I bought these vitamins after witnessing good reviews on all major websites: Amazon, ebay, etsy, even Trustpilot. However, a small research on the names of the reviewers made it clear to me that the reviews are fake and lies. First, most of them live in india or United States. The place is based in London, second most of them are around end of April start of May when this company started, what a coincidence, to promote these vitamins. Needless to mention that after one month use I have notices very little difference, still unclear to me if it is placebo. Check for yourselves and be more skeptical on rave reviews.
