Brutal is not the word. That shit sucks ass bad. I used 1cc of it before, and after that one shot, I threw that bottle plus another unopened bottle in the trash. Injecting battery acid would probably feel better than T-400. Thats probably why it is not often faked. People think 400mg/cc is awesome. Then they realize after the first injection what a mistake they made. Just stick with sust. !00 times better than T-400 IMO. I know many other people feel the same way. Especially if they have tried it before. I could not imagine doing more than 1cc at a time. It would be crippeling. Test prop at 200mg/cc is a baby shot compared to T-400.
