1. My Sarms s4 worked amazingly as a bridge
2. They sent me a bottle of osta sarms and I didnt receive it within the 2 weeks (to Australia) so as soon as I emailed them they responded within 24 hours and sent me another bottle.
thats sweet. and since im from canada, gotta go with search. And to reply to the guys comment up there osta is not s-4. Thats andarine. and no osta isn't s-1 either. people on forums call it that but thats an old shitty sarm.
Can someone clarify the difference between the two? For our purposes atleast? I used S4 before, and loved it... still have a bottle left to use in my bridge in 2 weeks..
