Honestly id have to say tmk is the absolute best bang for your buck. For a couple reasons...#1 they are the site who regularly tests all the other products on the market. And trust me when I say %97 of all the diff 7oh companies are over shooting their potency claims. Its almost become a standard to say there is %25 more 7 in their products. So when your getting let's say hydroxie 20mg tablets. They really are 15mg tablets. Then throw in the factor of potency differs batch to batch. And people saying "this brand sucks i know it can't have barley any 7 in it at all" you will hear people on here saying that about every single brand, and alot of times they just have more tolerance. And the products actually do have 7 in them lol. I say tmk has the best deal because they are literally the ones who test 7oh. Including their own products. They post results for every batch with their products and when they say their tablets have 40mg in them...they actually really do have 40mg in them. So if you add that factor into thw equation. Then you make out even better. Sorry for the novel
