The cardiovascular side effects of Aromasin can include high blood pressure as mentioned above; however, baring an underlying issue, genetic predisposition or generally unhealthy lifestyle most should not have a problem. Then we have cholesterol, and this can be a little tricky for the anabolic steroid user. When used alone, such as in breast cancer treatment, Aromasin should not have a statistical negative effect on cholesterol. For the steroid user, steroids can have a negative impact on cholesterol, some more than others. Data has shown that when an AI is used with an aromatizing steroid like testosterone it can exasperate the negative effects on cholesterol. When testosterone is administered at a therapeutic dose, the effect on cholesterol should not be significant. When testosterone is administered in supraphysiological doses, it can have a small impact on HDL cholesterol (good cholesterol) by reducing HDL levels. However, when an AI is used with therapeutic or supraphysiological doses of testosterone, data shows this may cause up to a 25% reduction in HDL cholesterol. Due to the possible cardiovascular side effects of Aromasin a healthy lifestyle will be imperative. Those who live a healthy lifestyle and possess no underlying conditions should not have a problem. In order to protect yourself from the cardiovascular side effects of Aromasin the following criteria should be met:
Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia . 
For the off-season athlete there is no anabolic steroid more important or beneficial than testosterone. High levels of testosterone will promote significant increases in lean muscle mass and strength. This is assuming that the individual is consuming adequate calories. Compounds like Testosterone Propionate are not magical, you will still need to feed your body enough calories. During an off-season period of growth, this means total caloric intake will need to be slightly above maintenance. This will, unfortunately, promote body fat gain. However, the key to a successful off-season is gaining lean tissue while minimizing body fat gain to the fullest extent possible. By supplementing with Testosterone Propionate you will be able to achieve this more efficiently. High testosterone levels will promote a stronger metabolic rate. This is not a license to eat like there’s no end in sight, but you should be able to make better use of your calories.
