Astragalos testosterone is a chemical found in male bodies that helps boost muscle and reduce fat.
The drug is used to treat conditions like obesity, heart disease and prostate cancer, and its usage is widely regarded as safe.
But a new study by a team at the University of Michigan found that testosterone can also cause serious health issues, including cardiovascular disease.
They looked at testosterone levels in over 500,000 men who took testosterone injections.
While the researchers were able to determine that men with a higher testosterone level had higher rates of heart disease, obesity, type 2 diabetes and hypertension, they found that a similar rate of heart attack and stroke was seen in those with a lower testosterone level.
It’s unclear how much testosterone is involved in the cardiovascular risk, and the researchers do not know how much of the drug is needed to increase the risk.
“The risk of cardiovascular disease was lower in those men who were taking testosterone,” said lead author Dr. David W. Wojcik.
“This was not true for men who had low testosterone levels.”
The findings were published online this week in the American Journal of Public Health.
The study was conducted by researchers at the Karolinska Institutet in Sweden and the University Health Network in the United Kingdom.
The researchers analyzed data on 1,800 men who received testosterone injections in Sweden, England, Germany, France and the United States.
The average age of the participants was 46.
Researchers also found that men who also had diabetes were more likely to have cardiovascular disease and to have heart attack or stroke than men who did not.
“We were not able to rule out the possibility that these cardiovascular events were not caused by the testosterone-induced increase in the risk of heart attacks and strokes,” Dr. Wajcik said in a statement.
The new study did not find a link between testosterone and any of the other health issues studied in the study.
Wadhwa said the results of the study could be of interest to people who have had testosterone injections, as it could help them understand whether testosterone is safe.
“One of the things we need to do is understand the risks associated with testosterone, the risks with other drugs and the benefits of the drugs,” he said.
“It is important to understand the risk associated with a given medication before deciding whether to use it.”
Wadhwas also said that testosterone injections may not be as harmful as people think.
“There is no direct evidence that testosterone is associated with heart attack, stroke, diabetes, or obesity,” he wrote in a blog post.
Wadjicz also wrote that men may experience adverse effects with testosterone treatment.
“Tests have shown that testosterone may have a negative effect on the quality of life,” he added.
Dr. Martin M. Lefebvre, a professor of pediatrics at the Johns Hopkins University School of Medicine, wrote in an email that he was not aware of any research to show that testosterone therapy can cause adverse effects.
But he did say that there may be some evidence that it may lead to more risk factors for certain diseases, including cancer.
“In my view, testosterone is not an optimal choice for many men with heart disease,” Dr.
