ok this is prob just a coincident but here it goes, for almost 4 years i had severe lower back pain from injuries during grappling matches/greco and sloppy clean and jerk form etc, pain was unbearable, to a point that i would sneeze anf had to catch myself from falling down to the floor, 20 min to put sucks on and constant pain and agony during the day but i kept going, went to see a doctor he said i would never compete in grappling/wrestling or be able to lift more than 40 pounds off the floor, i went to the gym that day and never stopped squatting or doing deadlifts, i think when u do stop it gets worse, anyways i did a 6 week cycle of test P at 250mg a week, and i swear the pain just was gone and to this day, 3 years later no pain at all and better than ever
