I know this is a dumb question but...... what is the danger in running back to back cycles? for example, completed 4wk celtic d drol with 4wk pct , my schedule just got changed allowing me some extra time I would like to take advantage of in the gym, questioning another 4 wk of triumphalis ( it would be about 1 month since finishing pct from 1st cycle) am I just asking for trouble or is this doable???
