I've tried it, as others have said, it's shite, and the £/€/insert your currency here to mg ratio is extremely expensive. They're currently offering 30 x 15mg tablets (at least what they claim to be 15mg tabs, as others have stated, they offer no lab results as proof) for £202.94 (that's €233.68). That's £6.76 (€7.79) a tablet or 45p (52c) a gram.
