Z-tropin™ has been formulated to provide a potent blend for maximum effectiveness with no reported side effects and there are no known or reported drug interactions or conflicts. But as with any supplement, consult your physician prior to use.

You do not need a prescription to buy Z-tropin™. Z-tropin™ is a scientifically blended combination of all-natural botanicals, so you do not need a prescription to purchase it. As such, our product is considered a dietary supplement by the Food and Drug Administration and is therefore not regulated by current FDA guidelines.


Each spray bottle of Z-tropin™ contains a 60 day (2 month) supply.

Each spray bottle contains 60 doses. Each dose consists of 6 full sprays into the mouth (2 sprays in the morning and 4 sprays at night); thus, each bottle contains approximately 360 full sprays.

Directions for Use

Take 2 full sprays every morning and hold under tongue for 2 minutes. Take 4 full sprays at night before sleep and hold under tongue for 2 minutes. This represents the maximum recommended daily dosage.

For best results, Z-tropin™ should not be swallowed, but rather allowed to absorb through the mouth.


Store in a dry place below 30 degrees centrigrade (86 degrees fahrenheit). Avoid exposure to sunlight.

Lifestyle Recommendations

For optimum results, maintain a healthy, active lifestyle. We suggest a balanced diet coupled with regular cardiovascular exercise and strength training. We also suggest that you keep the mind sharp and focused through activities such as reading, writing or problem-solving. Furthermore, eliminate use of all tobacco products and if you drink alcohol, do so in moderation.

Try Z-tropin™. And re-discover those feelings of youth and vitality.
