The HPTA is a biofeedback loop that regulates hormone production in the body by reading what the body considers as homeostatic levels. When exogenous testosterone is introduced the feedback loop reads the overload and signals the pitiuitary to cease production of certain hormones such as LH in an attempt to regain homeostasis.
Technically, testosterone shutdown by the HPTA is caused by excess testosterone. The HPTA can be compared to a thermostat. Excess heat causes the air conditioner to come on. When it returns to an acceptable temperature, the AC turns off.
As stated above, TRT is not a cycle... It's a life long commitment. You may wan to advise your buddy to seek further treatment from a Dr. Who is a little more knowledgable in TRT. If you were a good friend you would get on him to do ALOT of research on his own behalf. It's his life, his health and A 4 week "cycle" will do nothing for his test in the long run. 4 weeks would probably not even shut Down his system but he would prob. Have much lower overall testosterone after the initial 4 weeks. It sounds a little sketchy, double check his protocol and give us more info about the 4 week run. Maybe he is due back for BW after 4 wks and adjustments will be made accordingly.
