There is no doubt about it, in the world of anabolic androgenic steroids testosterone is king and in the human body itself it is an imperative hormone. Yes, there are side effects of testosterone use but they are manageable, largely preventable and often of no concern if were responsible. There is a very real risk to reward ratio that exist around exogenous testosterone use; the more we use the greater the reward but the more we use the greater the potential for negative or adverse side effects. Further and often overlooked, a healthy diet can greatly improve our odds; as cholesterol and blood pressure can be a concern we should consume diets that promote healthy levels of both.
A team led by Dr. Joel Finkelstein at Massachusetts General Hospital investigated testosterone and estradiol levels in 400 healthy men, 20 to 50 years of age. To control hormone levels, the researchers first gave the participants injections of a drug that suppressed their normal testosterone and estradiol production. The men were randomly assigned to 5 groups that received different amounts (from 0 to 10 grams) of a topical 1% testosterone gel daily for 16 weeks. Half of the participants were also given a drug to block testosterone from being converted to estradiol.
