In general, once steroid use stops, the testicle begins regenerating lost tissue. Studies in rats show that the process is slow and often doesn’t recover the full pre-steroid use size (although it can get very close). Leydig cell counts often remain lower than original, suggesting that testosterone levels may be reduced in the long run. In practice, the longer period you used the steroid for (or the higher dose you used), the longer time you will need for your testicles to recover. Most men are able to recover most of the lost size but may notice that they don’t get quite back to the original size, a lower baseline testosterone level or permanently reduced sperm count. This is especially true for long term or high dose users.
The number of players who have admitted using steroids in a confidential survey conducted by the NCAA since the 1980s has dropped from percent in 1989 to percent in 2003.  During the 2003 season, there were over 7,000 drug tests, with just 77 turning up as positive test results.  Scukanec claims that methods were used to get around the drug testing, whether it be avoiding the tests by using the drugs during the off-season, or flushing the drugs out of your system. This was used with a liquid he referred to as the "pink."  He stated:
If you're going to use any injectable gear, then of course you're going to need some "darts." You can pick up syringes at your local pharmacy unless your state has certain restrictions. Also, you can purchase needles online. Just do a little searching around and you'll find several places that'll hook you up. Syringes will run you around 50 cents apiece. Note that it'll be more difficult to obtain needles (at least from the larger, more "legit" companies) if you live in California and Illinois. You'll usually need a doctor's prescription in those states. Still, if you look around enough, you can get what you need.
