I've been playing with cycle combinations for about a year now, and I've really love using the Epi Test, and the support stack together. For me, it really gives me a dry look, and the intensity during my workouts is unbelievable. All the stacks are fantastic, and I'm still fine tuning what works for me, but the bottom line is, do the work, eat decent depending on your goal, and add some of these stacks to your routine, and you'll see results.
