How short is short? If you want a short cycle, your best bet is a shorter ester. Test prop or preferably even test suspension/TNE. Cyp/Enan take a while to kick in and by then your cycle will be over, but shorter esters must be pinned more frequently and are generally more painful.
Why do you want to do a short cycle though? Best bet is to go back a page and read the "sticky: first cycle and pct". That will cover everything you need to know. 8 weeks of prop is probably the shortest you'd wanna go
