for a first cycle..deca and Sus are always a great combo.
Your dosages are low, but hell, if it's your first time, go for it.
You might want to find some Arimidex just in case. 300mg of Nandrolone can affect your nipples especially if you are sensitive.
Not so sure about E/C/A though. It's an OK alternative to cut fat but you should expect some water weight from the DECA/SUS anyhow.
