I've never tried Post Cycle but I tried Unleashed. I've tried a few Test Boosters the last 2 years and Unleashed was by far the best one I tried. It was the only one that actually gave me a feeling like I had more test going, I felt more energetic and a lot more confident both at the gym and just in general. Also put on 2lbs during that time and probably lost 1% bf. Might have been placebo since I was also very strict on my diet at the time, even if it was placebo though I feel like the Unleashed caused me to feel that way and be more strict so that helps.
But basically I liked Unleashed and it would probably go pretty good in PCT. I was debating throwing it into the PCT for my first cycle but I wanted to get everything from NutraPlanet to cut down on shipping costs so the Titanium XL and Divison 1 combo seemed similar enough to me.
