So RCS used to be S4S they did a refresh and an update for product design, first time I get to use capsule sarms, I've only used liquid in the past.
I can tell you my metabolism with GW and SR has already kicked in because I never used to wake up hungry and now when I wake up my stomach feels empty like I haven't eaten in days lol, it's definitely boosted that already.
My cardio has greatly increased as well, I can go harder for longer uphill and I can go at a much faster pace and don't even feel winded or tired.
I stick with Rcs because my results have always been great, as long as the diet is on point u will see the results. I've run alot of different sarms, I will say s4 and rad are some of my favorites.
