Which steps should you take after a cycle of testosterone booster?

Prohormones: If you are referring to preps available in bodybuilding shops called prohormones, i would recommend avoiding them. The do work, but like oral testosterones, are very hepatotoxic. Transdermal of injectable testosterones bipass the liver totally, and are much safer. After 3 months on therapy consider a 10 day course of injectable HCG to restart your own testosterone production.
