I don't use the stuff myself Chris but these got a mention from a friend who uses them which is why I posted as they are cheap because they are on sale, my friend uses them either by adding juice to them to use throughout the day or uses them neat on a RDA for a morning dose before work and told me they are worth the money personally I think it's all subjective and what works for one may not work for someone elseSo I just let it down to what ever strength or flouvour I want to? Looks very cheap when looking at all the other websites. Can you vape the 3000mg straight or do them actually need letting down? What’s the deal with the shots compared to 100 300 500mg £40 ? Many thanks for replying
