Zestra is a low-dose combination testosterone supplement. The testosterone in this combination comes from two sources: Testogen, a natural testosterone booster from New Zealand, and Testosterone Cypionate, a synthetic testosterone that is also known as "Tropic Pro-T" or "Vitamin-X".
Zestra has an excellent safety record. Most companies are more concerned with the safety and long-term side effects of the drug than they are with the long-term effectiveness of the drug, and often times the safety record is much worse for the company's own products.
The one significant problem with Zestra is that it does not contain synthetic testosterone. This is a very important issue because testosterone is one of the most important hormones in male life. Testosterone is a sex hormone. It is responsible for everything from the physical strength to the ability to be a sportsman. If we take the same hormones in pills, there is no way that these hormones will be the same throughout life. Most people are interested in a quick boost of testosterone in their testosterone levels, but not all. Zestra is for people who want to keep their testosterone in high levels over the long term.
Some people don't want to change the hormones in their body, so they are just taking a testosterone booster. This can be a good option for people who are just starting out.
