Hey guys I usually take animal stak. but i was thinking about trying out m-stak. I am not a competitive lifter so testing would not be an issue. i am also going to be switching my routine to .. "Bench Like Animal" By: Vag.... 8-week routine. I love this routine. last time i did it when i was wayyyy younger and i took stak and was gaining like 5-10 pounds week on max. so if you guys can let me know what you prefer and y. thnx!
