Sounds like DMT to me. What does it smell like? It's fine for DMT to be a powder. If you were to put the powder under the microscope you'd see that it's all just crystals anyway. Sometimes people get bigger crystals if they recrystallize them or also depending on the conditions under which they scraped up the DMT in the final extraction steps as well as the solvent used and the method used for crystal recovery (evaporation vs. freeze precipitation). DMT can look so many ways, but for the most part it's all just DMT. Sometimes extra colors may come into play if there are impurities like plant fats/oils (which are harmless). You'd probably wanna get started on doing your own extraction so you know exactly what's going in and what's coming out, and you can become self-reliant. The first DMT that I ever tried matches your description perfectly though.
