I've always been under the assumption that once a person used Tren all the weaker steroids wouldn't be as effective any longer. Sort of like how your body adapts to things. I figured if you take the strongest stuff similar to if you run 1000mg/week on one cycle and run 500mg on your next cycle it may not be very effective or do much for you?

Once you take Tren are other steroids pretty much pointless and you have to always use Tren in a cycle? Similarly, if you use less of a dose on a future cycle does that mean it will be ineffective?
