receptor overload.....??
If a person has just dome a cycle and didnt take the time off to recover and jump right into another cycle .Receptor burn out is common.
time on - time off no comming of for a month of so then jumping back on.
talked to a guy that has had the same exact problem combined with toxicty issues
he came off all steroids except 200mg of test for 4 months drank lots of water flushed his body out and now feels great jumped back on a heavey cycle no problem.
Tren can be very toxic and stressful when the body is full of a toxin it gets sluggish ,tired and almost sick feeling...The liver filters out alot of stuff in the body dirty liver means the body almost starts to shut down .
Any one that has had toxicity issues will know more about this maybe some one can chime in....
not say that its what it is but just a thought.
