If you try those you better believe in them and your luck, because there is no research data on their effectiveness on humans, dosages nor standardised production methods. That means it is actually dangerous to experiment with them. Also, these herbal sexual enhancers can have strong side effects. Spanish fly is actually a poison extracted from a beetle, which sensitises your urea tract by inflaming it!
Natural amino acid Arginine and pine bark extract
Arginine is an amino acid, which is the key ingredient to Nitric Oxide (NO), which the body uses to regulate blood flow – everywhere in the body! NO has been extremely well researched in hundreds if not thousands of studies. The team, which found out its usefulness to the human body was even awarded the Nobel Prize for Medicine in 1998.
The best and most effective alternative to the doctor’s note, synthetic ED doctor’s note tablets are the natural circulation (and therefore erection) enhancer Arginine in combination with pine bark extract.
My logic was that you cannot argue against a Nobel Prize as a rubber stamp. Arginine’s effectiveness as a erectile enhancer and a huge amount of other metabolic processes is undisputed and it has no side effects. In the UK these dedicated Arginine supplements with a sufficient dose and pine park extract are few and far between. However, on the continent especially in Germany and Italy there are lots of natural supplements available for erectile function; “food supplements for special medical purposes”.
