i just did a 8 week cycle of deca 400mg/wk followed by winny 50mg/ed on weeks 7-10.
i have a few more shots of the winny to go.
i was up 20lbs, now i'm trying to cut while the anabolics are still in my system. i've lost like 8 lbs in the last 3 days(simply because i've stopped stuffing my face with anything in sight)
i'm definitely getting pumps at the gym, but i just cant tell if the winny is making any difference.
anyways, about your question . . . i guess it depends if deca shuts you down and how you react to test. i have never been shut down on deca and do not tolerate test well . . . so for me i would not use test.
