Side effects such as Gyno are typically avoided by adding an AI (aromatase inhibitor) to your cycle as both Dianabol and Testosterone convert to estrogen; hence, estrogen-related sides like gyno and water retention can get out of hand quick, fast and in a hurry. Common AIs are Arimidex (anastrozole) or Aromasin (exemestane). Adex is usually dosed at 0.5mg EOD (adjusted up or down if/when appropriate) and Aromasin would be 12.5mg ED or 25mg EOD. pprivorn, although not an actual AI, is also popular as it is a pure androgen which has a physique hardening effect. But the AI would be the most popular starting point with a Test/Dbol cycle.
