Looks like Ostrine's big brother is in town.
A new SARM labled as "LGD-4033" is on the market, and it is supposed to be 12 times as powerful as Ostrine with only 1/3rd of the dose. It also kicks in faster to boot.

Seems interesting, but pricey.
EDIT:
Seems another topic was started on it back in February. I'm a genius.
