow that gives energy. I find Dieng Kratom's yellow to fall more into the classic "mellow yellow" category. To finish, let me say that the owner provides excellent customer service and the amount of time it takes to arrive from when I order it to when I pick it up is really not much longer than ordering from an American vendor. Andika, the owner, also provided me with photos, a couple video clips, and information on where the leaves he uses originates from. It's fund to get to know an actual Indonesian vendor and learn more about how the kratom is processed and where the leaves come from. It's also so much cheaper to buy directly from the producer in Indonesia! If you want to have fun with your kratom experience, you have come to the right place! Buy Dieng Kratom! You won't be disappointed! Dwight Brown, Saratoga Springs, New York
