same applies like other oils of when to start and stop, but you have to watch for estrogen sides on this product. I couldn't handle 1/2ml day without estrogen needing to be taken care of.

Your current cycle already has PRO-MT-200 which will be 700mg tren and 700mg MAST. Then if you add shredded, your tren will be even higher too. you don't need more tren then this.

I would take 1/2 ml shredded per day and reduce PRO-MT-200 by 1/2 ml as well.

good job too. clearly a guy who knows what to do and especially at your age far superior than guys 40 years younger.
