we write a bunch of different numbers on slips of paper put them in a hat and see what comes out!! if you're lucky you'll get a good dose!!
I think for the most part it's just passed along info especially getting into combos and higher doses as there isn't much reading material (ie studies) on this. most of it is passed along form experienced vets which is a big reason why there are sooo many varying strategies out an about!! if there were lots of good studies on how much trenbolone should be run with 750 mg of test, versus 1000 mg of test 400mg Deca-Durabolin - nandrolone decanoate - with some Winstrol - stanozolol thrown in at end and and studies on what kind of p-c-t's were most effective for these kind of cycles, well then we wouldn't be arguing all the time!! we'd just point to the studies and case closed!! the studies would be posted as stickies and we wouldn't spend our days on a board plotting our next strategy from a thousand different inputs!!
