trens effects diminish after 8 weeks...if your crusing are you on for good? if so run it 10 weeks then off 4 and repeat..i did that for a few years and was as jacked as i could ever be...tren isnt as toxic as people say ive had blood tests while on and showed no issues or elavations for liver kidneys etc...stay hydrated and your good to go..if you plan to cycle off and do pct stick to 8 weeks
