Please understand Tren cycles of this nature are very dangerous, they are hard on your heart and blood pressure and if you desire to remain safe they are not something you will ever want to mess with; we have simply made you aware of what some do but this does not mean you should do it to. The reality is very simple, there is hardly a man out there no matter how far advanced that needs more than 100mg of Trenbolone every other day; we can however make an exception of making this dose daily the last 10-14 days before a bodybuilding competition for a hardening affect but thats it.
Typical normal-service engine valve-train components may be too lightweight for operating at high revolutions per minute (RPM), leading to valve float.  This occurs when the action of the valve no longer completely opens or closes, such as when the valve spring force is insufficient to close the valve (it does not fully rest on its seat even though the cam would allow the valve to close) causing a loss of control of the valvetrain, as well as a drop in power output.  Valve float will damage the valvetrain over time, and could cause the valve to be damaged as it is still partially open while the piston comes to the top of its stroke.  Upgrading to high pressure valve springs could allow higher valvetrain speeds, but this would also overload the valvetrain components and cause excessive and costly wear. 
As for individual use of a personal nature, outside therapeutic treatment, this is where we will find the vast majority of anabolic steroids. It is here we will also find the biggest problems, not in terms of ill-effects of a physical or mental nature but of those surrounding legality.
