many things that are methylated aren't necessarily hepatoxic or cause liver problems. That being said, Retain is one of those products that DO NOT cause problems. I have taken it myself, and megadosed it and taken it on an empty stomach and have had no problems........
ALSO, i have NEVER experienced heart palpitations on the product dosing it in the way Force of Green mentions. So saying the product is crap is not a worthy statement. It may have been crap for him but is not a crappy product by any means! and i DO agree that Retain 2 IS BETTER! :thumbsup:
