Riiiight, cause research chem companies "NEVER" mislabel or misdose their products....
Typically I don't mind a lil' extra dosing with a serm, but try getting over dosed clen with a 36hr half life, or over dosed t3 that will quickly turn your anabolic cycle into a muscle eating fest and potentially jack your thyroid permanently....
You've got to make sure that you get your chems from a reputable source just the same as your supps, and even then, don't be surprised when they one day get the spotlight for messing something up, purposely or not...
