Used it for just a few days and noticed partial erectile dysfunction and complete stoppage of ejaculation. I have stopped using it and will observe. Hopefully, the effect is temporary.
I was near the lower end of the reference levels for B12. Within 2 weeks of starting this supplement - 1 tab daily - I noticed some improvement in my sleep-wake cycle.
Looks like it is going to last me for the next few years! The dosage is very small.
Very good introduction
