Yes, that’s correct.
Although I would challenge you not to add a second steroid the very first cycle.
Do you think you won’t achieve significant gains from blasting testosterone much higher than yours has ever been? You just don’t need two different steroids yet; you can only grow so much muscle in a period of time or acquire actual lean mass so fast. If you need to call an elevator, you must push the button. You can stand there pushing the button 100 times like an idiot, but it’s going to come at the same speed regardless once it’s been called and will take you to the same destination just the same. You can’t take the elevator farther than it can go on one trip.
And if you only use test, you can see how that alone affects your lipids, blood count etc. You will have better information for future runs.
