Why a suggested 4-6 week limit?

[Jeff Rippe]

Just curious why the suggested 4-6 week limit on a cycle? This seems to be a generic recommendation among all manufacturers. What happens after 4-6 weeks?

Many professional bodybuilders run their "stuff" continuously for years! I know THAT is bad for health but why 4-6 weeks on a PH?

Well 4-6 weeks is a industry standard for the simple fact of health in my opinion. If any sides rear there ugly lil heads you wont be to far into cycle to discontinue use and recover.
