Does growth hormone spike after the 5 days of ProLon?

Some studies have demonstrated a significant increase in growth hormone during a prolonged water fast (typically in days 3 to 5), but the clinical studies on ProLon did not report growth hormone levels, so we can’t definitively say if the same impact occurs with ProLon.

ProLon suppresses IGF-1 (insulin like growth factor 1), but the impact appears to be transient, and IGF-1 levels slowly return to their starting levels following ProLon use.
