there's a multitude of reasons why that's not optimal... you CAN run sarms with aas but you are not going to get near the results you would running them separately... to me, its a waste of time and money... sarms are not cheap so when you run them, you want to get the most out of them... receptor competition is evident if you run them together which lessens the effect... even if there were no competition, i would not recommend them as a kickstart, especially s4, being it has the worst sides that could cause you to stop or run it at a less than optimal schedule going 5 on and 2 off to combat the vision sides... I have said this A MILLION TIMES, that sarms are best utilized as a bridge in between cycles to hold on to and add to gains... the way you want to do it is not optimal in any regard... run an oral aas as a kickstart to your cycle...
