While you go to extremes, you bring up the argument I always make in this discussion - at what point do things become illegal? A guy takes a pill or injects something into him - we all agree that that is illegal. What if they get laser corrective eye surgery? Its enhancing their performance by improving their sight - is that legal? What about someone who sleeps in a hyperbaric chamber? They are training their lungs/blood to work with less oxygen and, thus, improving performance. Is that legal? What if someone trains in high elevations? That's also improving their performance. At what point do we draw that line?
Gone are the days where you could go to a doctor and get a script to buy steroids from a pharmacy, due to steroids being abused by athletes and bodybuilders they are now illegal. The only way to buy steroids now is on the black market, either from a dealer or from an online source. When steroids were legal and were purchased from a pharmacy, the only steroids you could get were pharmaceutical grade which were extremely high quality and worked far better than the “underground” stuff. Today pharmaceutical steroids are harder to get hold of and cost a lot more, for this reason many people opt for black market steroids which usually are lower quality and can cause infections due to them being produced in an non-sterile environment. Only injectable steroids need to cause concern when purchased from an underground lab, oral steroids don’t need to be produced in a sterile environment.
However, the relative gain in size will be very moderate with many anabolic steroids being far more suited for this period of steroidal supplementation. There are those who may wish to include Masteron in a bulking plan for its anti-estrogenic and fat loss effects. The latter would ensure they kept their body fat gain minimized during off-season bulking phases, but this isn’t reason enough to use it in this phase. Body fat should be controllable without it. As for the anti-estrogenic effects, off-season cycles are normally comprised of large amounts of aromatase activity due to high doses of testosterone. Progesterone activity is also commonly high with the addition of Nandrolone compounds and possible Trenbolone. Consider additional Anadrol or Dianabol and this estrogenic activity can become very pronounced. Unfortunately, while possessing anti-estrogenic effects, Masteron will not be strong enough to combat this level of estrogenic activity.
