1-testosterone is classified as androgen as well as an anabolic steroid. It’s different than testosterone produced by the human body because of its chemical formula. It’s classified as a Schedule III drug in the United States, meaning that it is a prescription-only drug due to its potential for misuse. It’s been banned for over a decade. Still, determined bodybuilders continue to find it through less than reputable sources. Understanding 1-testosterone, what it does, and how it affects the human body is important to know before taking it. Buy Testosterone online here.

The human body produces testosterone hormones, but when a man is diagnosed with hypogonadism he may be recommended to take part in a hormone replacement therapy treatment program. This often employs the use of injectable or topical application of testosterone products.

The hormone as produced by the human body is a powerful hormone. So too are synthetic or commercially created forms of the hormone.

It should be noted that 1-testosterone is no longer sold as an over-the-counter supplement in the United States, banned since 2005. It ranks as one of the first anabolic steroids introduced into nutritional and dietary supplement products preferred by bodybuilders and athletes back in the day.


What makes the 1-testosterone profile different from more recent developments in test hormones is its anabolic-to-androgenic ratio (200/100). The anabolic to androgenic ratio is a term common to bodybuilders and athletes. An anabolic steroid is defined as a group of typically synthetic hormones designed to increase metabolism. Anabolic steroids are commonly misused and abused by athletes and bodybuilders to temporarily increase the size of muscles.

The term androgenic refers to a compound, such as a steroid hormone, that stimulates as well as maintains the development and maintenance of male characteristics. Testosterone is a prime example of an androgenic hormone, providing the aforementioned secondary sex male characteristics in men such as a deeper voice, growth of body and facial hair, and stronger musculature than females, among others.
When it was a popular supplement, 1-testosterone (a.k.a. dihydroboldenone) was sold as a nonprescription, over-the-counter supplement. It was most popularly used during cutting phases of bodybuilding, but because of its potential strength-enhancing capabilities, was also used by bodybuilders for bulking phases.

Because of its anabolic-to-androgenic ratio, bodybuilders and athletes didn’t need large doses to see results. One of the benefits (before it was banned) of 1-testosterone results was that it didn’t produce as many androgenic effects as other forms did. Check out the best cutting cycles here.

Any form of synthetically produced androgen (oral, transdermal, subcutaneous, intramuscular) has the potential to cause side effects. Disagreements among the medical community regarding the potential severity and degree to which some steroidal injectable solutions can cause harm continues to be debated.

However, it has been reported that high doses of androgens used long-term can contribute to cardiac and liver issues such as tumors, cancer, and liver toxicity. Dependence as well as the tendency to combine steroids with other drugs have also been noted.

Use of androgens, especially those not monitored by a physician may also contribute to a number of health issues, especially in men who already have been diagnosed with a medical condition.

One major concern is its potential to enlarge the prostate (a condition known as benign prosthetic hyperplasia). This is still under debate. High doses of androgens may also impact sperm production, although some men, depending on the dosage and frequency of the androgen steroid injections, may experience a reversal in infertility.

Women using any form of androgen may develop some male sex characteristics including hair loss, unnatural hair growth, or a deepening voice, which typically go away when the drug is discontinued, although some side effects such as changes in the voice or even enlarged clitoris in the female genitalia tend to be permanent.

Talk to your doctor about gender-specific side effects common to men and women taking androgens.

Can I Still Buy 1-Testosterone?

A number of bodybuilding websites often mention banned or illegal forms of 1-testosterone or other anabolic steroid products, but using a product, especially a hormone, for reasons other than which it was designed (to treat hypogonadism or low test levels in men that interfere with fertility and various aspects of health and wellness) is discouraged for safety reasons.


Anyone interested in taking injections or anabolic steroids needs to realize that while temporary muscle gains in regard to mass may be enhanced, those gains typically begin to disappear as soon as the drug is discontinued.

The Anabolic Steroid Control Act of 2004 included 1-testosterone for sale in its list of banned substances, and so this form of anabolic steroid continues to be banned in the United States and by numerous athletic organizations. Nevertheless, many bodybuilders and athletes look to underground labs and black-market resources for bodybuilding and athletic endeavors.
