Thanks. Can you tell us who they are, what and where they sell?
Yes they do. Not all products are available due to restrictions put in place by this bill in 2016 > "The Psychoactive Substances Act 2016 ('the Act'): defines 'psychoactive substance' and makes it an offence to produce, supply, offer to supply, possess with intent to supply, import or export psychoactive substances (the maximum penalty is seven years' imprisonment)." Whilst this may sound like they're selling serious drugs lol it's not, it's an over arching bill covering substances that the UK consider harmful and restricted. I can only think of two items they sell which are in this category, and they shouldn't be imported as they would be confiscated. For example Agmatine is restricted but personally I do not consider it a harmful supplement but that's law so you'd be unwise to break it.
Do they sell to the UK?
How, OK well I know of one company in the USA which has heavily invested in in-house testing and reference standards. They are transparent and probably the best in the world at what they do. In fact they're so good they are now being certified for creating their own reference standards by which other manufacturers can utilise. They create and sell products which are tested well beyond the current standards of the general supplement industry. It's because of their knowledge and description of their processes that I have a general distrust of the general supplement industry because they've highlighted all too well the huge failings of this industry. They set out to change the industry and be the best and no one is doing what they are currently.
It definitely feels like an unregulated mess....but how do you navigate it?
