Both <a href="http://www.t-nation.com/store/products/rez-v"target=“new”>Rez-V and <a href="http://www.t-nation.com/store/products/alpha-male"target=“new”>Alpha Male boost testosterone levels, but use different mechanisms of action.
Rez-V (resveratrol) is primarily an anti-estrogen, acting as an estrogen antagonist while also acting as an agonist in some tissues, similar to the drugs clomiphene and tamoxifen. Rez-V also acts as an aromatase inhibitor. That means that it stops the body from “eating up” your natural testosterone. Likewise, it keeps environmental estrogens – xenoestrogens, found everywhere these days, from plastics to drinking water – from artificially lowering your natural T levels and making you want to buy purple skinny jeans. (There’s no study on that second part, but we have a theory…)
In short, it keeps you from producing too much estrogen, which keeps your testosterone levels optimized and protected. As a bonus, Rez-V is a potent health and longevity supplement with anti-cancer and cardiovascular benefits. Many take it daily for these health benefits alone. It doesn’t need to be cycled.
<a href="http://www.t-nation.com/store/products/alpha-male"target=“new”>Alpha Male is a dedicated testosterone booster. It contains multiple ingredients proven to increase testosterone levels. (The store page goes over each of these.) A couple of these also prevent any problems associated with excess estrogen. Alpha Male does need to be cycled.
So Alpha Male is our most powerful testosterone booster. That’s its main purpose and our “heavy hitter” in that regard. Rez-V can optimize testosterone levels by controlling estrogen and blocking environmental estrogens, plus it has several bonus health benefits. You can use both at the same time or you could could use Rez-V between Alpha Male cycles to make sure you’re always topped off with T.
Hope that helps.
