hey brother... you dont need test to gain 10 lbs of muscle... its obviously a great choice to do so but you can absolutely do it with sarms but even if you were on test, your diet still dictates the ability to put on the size you want... clearly , when your in an anabolic state and using performance enhances, its speeds the process or can go lengths you would never get to on your own, but just because your using anything does not guarantee you will gain anything... its an entire package... the compounds have the capability but its like a puzzle, you have to put ALL the pieces together to solve it or you end up with half a picture or 3/4 a picture etc... its not complete and you never get the finished result... you absolutely can do it with the selected sarms but its up to you to piece together the diet and training that can accommodate it... to answer your question easily, YES you can add that size with those compounds...
