I would personally go more. At least 125mg, if not 150My batch is 75% 6-APB, 11.5% 4-APB, and 13.5% succinic acid according to the retailer. I was going to start with 100mg. Do you think that this would be too little? My usual MDMA dose is 120mg of pure MDMA as I haven't used empathogens (other than 2C-B) often enough to develop a tolerance.
