Ok so it says to use for 21 days then take some time off. Is it possible to take it for a 6 week period rather than just a 3 week? Would there be any benefit to this? What should I take with M-stack to try and maximize my gains? I have used m-stack before but just thought I would ask the question because I would like to see what some possible responses/recomendations are. I am currently taking in 5000 calories a day, I use weight gainer, ZMA, multivitamin, and Nano-vapor currently. I have used m-stack before but was just curious if there was anything I could use in conjunction with the product to maximize muscle gains.
