If you’re mainly going after stress hormones, cortisol and estrogen issues, <a href="http://www.t-nation.com/store/products/rez-v"target=“new”>Rez-V acts as a potent estrogen antagonist, and also has anti-oxidative and anti-inflammatory effects. So, REZ-V controls estrogen (men need a little of it, remember), protects you against environmental estrogens, and subsequently increases T.
<a href="http://www.t-nation.com/store/products/indigo-3g"target=“new”>Indigo-3G decreases the effects of insulin on fat and and increases the effects of insulin on muscle, meaning fat loss and muscle gain, and the ability to handle muscle-building amounts of carbs and calories. In other words, your body resists storing fat, releases and oxidizes fat-cell content (fatty acids), and preferentially pulls glucose and nutrients into muscle cells. Nutrient repartitioning, in a nutshell.
Indigo-3G also works on fat cell inflammation and all the problems associated with it. Given that C3G is derived from berries, it has other health-boosting effects as well.
For high-stress situations, look into <a href="http://www.t-nation.com/store/products/rhodiola"target=“new”>Rhodiola as well. But think of it as “medicine” – take it when you need it, then cycle off. The article will get into details.
To get to your specific question, we’d suggest Indigo-3G for the full cycle without REZ-V. Then, you can take a maintenance dose of Indigo and just take REZ-V on the other end of the day to prevent any possible interference.
But really it’s going to depend on your goals. If you mainly want to battle stress and estrogen issues, look into REZ-V and perhaps Rhodiola, which will also have some physique and performance effects. If you want more muscle and less fat, along with some health benefits, look into Indigo-3G.
