The SYNER-BOOST formula of Progentra is the best ever produced for a male enhancement supplement. The formula has over 25 clinical tests that support the effectiveness of each ingredient, all published in the National Center for Biotechnology Information (NCBI). Each test proves that each ingredient in Progentra is carefully studied for its effects on libido, vasodilation, synergy, and for pro-erectile properties.
The SYNER-BOOST formula is all about the concept of ingredient synergy. Ingredient combination has been the bread and butter of the pharmaceutical industry for the last 5 decades. By combining two or more ingredients, better results are achieved. A great example would be over-the-counter migraine pills. By combining acetaminophen, a common analgesic, with caffeine, better relief is obtained from migraines instead of taking more than 2-4 times as much of the same analgesic.
Safety is also a major factor in these scenarios. Since penis enlargement deals mostly with the circulatory system, such drastic changes to blood flow could be detrimental to the health of the user. Vasodilation is the ONLY proven method to make penis enlargement a possibility. However, by flooding the body with vasodilators, you risk a massive drop in blood pressure, which is a serious and fatal health hazard to the user. To alleviate this, vasodilators are combined with aphrodisiacs and hormone stabilizers to share the load in focusing the blood flow to the penis by way of an arousal. By being more sensitive to sexual cues, the body focuses more blood to flow to the penis without overloading on vasodilators. As a result, the cavernous spaces in the penis get an increased blood volume and pressure, which leads to bigger erections.
