I do better on higher tren doses, while on lower doses of test. Currently, like the OP, I'm taking Tren A, Test P, but I'm also taking EQ and anavar. Lean, hard, and veiny results. I'm running TA at 600 per wk, EQ is at 600, Test P at 250-300 pw, and var is at 300 pw (50 mg per day).
I'm not having any issues with insomnia or anxiety, and I've been running this protocol for about 16 wks. I'm getting ready to drop a few and add some different compounds for fall/winter.
Peace
