we were told no supplements, no protein no creatine not sure about the specific ones you`ve mentioned but i would say no. the only thing that most guys took was a decent all round vitiman, just to fight of the bugs while you run down.
you can take certain supplements when you pass RT but ask first dont want to fail a drugs test???
If you took the likes of Di Arginine Malate and Taurine, You would certainly not fail the drugs test, taurine is used in red bull *text deleted*. Creatine is nitrogenous organic acid that occurs unnaturally in vertebrates and helps to supply energy to muscle and nerve cells and occurs in the body. You may not be allowed to take any of this but you would certainly not fail a drugs test with this or any other legal supplement. You would still pass the drugs test if you took anabolic steroids etc, the drugs test only really tests for banned substances, drugs etc.
