You shouldn't even consider using a prohormone/steroid like Havoc until you have done your research. This product will affect your hormonal balance and should only be used by those who have experience with prohormones. You dont need these types of products to make gains. If you are seriously considering turning to the "dark side," go with something a little less milder, like a test booster for example. There have been alot of issues with Havoc and or Epistane dealing with gyno rebound because people are unsure of how to run a proper PCT due to this products ability to already reduce estrogen throughout the cycle. Please think twice about this.
