Established folks forget how little newbys know sometimes. So out of respect let me give you a brief primer as to why you limit cycle.
The drugs you are taking mess with important parts of your bodies self defense system (Endocrine) and your testicles ability/willingness to produce testosterone naturally.
While what you are taking is safe and largely natural (safe to a point) if you go too long on the 'juice' you greatly increase the risk that your body will NOT be able to reset. Now you think to yourself, 'that's okay, I will just do this for life'. While that may be an option - when your young it's a dumb option! As will all exteral substances your body will adjust and you have to keep increasing the dosage....imagine how high that could be when you 70 or 80 let alone older...hell just go to age 40 for that.
Safe or not that would not be a good option. The proven rule is three months on and three months off. Give yourself a chance. Otherwise you WILL break yourself and not in a way that can always be fixed. Ask some of the guys who learned to use while in prison with no advice or supervision....ask how their bodies and kidneys are doing 30 years later. You may end up stopping now.
This is not said to run anyone down or to cause fear. This is just the basics of why you run cycles and have PCT between cycles.
There is more so please keep researching and learning.
Good luck to you and everyone else just like you! Thanks for being here.
