I purchased a jar of 300 x 5mg tablets for about $19 at Costco, today, the first time I've seen it. I have perfomed my usual 50mg single dose. That is 1500mg for the same price as 90mg of Enzy so even if absorbtion isn't as effective, quantity might make up for it as long as the qualitative aspects are present. These are very fast dissolving so it takes some determination to keep them in place (as mush) to allow substantial absorbtion under the lip. The contain sucralose as a sweetner which isn't a sweet alcohol so many are sensitive to. It appears quite non-irritating so far. It is a natural cherry flavor. The sucralose dissolves quickly and so it starts sweet and ends a little bitter. It appears to be at least 3 stars. It's hard to tell this quickly as I only succeeded in keeping it in place for 75 minutes before fully dissolving. The percentage absorbed appears to be in the less than 5-10% category, so far, at that time span based on effects and urine colorimetry. I can feel it's body effects, so I can tell it is at least somewhat effective. I am repeating with another 50mg to see if I can get it up to that 7.5mg CNS absorbed dose, by effect and urine colorimetry. However, even if it doesn't have the critical for some of us CNS characteristics, it might make an adequate booster for the ENZY to get that into the CNS. Anybody else willing to put it through it's paces? Let me know what you think of it.
