At your age and bodywt for ht, you are nowhere near your upper limit. The cycle you propose as mentioned is as stated, irresponsible, reckless and just plain stupid. At 20 years old with such a cycle you'll make it extremely difficult on yourself for any future runs. Further, it is this kind of recklessness that makes it bad for the rest of us who try to do these things as responsibly as can be done. Do yourself and everyone else a favor and put in the work for at least a few more years, ya won't regret it.
