you could. But IMO i would never get a pre-made stack. i think it is best to be able to control the dosage of each product yourself. u might find you need a higher dosage of one over the other, but with a premade stack u have to increase both which could lead to side effects you do not want. just buy the two seperatly and control the dosages yourself. i think you will see better results. also ive read that it is better to use one compound for a bit and then add another or run a bridge. what u could do is run a bridge cycle like say u wanna do a 6 week cycle. you could do your first compound weeks 1-4 and then run the second compound weeks 3-6. or you could run them both say one compound the first week and then start the second compound week 2. there are lots of options to consider.
