Raw-note based Vitamin B2 experience for the under-eye area. A 500 mg dose seemed very good, with noticeable smoothing around the under-eye and eye bag area within about two days.

Raw-note based Vinpocetine experience for brain fog. After about three days there was no noticeable benefit or meaningful change.

Raw-note based Piracetam experience for brain fog. It may have helped reduce brain fog somewhat, but it was not strong or reliable enough to keep using, and it caused sneezing and a runny nose similar to Berberine.

Raw-note based Berberine experience for bad breath. Two capsules with a large roti still left odor, four open capsules cut the smell substantially, and five open capsules with a large roti seemed to eliminate it.
