I just started week 4 of 600 mg/wk test and 400 mg/wk deca. I am out of deca and have only sust left. (Wasn't able to get back to Mexico soon enough). After 4 weeks of deca, will it do any harm to switch to sust??? I plan on running cycle for 10 weeks total, I've got enough test and sust to finish it that way...
any input appreciated!
