VITROMAN 产品是如何产生效果？
VITROMAN potent herb content effects by increment of smooth muscles relaxation or vasodilation, and increase of blood flow to the private part also called Cyclic Guanosine Monophosphate (cGMP). Fact: For men who have trouble lifting his private part on its own, it is caused by Phosphodiesterase-5 (PDE 5). PDE 5 enzymes break down the cGMP. In the case of PDE 5 levels supercede the declining cGMP levels, as the private part at an upright position return to the flaccid sate. That is why holding and maintaining his private part at an upright position can be difficult for some men. The natural compound in the VITROMAN therefore effectively block out the PDE 5 enzymes, prolong manhood upright position time and better holding power.
VITROMAN 有效的草药含量通过增加平滑肌松弛或血管舒张以及增加私处血流量（也称为环磷酸鸟苷 (cGMP)）来发挥作用。事实：对于无法自行抬起私处的男性，这是由于通过磷酸二酯酶 5 (PDE 5)。 PDE 5 酶可分解 cGMP。就 PDE 5 水平而言，随着处于直立位置的私处恢复到松弛状态，PDE 5 水平取代了下降的 cGMP 水平。这就是为什么对于某些男性来说，保持和维持私处直立位置可能很困难。因此，VITROMAN 中的天然化合物可有效阻断 PDE 5 酶，延长男性直立时间和更好的握力。
