Ph Cycle (Prohormone Cycle)
Most commonly a 2 to 8 week regamin depending on substance and dosage, followed by a recovery phase of equal or greater time. During this PH cycle, calories are increased and training intesities are decreased to facilitate recovery.

After most PH cycles, certain substances are used to accelerate recovery of natural testosterone production. The most common tools used are anti-estrogens. These serve the dual purpose of decreasing estrogen levels that are commonly elevated after a cycle and signalling the body to produce more testosterone.
