hhmmm, never heard of this. if this is something you're feeling i think it could be from the effect of test on tendons. high testosterone damages, which in turn leads to muscle and tendon tears.
something you can do to combat this is run high cortisol production cycles like 200-300mg/test (for libido, muscle maintenance...) and eq/deca at like 600+mg/week. i recently have done this myself and plan on doing it between mass cycles from now on.
