No, stacking it with test has nothing to do with its toxicity. Every substance has its own profile. Tbol happens to be an excellent muscle builder, low toxicity, can raise blood pressure and is not a DHT.
People will take with Test because Test should always be your base.
Now if you have never taken any AAS before then I would highly recommend you familiarize yourself with what compounds do what, their side effects and dangers, and oh of course - first cycle is always Test only.
