The Mass Stack


Annihilate is a powerful estrogen blocker that will get you lean, hard and dense.

Do you ever just feel bloated or puffy? Do those last kilos just not want to budge or even just feeling lethargic and not yourself? These are clear signs of high estrogen levels in the body, which can lead to easier fat storage and a less than optimum environment to build muscle.

Luckily Annihilate contains the strongest Aromatase Inhibitor (AI) aka estrogen blocker on the market that reduces estrogen, increases testosterone and enhances sex drive. Annihilate is the perfect product for all (including natural) athletes looking to use their hormones as an advantage and maximise their results.
