When to start Tribex

I’m in the final few weeks of a cutting phase, and ordered my first cycle of Tribex in anticipation of getting back to bulking once I reach my goal. The Tribex will be here before I’m ready to bulk, though. Should I hold onto it until I start, or could it help me in my final days of cutting? I know that increased Testosterone levels can facilitate fat loss, but I’m just curious if anyone else has any experience in using Tribex as part of a cutting phase. Also, would using it now reduce its effects later on when I am actually bulking?
