There's a pretty easy way to get past your problem actually and it doesn't require more gear, etc.
- Remove a day from your lifting schedule and simply rest on that day.
- Dont cruise on 600 mg, not needed. Half that amount. A cruise is a cruise, that's a small cycle. Your cruise should be time for your lipids to get closer to range, blood pressure to drop, and a host of other physical attributes to even out, while not losing gains. You don't need more than 300 mg for that.
- Diet hard for 8 weeks. I mean hard. Forget about your ego and the scale. Think of it as priming your body for what's to come next.
- Jump back on your 10 week cycle, bump your calories from carbs and fat, and pound the weight like a fucking beast.
I guarantee by utilizing this rebound effect you'll blast past your current stats, look better and hold weight at a significantly leaner body composition. Try it, you won't regret it I promise.
