The cardiovascular Trenbolone side effects are the greatest concern. Studies have shown that this steroid can suppress good (HDL) cholesterol and increase bad (LDL) cholesterol in relatively short order. In fact, many believe that Tren is the hardest injectable steroid on your heart. You can absolutely control your cholesterol with diet and supplements. Consume as little saturated fat and simple sugars as possible, and use fish oil or omega-3 acids in therapeutic doses. If you have preexisting cholesterol issues, you should not use Trenbolone.
About 84% of adults will experience some sort of back pain in their lives.  Upper back pain, although less frequent than lower back issues, is a problem for many today. Because the thoracic spine in the upper and middle back region is not as mobile as the lower back and neck, injuries are not as common. However, upper back pain can develop due to poor posture and chronic muscle tension. If you suffer from upper back pain, then exercise,  good posture, and lifestyle changes may minimize bouts of discomfort, or even eliminate them completely.
