If you lift weights, you surely do heared about it. Steroids increase your power and you will gain more muscles. Why not bring it to San Andreas?
After some time I decided to script a modification which will make you able to use steroids. Its not a small time script which will increase your muscle after buying steroids, but you have to train (benchpress or dumbbells) to see the effect! You can visit a really serious guy behind the gantom gym who will sell steroids to you.
