osta ldg are nice ones, but you should use it with a test base. SARMS DO CAUSE SHUTDOWN, so use a test base with it or at the very least do a pct after it. but dont think "your off" while using sarms.
I liked osta, kinda reminded me of tbol, but i used it with test.
i would rec it for about 8 weeks with a pct and HIGHLY rec a test base with it.
