deca is not the name of an ester. decadurabolin or "deca" was a name trademarked by organon. now, i agree that decanoate is one type of ester but it's not the same thing as deca durabolin. don't confuse the issue further. (not a flame strengthmonster )the question has been answered quite well. nandralone is the drug- yes, the metabolites of nandralone "can" be detected up to 18 months. although I know one south florida football player who passed a random drug test and had used a large amount of norma deca within 3 months. he took the shit over the summer without knowing about detection times. i have no idea why he passed. maybe they didn't even test his sample or perhaps they didn't test for that particualr compound. either way it was only 3 months and he had no problems. anyone else care to specualte as to why...
