I'm an avid user of Kratom, preferring Bali but I do take my fair share of Maeng Da. I received my first batch of White Vein Indonesian Kratom yesterday and it didn't take long for the first experiment to be underway. I toss n washed 10 grams with orange juice. Not much happened in the first 45 minutes and I was starting to become dissapointed, but then the slow build up began. As the 2 hour mark approached I was in an intense nod, the type where you almost fall of the toilet, and couldn't see straight. I had no choice but to lie down and enjoy the opium dreams, which is reminiscent of my early days of Kratom use. I got up around the 3 hour mark since some friends were coming over and was still completely messed up, and heavy effects lasted until about 4 hours after dosing, which is much longer than Bali. Light to moderate opiate feelings lasted at least 2-3 more hours, hard to gauge exactly since I started casually drinking at that point. It seems that White Vein Indonesian is stronger gram for gram than Bali, and the opiating effects last longer (which might just be the result of taking in more alkaloids per dose). This was somewhat surprising since white vein kratom is supposed to be more stimulating and red vein (Bali) is supposed to be more sedating, but I think that's a broad generalization, every strain of Kratom is a hybrid of stimulating and opiating effects, and these effects change with the dose. 10 grams of White Vein Indonesian is probably quite a large dose, amateurs shouldn't take more than 5 grams of this strain at first. The potency of White Vein Indonesian is probably comparable to Maeng Da, but Maeng Da is definitely more stimulating.
