I have friends who bought from science.bio and chemyo and they liked it, try to see for them.
Would you try it systemic or topical?
I'm also seriously thinking about starting with the andarine... Anyway if you proceed let us know and update us please
I prefer to try it systemic , S4 can work for define my abdomen too.Lately I notice a little fat in this area
Some say that the liquid version for take is better
