Hang in there brother. Train your good leg as long as it doesnt cause pain on the bad leg. Keep training your upper body too, and if you can afford it get some soft tissue work, light therpy, maybe even accupuncture on that groin...Im all about trying to find ways to improve recovery these days and wish I did more of it back in the day instead of grinding it out through the pain and coming back way before I should have each time...again, I loved football more than life itself...and wouldnt change a thing other than train smarter....
get those books I mentioned, you can go wrong with Bill Starr it is old school but still applicable, as is the Nebraska book. Supplementation can do a lot of neat things for you, the ones I mentioned are not sexy but they will do you some good over the long haul if taken consistent. if you want to get sexy, maybe ask Need2 on here which supplements he has that might help that do not pose any risk to testing positive, I think he has a bunch of suppelements that boost T and anabolic activity that are natural if you want to give it a shot and have the cash. Id keep a foundation though of a multi vitamin, 2-5g vitamin C a day, BCAAs as many as you can afford, EFAs taken multiple times a day, anti oxidant formula, and once your back to weightroom full speed creatine and beta alanine.
Be careful with the sauce....it was many many years ago but I know more then one guy back in the day who thought he was taking EQ or something that would clear his system, and it turned out to have some nandrolone in it and he was popped by NCAA....if your doing UG stuff you never know what might be in it, and you cant risk testing positive a year later from something you didnt realize you took...if your gonna play that game Id only go pharm grade T with PCT, or as much as folks hate orals Id feel more comfortable taking T plus an oral for a stint and getting off long before I knew I could be tested...however I dont know these days if rules changed and they can test you any time they want once you go to an NCAA program, which would make it smart to cut out the AAS for sure....but yea unless you got medical issues you shouldnt need it, do a good PCT and jump on some good supplements, heal up that groin, and tear it up brother...hit the books too, as much as I love football, it always ends for all of us at some point, and a good degree under your belt is a nice thing to have.
