OP you don't know what you're talking about, it's an anabolic steroid that will make you have a performance increase whether you take it the day of the fight or cycle it for 6-8weeks during training camp. Of course you would get the most benefit by taking it during camp so that you can push harder, longer but to say you won't get a benefit taking a steroid the day before or day of before a contest is just not a truthful statement.
