What are the dangers of using substances to alter body shape?
If you use substances to alter body shape, you could develop heart problems, strokes, tremors, heavy sweating, high blood pressure and sometimes sudden death. Though it does make you eat less, more fit or enhance your athletic performance, the results at the end are usually worse than the pros.
What it a healthier alternative?
70% of sculpting your body and making your body fit is actually eating healthy food and produce, eating less sugar and junk food. Only 30% of it is actually working out in the gym. If it was peer pressure persuading you, then stop talking and listening to those people. Also, if you want to enhance your athletic ability, you need a lot of practice to better a sport or activity.
