Try posting a cycle w/all ancillaries and pct AI HCG DA(if running a 19nor) etc!
Serious mass?! Look into just test/Nandrolone(ever try NPP)?? What about test! It's all dictated by your diet/training program!
Also where is your AI/HCG/etc pct? No one is going to lay out a cycle for you(research the compounds your thinking of and post a full cycle layout)!!
