I've been on Test Enanthate 500mg/week for 1 week so far. How long until I start really feeling the benefits of this stuff? I've read anywhere from 3-4 weeks until I see anything. But I have gained 5 lbs this week alone. That could be coincidence, but my diet hasn't really changed at all. I'm wondering if its the test that made me gain weight or if it was just coincidence.
