Deca is awesome for joint pain. I mean it disapears. I got good gains but in spite of my precautions I got delayed Deca Dick. It's temporary. The wife and I are married 22 years so it's not like sex is a HUGE issue. And old Willie finally came back. But if you are a young, daily, Sex head, I really would stay away. Just my opinion. Great steroid. one of the best. BUT deca dick is REAL, my brothers. Load up on test.
