Theres differnt types of steriods. Not all will give you the same physical results, so there is no way one can say they're 100% sure he isn't unless he does blood work.
Ha, sorry 2-0...didn't mean to turn your thread into a steroid discussion.
Sure, there are a ton of steroids out there. Narrow it down into banned substances and you have a pretty fine guideline as to what is and what isn't allowed.
Strength
You know its about 12-16 weeks to run a proper cycle? Then you have a month of PCT (Post Cycle Therapy). That's 5 months. Then you have to give time to get it out of your system (depending on the AAS you took).
Endurance
Only works while you are on a cycle. You cannot build endurance on gear and retain it as if it were muscle. Any endurance chem is simple, it allows your red blood cells to retain and absorb more O2.
So for Manny to be on, he would have to take a good 7-8 months off from fighting if he wanted to build solid strength on a proper cycle without being caught, given he doesn't put on 20+ pounds. Strength = Muscle
Don't want to get into technique, movement, hips, etc. because when it comes down to AAS strength = muscle
Endurance, you have to be ON the gear for it to enhance your endurance. He's been tested plenty of times.
So someone, anyone, please tell me at what point....exactly...did Manny Pacquiao take steroids? I would love to hear it.
