i have heard that running xenedrine or ac eca for 2weeks then clen for 2 weeks and so on is very effective when it comes to cutting bodyfat fast. i have been using xenedrine for about 5 weeks love the results so far but feel like it has crapped out on mein the past week,nothing has happened to change result other than shakeing up the lifting rutien a but by switching days i do stuff. im stacking it with 400mg of eq per week as well.
