I don't know enough about the ox brand to say anything on that but if you've been dieting hard and for an extended period of time you may not get stronger even though you're on tren...will depend on how worn out and beat down your body is. Another thing to consider, our bodies are constantly changing, what worked perfect last time may not work perfect this time...the only way something will work perfectly each and every time is if all things remain constant and this is impossible.
