sure you can bro... you can really run whatever you want, however you want.. the question is should you or would it be wise to? me personally, im not big on those kind of cycles, never have been.. its just not the wisest thing to do health wise nor in terms of sustainable gains but everyone has their own way or mind set and thats perfectly fine... im just giving my opinion on what ive seen success and health wise over all these years.. ive ran an oral only, my first cycle and i did well on it during the cycle but after, not so much... rick will remember these kind of cycles we used to run... i ran helladrol on its own and i followed it with superdrol for my next and that was literally the worst experience i ever had with any cycle in all these years... .
