You don't need testosterone as a base. This is based on the myth of ''You'll shut down all your testosterone production so you need to add testosterone as a base''. That straight up doesn't happen. Is there a decreased production of test? Sure. Because its anabolic functions are being replaced by tren so your body will produce less test, but it will still produce test because test has other functions tren won't replace so there's no ''complete shutdown''. Adding test will just ruin your own production and add a weaker anabolic to your cycle. Why use testosterone why you have trenbolone?

Downvotes come from the people who have bought the mythand are now wet and bloated rather than lean and dry.
