The active ingredient found in Proviron is Mesterolone. This medication is only used in males due to the volume of testosterone it creates. It is too powerful for women, and it will cause harsh side effects for them including unwanted facial hair and deepening of the voice.

Reasons to use

The main use of Proviron is to replace testosterone the body isn’t create on its own. This is typical in males with Hypogonadism. The body isn’t ever going to go back to creating enough of it with this condition.

Many males use Proviron for bodybuilding and athletics. It is known to assist with reducing overall body fat. It also helps to gain muscle mass in less time. They like they definition it offers and it can help them to get ready for body building contests. It can be used both during bulking and cutting cycles. Often, it is stacked with various anabolic steroids because they tend to reduce natural testosterone levels. Adding Proviron to the stack can prevent that from being an issue to contend with.


The dose of Proviron will depend on the reason it is being taken. For ongoing use, the daily amount is very low. It should be taken at the same time each day. Don’t skip doses and don’t change your dose without the consent of your doctor. Don’t stop taking it because you are feeling better.

For males with Hypogonadism, the use of Proviron will be ongoing. If they stop taking it, their levels of testosterone will be reduced once again. This medicine isn’t going to resolve the health condition, but it can help a male to regulate testosterone. This is very important for overall health and function.

For bodybuilding and athletic use, the amount of Proviron will depend on what it is stacked with and what you plan to accomplish with it. Take your time to find the best products to stack it with and the right dose of each. Too much of it can do more harm than good.

This product is offered in a tablet form. You may need to break up your daily dose into several intervals throughout the day. Make sure you fully understand how often to take it and how much each time. This will help to regulate the testosterone levels rather than it spiking and falling. It should be taken with a glass of water. It can be taken with or without food. Some users experience nausea if they take Proviron on an empty stomach.

Possible Side Effects

Since testosterone is natural in the male body, most users of Proviron find they don’t experience any side effects. The higher the dose taken, the more likely side effects are to develop. They should offset after a few weeks during the time when the body is getting adjusted to the intake of it. Such side effects include:

  • Acne

  • Swelling of the face or lips
  • Rash
  • Itching
