The act of pyramiding has no valid basis. Introducing the androgen into the body at a lower concentration and then increasing the dose doesn’t allow the body to become "accustomed" to the exogenous compounds in any way.
Furthermore, tapering off only prolongs the time it'll take to regain HPTA functioning. Taking the lower dosages causes LH suppression yet barely provides any anabolic effect, perhaps none at all! So, if you’re a person who likes to get LH suppression with minimal gains, go ahead and "pyramid."
