4. Acne Problems
Increased levels of hormones make sebaceous glands work much harder and can cause acne, especially on the back. However, you’ll rarely see it on bodybuilders because in championships they use a lot of fake tan which makes acne near invisible.
5. Stretch Marks
Another factor that may help you to determine if a person uses steroids is stretch marks. Most often, stretch marks become visible if a person achieves drastic gains in a very short time. It’s because massive muscle growth makes it hard for the skin to stretch at the same rate that the muscles grow at, causing stretch marks. Look for them on the upper lats, pectorals, and biceps.
6. A Shockingly Fast Transformation
If you see a person who has been in the same shape for a long time and then without any particular reason has become a lot more athletic, it may be the result of steroids. Of course, if a person starts to lift for the first time and does everything properly, great results are easy to achieve even without steroids.
However, if these results are so great that a person gained 10 pounds of muscle and leaned out a lot, it’s safe to say that the person is either using steroids or is a genetic monster.
