So being a very curious boy-man, upon reading Rickochet71's comments, and assuming he was not a fake reviewer-promoter for sketchy online business sites, I decided to be naughty and order 50 x 50mg. I was VERY surprised a week later it was shoved into my mailbox hehe.
Tested them right away. The pills are homogeneous and uncoated. I was even MORE surprised that they work!!?? The active ingredient is present, I would say very subjectively between 25mg to 50mg. The pill base is most likely chalk (Calcium carbonate) and talc with colouring, common ingredients found in most vitamins and official pharmaceutical pills. Hence they taste chalky and break apart easily. They probably are also a good source of dietary Calcium.
Note: I ordered the "Hobbying" pills
