Yes, ostarine is orally bioactive whether a liquid or a pill. The research chem companies are the ones selling ostarine suspended in PEG300 or sometimes DMSO. I think it was inevitable that someone was going to start selling it in pill form. If it's affordable and legit then it could really cut into the research chem market.
I don't think it's highly liver toxic... like a mild oral prohomone at the worst. I do think it can raise estradiol levels. No, I don't have blood tests to prove this, just anecdotal evidence.
EDIT: Just checked out the vendor Bill mentioned. That's a *great* price if it's legit. Supposedly they have a good rep. May have to order some myself.
