It was from Focused Nutrition, which appears to be well regarded. Also I had the strength bump that almost everyone gets between week 2 and 3. Not saying it couldn't have been some "funny Osty" though.

vujade meant that it was some compound other than Osta, not that it was no good.
I have some OL Osta that I'm going to try out at some point, and I should see if the effects are similar or different.
