Personally i know people who swear by the crap but i dont take it. I just reduce volume for a week or two or give it a few days off if in hurting. Reason being I HATE SEAFOOD and when i tried taking fish oil i would burp and taste fish. Its was so nasty i couldnt take it. My dad swears by some stuff called flexamin i think. I have a bottle of it in my room im going to take it when i start cutting because my workouts are more grueling while cutting for sure and i run 25+miles a week.
