Tweetit looks good, I am currently on a cycle a lot like that. 200mg/2Xwk of eq/bold, and 250mg test e 2x/wk.
SO 400mg/eq and 500mg/test a week. it gives great results.
The eq i love it, it makes everything hard, but it seemed like it took a while to kick in this cycle, but I usually use D-bol at the start but instead I am in the middle.
As for water weight I went from 9.8% bfi to my current 10.4% bfi, so not much water weight. But some, my weight went up a solid 12 lbs, and I still have 6 full weeks left.!. and only a week in a half into my 6 weeks of d-bol. 25mg ed.
You still are young, but it is a beginers cycle. But I think you'll like the results and for what your doing it for(athleticly speaking) I think it will keep you vary mobile and flexable! I haven't noticed a decline it any of that!
