I am curious as well.
Currently I'm working with R30 at a reduced intake level, ramping up from one milligram to two each week. This makes me curious about its maximum usable duration. Storage is in a refrigerator reserved solely for medications, and the container gets wiped down prior to every access. Everything was passed through a filter along with bacteriostatic water. All possible steps have been followed to maintain quality. The goal is to consume the entire amount despite the natural breakdown of such substances over time. Provided no cloudiness or visible specks appear, what's the realistic timeframe for continued use?
