Mike, nitrotain is Ethyloestrenol, rumor has it has a 19:1 anabolic to androgenic index where as test is 1:1 and deca is 4:1. Its prescription only and comes in a paste.
Friend has used it. Zyglamail hit the nail on the head, although it is not a roumer, it's a documented fact, it is also a very safe drug commonly used by female bbuilders. It's fairly easy to come across over here but a tube won't last you too long, may not be worth the $. A 60g tube will only last a few weeks.
And don't leave the shit on your tounge too long !
