Over the last year or so, getbig has largely become the anti-PCT bodybuilding board, and for the life of me I do not understand why. I've yet to hear anyone offer up a reasonable explanation. Most will say, just don't come off and you don't need a PCT...that's true, if you do not come off you won't be implementing a PCT plan. Even so, everyone, every last person on earth comes off at some point. A lot of guys do not want to stay on year round or the vast majority of the year like a lot of you guys do...I would say the guys who stay on year round fall into a very small minority. Further, if you stay on year round or most of it year after year, at some point in time your life is going to change, there's going to be a reason for you to come off. Saying you're never going to come off is an irresponsible statement as you have no way in predicting the future.
At any rate, if you're going to be off for 12wks or more, a PCT plan just makes sense. No, there's no PCT plan on earth that's going to promote a full recovery on its own, you won't finish your PCT plan and have your test levels back to where they were prior to supplementation just because you ran a PCT plan. However, you will stimulate production, provide your body an adequate amount of testosterone to function properly and you'll do so all the while your natural levels continue to climb.
More importantly, this just protects your health. Low testosterone levels are tremendously damaging to your health as this is one of the single most important hormones your body produces. A lot of guys assume if their libido isn't severely suppressed and they don't have any erectile dysfunction problems they're in the clear, but those are just two aspects of a low level condition, two of many and not everyone falls prey to all the symptoms.
Granted, if you are going to be off for an extended period of time, your natural levels will increase on their own assuming you didn't suffer from a low level condition prior to supplementation and did not severely damage your HTPA during supplementation with poor practices, this is true, they will increase on their own. But it's going to be much slower, and there will be an extended period of time where your levels are extremely low and there's simply no logical reason for putting your body under this kind of stress when a simple and extremely cheap PCT plan can prevent it.
Anyway, that's my two cents.
