I just finished ny first week of Sarmsearch's S4. Good to go. Can feel the effects after a few days and I'm starting to see a nice recomp change already. Maintained exactly the same weight last week but dropped another half inch off the waist.
@clman, personally I'm using my sarm solo... I'm sure they would make a great addition to an AAS cycle. I'm going solo on this run to get a good feel of it, how well it works/how i react etc,. I'm also coupling it with clomid 50mg ed, hopefully which will counter any suppression from it. But we will see in a few weeks when I get my bloods done.
