Couldnt help put this to rest. So best case, lemon juice is not. Phosphric acid obviously haha. Im not sure if you can buy it at the store in liquid form...if not, do not get the salt...no way to convert it to a liquid without diluting it seriously. If so, grind up your shrooms, let them soak in the acid for different amounts of time. Because it is not a permanent process, it is reversible and naturally so. Reversible phosphorylation-dephosphorylation reaction occurs in every physiological process, making proper function of protein phosphases necessary for organism viability. Because protein dephosphorylation is a key process involved in cell signalling, protein phosphatases are implicated in conditions such as cardiac disease, diabetes, and Alzheimer's disease.
So know it does help, lemon juice may not be the best catalyst, but it does work at the right time interval.
