Of the many drugs to increase potency, it is necessary to choose only those whose effectiveness has been proven in clinical trials and well-proven by the consumer. Based on these criteria, we present 3 groups of drugs to improve erectile capabilities:

The drug begins to act approximately 25 minutes after administration, and retains its activity for about 5 hours.

But there are a number of shortcomings, forcing some men to abandon this product. The following side effects may occur from taking Viagra: headache, heartburn, facial flushing, etc. It is also not recommended to take the remedy more than once a day.

Which drug to choose?

The drug should be selected based on the goals that are pursued. If you need to get a short-term effect, not more than a couple of times, then cheap Viagra is what you need. If you need to spend a long time remaining sexually active, then Cialis is your choice. If it became necessary to take drugs on a regular basis, Levitra or Ziden, which have less severe side effects, would be preferable to other drugs.

But before turning to synthetic drugs, it is necessary to try natural methods to increase potency. First, it is necessary to eliminate the causes of reduced potency . Secondly, it is necessary to do special exercises that increase potency . Thirdly, it is necessary to lead a healthy lifestyle, first getting rid of bad habits. If taking pills can not be avoided, then try to increase the potency at the same time with the help of pills and natural methods. The effectiveness of this treatment will be much higher and over time, the need for tablets will be less or completely disappear.
