cancer I am sorry could not say how well deca worked because I ran with anadrol. I know I how felt with it- like I said was great. I ran 600 mg of test and 400 mg of deca split twice a week-ran deca 12 weeks test 14 weeks .I will run it next cycle with just test - my last on before I run tren
I did not see any "deca" sides with that dosage I ran. Good luck man
