Tren is an extremely androgenic hormone, and as a result well known for promoting androgenic side effects. Hair loss and acne in men who are predisposed are both possible. Body hair growth is also possible. If you are not genetically predisposed no amount of Tren on earth with cause these issues. The androgenic side effects of Tren are truly based on genetic response. When it comes to hair loss, if you are predisposed to male pattern baldness, meaning at some point you’re going to lose your hair regardless of steroid use , Tren is one of the fastest ways to ensure you lose your hair a little sooner.
Virilization is a serious androgenic side effect of Tren. It is very difficult for a woman to use Tren without some level of virilization and makes it a steroid that’s almost never recommended for female use.
Important Note: The 5-alpha reductase enzyme does not metabolize the Trenbolone hormone. This means 5-alpha reductase inhibitors like Finasteride will not affect the androgenicity of the hormone.
In November 1942, the Italian cyclist Fausto Coppi took "seven packets of amphetamine" to beat the world hour record on the track.  In 1960, the Danish rider Knud Enemark Jensen collapsed during the 100 km team time trial at the Olympic Games in Rome and died later in hospital. The autopsy showed he had taken amphetamine and another drug, Ronicol , which dilates the blood vessels. The chairman of the Dutch cycling federation, Piet van Dijk, said of Rome that "dope – whole cartloads – [were] used in such royal quantities." 
Neither the age at IBD diagnosis nor the age at steroid initiation was associated with prescribing of calcium and vitamin D, and BMD testing. Likewise, gender, race, type and duration of IBD, and duration of steroid treatment were not found to be associated with prescribing of calcium and vitamin D, and BMD testing ( for each comparison by univariate analysis) (Table 2 ). However, calcium prescribing was associated with higher BMI, the year of steroid initiation, and performance of BMD, irrespective of results. Similarly, vitamin D prescribing was associated with the year of steroid initiation and performance of BMD. However, when patients with abnormal BMD results were excluded, the association of calcium ( ) and vitamin D ( ) with performance of BMD was lost, indicating that the association was driven by calcium and vitamin D prescribed for osteoporosis or osteopenia. The year of steroid initiation, type of steroid (prednisone or budesonide), and hypoalbuminemia were also associated with BMD testing by univariate analysis (Table 2 ).
