"However, things were not to be as simple as Jimmy first thought. “A couple of UFC fighters, who are 12 months into their two year bans for ostarine, messaged me”, he explains. “One is quite a famous fighter, and he swore on his kids life that he hadn’t taken ostarine. He’s got two kids and is well paid. He sent 20 products in to be tested and every single one came back negative for ostarine. Straight away, I think – oh shit. I am thinking that even if it was that product or a contaminated supplement, or a contaminated batch, then the odds are low of it coming back positive."
I just don't see the logic in this. Why would a supplement company include ostarine in their BCAAs and protein pancake mixes? Ostarine is a quite expensive chemical, and sellers have nothing to win by adding them in other supplements. It would just become too expensive for them, or it would be in so small amounts it would apparently become useless.
However, I still think you should be careful with Ostarine, as this Contrarian And Free post on Ostarine indicates.
