i really like the cycle layout itself bro... good choice of things... very bad choice of dosing... what exactly are your goals here? my main concern is that your so undersized for 6'4"... your nearly 25 pounds underweight at least so in all honesty, i would never recommend a cycle like this yet... what will happen is you will eventually grow far to fast and this will cause an excess of amount of strain internally, especially on ligaments and tendons, simply because you could have made this growth on your own... you may THINK you make huge gains on a cycle like this but only getting to normal weight is like no gains at all, and at what cost? you are setting yourself up for long term injury problems... remember, once you stretch ligaments, they dont ever return to normal... they are always a problem... keep this in mind bro... my recommendation would to be to put on AT LEAST 15 more lbs. on your own... THEN you would cycle but if your intent on it, then i'll help you at least run it right but just know what is likely in the future
