Hello
I have the same doubts and questions.
I bought the ingredients separately (which makes me take 7 pills, with more concentration per ingredient than the original TRX2 though) and I have been taking them for 1 month now.
I bought enough pills for more or less 250 days (8 month which is when the first results are supposed to shown) for about 70 pounds. I'm planning to take them for one year. I'm not taking anything else, but I'm using a ketoconazole based shampoo. Will see if it has some effect or not.
Cheers
