For the most part, staying power is based on several factors. The following are some of the key ones to keep in mind: 1. Strength and Size: The strength of the products in a list should always be considered, and not just their price point. When shopping for a product for a man, it is important to understand that it doesn't have to be as heavy as it could be. If you want a strong and healthy erect penis, it is not necessary that the product be of a massive size and cost. In general, a very small size is most suitable, as the product will have a high degree of impact. 2. Purity of Ingredients and Use of Organic Ingredients: These two factors are the most important ones. A product should not have the harmful components in it. For example, there are people who are afraid to use pesticides or fertilizers on their property, because of the effect they have on plants and other animals. But there are many other products which may also be harmful to animals and plants, which are not allowed by the local health department. When it comes to ingredients, we have to be very careful.
