The vast majority of people fail to od on orals. There is an upper limit to how much your stomach can digest in a short amount of time. I would think if you dissolved the pills into water and drank that, you may have a better chance.
But to od, most of the time you will need to inject. F used to be the way to go, but it's very hard to find now. H is more readily available, but you need A LOT to od, even if you have no tolerance, and haven't used it before. People on this forum have tried and failed to od on H, and wound up with permanent brain and nerve damage. Be careful and do your research.
